Here’s What to Do if Your Hydrangea Is Not Blooming

A hydrangea in full bloom is one of the most rewarding sights in a garden, but what happens when your plant produces lush foliage and no flowers? It can be frustrating to nurture your hydrangea all season only to end up bloomless.

The good news is that a hydrangea not blooming is often a fixable problem. From pruning mistakes to environmental stressors, understanding the common causes and how to address them will help your hydrangea flourish with vibrant blooms once again.

Common Reasons Why Your Hydrangea Isn’t Blooming

Hydrangeas are hardy, beautiful plants, but even the most seasoned gardeners encounter challenges when it comes to getting them to bloom. If your hydrangea isn’t producing flowers, several factors could be at play. Identifying the cause is the first step toward bringing those gorgeous blooms back.

Below are the most common reasons why hydrangeas fail to flower and what you can do to solve each issue.

Improper Pruning (Removing Buds Accidentally)

Pruning mistakes are a leading reason for a hydrangea not blooming. Hydrangeas differ in how they produce blooms, so understanding your plant’s specific needs is essential.

Bigleaf (Hydrangea macrophylla) and oakleaf (Hydrangea quercifolia) hydrangeas bloom on “old wood,” or stems from the previous year. Pruning these varieties in late fall, winter, or early spring removes the buds for the upcoming season, leading to healthy foliage but no flowers.

Panicle (Hydrangea paniculata) and smooth (Hydrangea arborescens) hydrangeas bloom on “new wood,” or current-season growth, making them less affected by pruning timing. However, over-pruning can still limit their ability to produce blooms by diverting energy from flowering.

Gardeners sometimes remove healthy buds unintentionally while deadheading or pruning, particularly if buds are small or not yet visible. Cutting too far down the stem can also eliminate future flowering sites.

Solution:

• Know your hydrangea variety. Old-wood bloomers, like bigleaf and oakleaf hydrangeas, should only be pruned right after flowering, usually in late summer. New-wood bloomers, like panicle and smooth hydrangeas, can be pruned in late winter or early spring before new growth begins.
• Prune lightly. Focus on removing only dead, damaged, or crossing stems to encourage healthy growth and prevent disrupting future blooms.
• Be cautious while deadheading. For old-wood varieties, avoid cutting too far down the stem. Look for swelling buds and trim just above them.

Don’t worry if you’ve over-pruned. Most hydrangeas will recover with proper care and should bloom again the following season.

Late spring frosts are especially tricky. The plant may appear healthy, and leaves may still emerge, but damaged buds often fail to produce flowers. Younger plants or those planted in exposed areas are more likely to suffer from cold damage.

Solution:

• Protect your hydrangeas during late frosts. Keep an eye on the weather forecast in early spring. If frost is predicted, cover your hydrangeas with a frost blanket, burlap, or an old sheet to shield the buds. 
  • For long-term winter protection, wrap your hydrangea in October using chicken wire or burlap, then fill the enclosure with fallen leaves from your yard. This added insulation helps keep delicate buds warm and protected throughout the coldest months, improving your chances of beautiful blooms in spring.
• Mulch to insulate the roots. Apply 2–3 inches of organic mulch, like bark or straw, around the base of the plant to regulate soil temperature and reduce stress during winter and spring.
• Choose a sheltered location. Plant hydrangeas in areas protected from cold winds, such as near a fence, wall, or taller shrubs. South-facing spots that receive some morning sun are ideal for reducing frost risk.
• For regions prone to unpredictable frosts, consider growing varieties that bloom on new wood, such as smooth or panicle hydrangeas, since their buds form later and are less likely to be affected by spring cold snaps.
• If cold damage has already occurred, focus on plant recovery. Fertilize lightly with a balanced fertilizer to encourage healthy growth, and avoid pruning damaged stems until new growth begins.

Insufficient Sunlight (Especially in Shade-Tolerant but Not Shade-Loving Varieties)

While many hydrangeas are known for their ability to grow in partial shade, there’s a fine balance between enough light for blooms and too much shade for flowering to occur. Hydrangeas, especially bigleaf and mountain varieties, need several hours of morning sun to fuel their energy for flower production. If your hydrangea is placed in deep shade or an area with filtered sunlight throughout the day, it may grow healthy foliage but struggle to produce blooms.

Too little sunlight doesn’t just reduce flower production—it can also lead to weaker stems and slower overall growth. In particular, bigleaf hydrangeas are susceptible to this issue when planted in overly shady locations, while panicle and smooth hydrangeas tolerate brighter conditions better.

Solution:

• Observe the sunlight patterns in your garden. Check whether your hydrangea is receiving at least 4–6 hours of direct morning sunlight. Early sun followed by afternoon shade is ideal, especially for varieties prone to wilting in intense heat.
• Relocate if necessary. If your hydrangea is in too much shade, consider transplanting it to a sunnier spot during the early spring or fall when the plant is less stressed. Be sure to dig a wide hole and preserve as much of the root system as possible during the move.
• For areas with intense sunlight, choose a variety like panicle hydrangeas, which tolerate full sun better than others.

Prune nearby plants or trees. If large shrubs or trees are casting too much shade, selective pruning can allow more light to reach your hydrangea without needing to move it.

Solution:

• Switch to a balanced or bloom-boosting fertilizer. Use a fertilizer with a lower nitrogen content and higher levels of phosphorus and potassium, such as one labeled 10-20-10 or similar. These nutrients encourage flower production and overall plant health.
• Avoid lawn fertilizer runoff. If your hydrangea is near a lawn, consider creating a mulch or plant barrier to prevent nitrogen-rich fertilizer from seeping into the hydrangea’s soil.
• Test your soil. A soil test can help determine if there’s an imbalance of nutrients. If nitrogen levels are high, avoid additional fertilizing for a season to allow the soil to balance naturally.
• Fertilize sparingly. Hydrangeas typically don’t need frequent fertilizing. Apply a bloom-focused fertilizer once in early spring and again in mid-summer if needed, avoiding overuse.

Inadequate Watering (Drought Stress Affects Blooming)

Hydrangeas are water-loving plants that require consistently moist soil to thrive. When they experience prolonged periods of drought stress, their energy shifts to survival rather than bloom production. Without adequate water, buds may fail to develop, or existing buds may wither before they can bloom.

Certain hydrangea varieties, like bigleaf and smooth hydrangeas, are particularly sensitive to dry conditions. Panicle and oakleaf hydrangeas are more drought-tolerant but still benefit from regular watering, especially during hot Chicagoland summers.

Solution:

• Establish a consistent watering schedule. Ensure your hydrangeas receive about 1–2 inches of water per week, including rainfall. During dry spells or heat waves, increase watering frequency to keep the soil evenly moist.
• Water deeply and at the base. Hydrangeas thrive when their roots receive a slow, deep soak. Use a soaker hose or water directly at the soil line rather than sprinkling from above, which can cause fungal issues.
• Mulch to retain moisture. Apply a 2–3 inch layer of organic mulch around the base of your hydrangea. This helps regulate soil moisture and temperature while reducing evaporation.
• Assess your soil’s drainage. While hydrangeas need consistent moisture, soggy or waterlogged soil can cause root rot. Amend heavy clay soils with compost or organic matter to improve drainage if needed.
• Monitor during establishment. Young hydrangeas or recently transplanted plants are especially vulnerable to drought stress. Pay extra attention to their watering needs during the first two years.

Immature or Young Plants (May Take a Few Years to Establish)

If your hydrangea isn’t blooming and it’s only been in your garden for a short time, age may be the reason. Young hydrangeas, particularly those planted within the last one to three years, often prioritize root development and foliage growth over flowering. During this establishment phase, the plant is busy adapting to its environment, which can delay blooms.

This is especially common with bigleaf hydrangeas, as they can take several seasons to produce consistent flowers. While it can be disappointing to wait, this is a natural part of the plant’s growth cycle.

Solution:

• Be patient. Allow your hydrangea time to establish strong roots. Most hydrangeas will begin blooming reliably after two to three years with proper care.
• Provide optimal care during the establishment phase. Regular watering, mulching, and light fertilizing (with a balanced or bloom-boosting formula) will encourage healthy growth and improve future flowering.
• Protect young plants from stress. Immature hydrangeas are more susceptible to environmental challenges like frost, drought, or pests. Use frost blankets, maintain consistent watering, and monitor for issues to keep them thriving.
• If your plant is taking longer than expected to bloom, evaluate the planting location and soil conditions. Ensuring adequate sunlight, good drainage, and proper soil pH can all help your hydrangea transition to flowering more quickly.

Solution:

• Test your soil’s pH. Use a simple home test kit or consult with a local garden center or extension service. For hydrangeas, aim for a pH between 5.5 and 6.5, where nutrient availability is optimal.
• Adjust your soil as needed.
  • For alkaline soil: Add amendments like garden sulfur or aluminum sulfate to lower the pH gradually.
  • For overly acidic soil: Apply lime to raise the pH. Follow product guidelines to avoid sudden changes that can stress the plant.
    • Please note that this is very rarely the case in Chicago area soil.
• Promote balanced fertilization. A phosphorus-rich fertilizer can help support flowering, especially if nutrient absorption has been impacted by pH issues. Look for a fertilizer labeled for blooming plants or hydrangeas specifically.
• Monitor regularly. Soil pH can shift over time due to rainfall, organic matter breakdown, or other factors. Test annually and make adjustments as necessary to maintain a balanced environment.

Pest or Disease Issues Impacting Bud Formation

Pests and diseases can interfere with your hydrangea’s ability to bloom. Insects like aphids, spider mites, and scale sap energy from the plant, while slugs or snails may directly damage buds. Diseases such as powdery mildew or botrytis blight can weaken the plant, leaving it too stressed to produce flowers.

Solution:

• Inspect regularly. Check buds, leaves, and stems for signs of pests like webbing, small holes, or clusters of insects. For diseases, look for discoloration, mold, or leaf spots.
• Remove pests by hand or spray with water. For larger infestations, use insecticidal soap or neem oil, following the product’s instructions.
• Treat diseases promptly. Remove affected leaves or stems and apply a fungicide if necessary. Improve airflow by thinning crowded stems.
• Keep the plant healthy. Regular watering, appropriate fertilizing, and clearing debris at the plant’s base will reduce stress and help prevent pests and diseases.

Hydrangeas are the showstoppers of any garden, with their lush blooms and vibrant colors. However, when it comes to pruning, not all hydrangeas follow the same playbook. Some varieties need a light touch, while others thrive with a more assertive trim. The key lies in understanding how each type grows and blooms. Pruning at the right time not only keeps your plants looking tidy but also encourages a healthy cycle of growth and flowering. With so many types—like bigleaf, panicle, smooth, and oakleaf—it’s important to know what works best for each.

When to Prune New Wood Hydrangeas

New wood hydrangeas, such as smooth hydrangeas (Hydrangea arborescens) and panicle hydrangeas (Hydrangea paniculata), produce flowers on growth from the current season. This makes them forgiving to prune, as their flower buds form on fresh stems. Correct timing supports healthy growth, vibrant blooms, and a well-maintained shape.

The best time to prune new wood hydrangeas is late winter or early spring, just before new growth begins. Pruning during dormancy allows you to remove dead, damaged, or weak stems from the previous season, giving the plant a clean slate for the year. Since these hydrangeas are not actively growing at this time, pruning won’t interfere with their natural cycle.

For smooth hydrangeas, like the popular ‘Incrediball’ or the ‘Invincibelle Limetta,’ cutting the stems back by several inches encourages strong new growth and abundant flowers. Some gardeners even cut them to the ground for a more compact plant with slightly smaller blooms. Panicle hydrangeas (including Limelight Hydrangeas and Vanilla Strawberry Shrubs) are best pruned less drastically—remove about one-third of the oldest stems and shape the plant to highlight its natural form and striking cone-shaped blooms.

Avoid pruning in summer or fall, as this can hinder the plant’s ability to store energy for the following year. Properly timed pruning leads to healthier plants with an abundance of stunning flowers that will brighten your garden for months.

Next, thin out overcrowded or weak stems near the base. This improves air circulation and prevents disease. Smooth hydrangeas, like ‘Annabelle,’ can be pruned aggressively—cut back stems to about 12–18 inches or lower for a compact, manageable shape. This approach encourages vigorous growth and large, showy flowers in summer.

For panicle hydrangeas, like the ‘Puffer Fish’ variety, take a lighter approach. Remove up to one-third of the oldest stems, focusing on maintaining the plant’s natural shape and upright structure. This variety benefits from selective pruning to support their signature cone-shaped blooms. Overpruning can detract from their elegant appearance, so it’s best to prioritize balance and structure.

Finally, clear any plant debris from around the base to discourage pests and diseases. These simple steps ensure your hydrangeas remain healthy and beautiful.

When to Prune Old Wood Hydrangeas

Old wood hydrangeas, such as bigleaf (Hydrangea macrophylla), mountain (Hydrangea serrata), and oakleaf hydrangeas (Hydrangea quercifolia), bloom on stems grown during the previous season. Their flower buds develop on old wood, so incorrect timing can lead to a bloomless year. Knowing when to prune helps maintain their health and keep their flowers flourishing.

The best time to prune these hydrangeas is right after they finish blooming, typically in late-summer. This timing allows for shaping and removal of spent flowers without damaging buds forming for the next season, which begin to develop in late summer. Pruning too late, especially in fall or early spring, risks cutting off these buds and reducing flowering.

Start pruning by trimming spent flower heads, making clean cuts just above a healthy pair of leaves. This step tidies the plant and directs its energy toward strengthening existing stems. Next, look for dead, damaged, or weak wood and cut it back to the base or a strong node to improve air circulation and support new growth. If the shrub is dense or overgrown, thin out the oldest stems at the base to rejuvenate it.

Avoid heavy pruning during the dormant months, as old wood hydrangeas rely on their existing structure for the next season’s blooms. With properly timed care, these shrubs will reward you with lush foliage and vibrant flowers year after year.

Inspect the plant for any dead, damaged, or weak stems, and remove these entirely. This not only improves the plant’s appearance but also promotes better airflow, which reduces the risk of disease. For shrubs that have grown crowded or unruly, thin them by removing up to one-third of the oldest stems at ground level. This gradual rejuvenation encourages fresh growth without shocking the plant.

Refrain from pruning during late summer, fall, or early spring, as the buds for next year’s flowers are already developing. Over-pruning during these periods can significantly reduce flowering potential.

Best Tools for Pruning Hydrangeas

Using the right tools for pruning hydrangeas makes the job easier, safer, and more effective. Proper tools ensure clean cuts, which promote faster healing and reduce the risk of disease. Here’s a breakdown of the best tools to have on hand:

1. Hand Pruners
   For light pruning tasks, such as trimming spent flower heads or cutting thin stems, bypass hand pruners are a must. Their sharp, scissor-like blades make clean cuts without crushing the plant tissue, which is ideal for maintaining healthy growth.
2. Loppers
   When dealing with thicker branches, loppers provide the extra power you need. These long-handled tools can easily cut stems up to 1-2 inches in diameter, making them perfect for older, woody hydrangea stems. Look for loppers with ergonomic handles for comfort during extended use.
3. Pruning Saw
   A pruning saw is the tool of choice for cutting through very thick or tough stems that hand pruners and loppers can’t handle. These saws are compact, sharp, and designed for clean cuts on larger branches.
4. Gloves
   Sturdy gardening gloves protect your hands from cuts, scrapes, and potential irritation from hydrangea sap. Choose gloves with a snug fit to maintain dexterity while working.
5. Cleaning Supplies
   Disinfecting tools between cuts prevents the spread of disease. Keep a cloth and rubbing alcohol or a solution of water and bleach nearby to wipe blades clean.

Investing in high-quality tools and keeping them sharp ensures your hydrangeas receive the best care, resulting in healthier plants and beautiful blooms.

1. Over-Pruning Panicle Hydrangeas

Panicle hydrangeas (like the variety ‘Strawberry Sundae’) are sturdy, reliable bloomers, but too much pruning can lead to fewer flowers and uneven growth. Unlike smooth hydrangeas, which can handle a heavy cutback, panicles, like the ‘Bobo,’ prefer a lighter touch. Removing more than one-third of the plant’s oldest stems can leave it sparse and disrupt its elegant shape.

How to Avoid: Focus on selective pruning. Remove the oldest stems to encourage fresh growth, but leave younger stems intact to support abundant blooms. Always aim to maintain the plant’s natural structure for that signature, round-shaped beauty.

2. Pruning Old Wood Hydrangeas at the Wrong Time

One of the most common mistakes is pruning old wood hydrangeas, like bigleaf (Hydrangea macrophylla) or oakleaf (Hydrangea quercifolia), in late winter or early spring. These types develop their flower buds on last year’s growth, so trimming at the wrong time can cut away all the potential blooms for the year.

How to Avoid: Wait until right after these hydrangeas finish blooming in midsummer to prune. This timing ensures you’re shaping the plant without disrupting the buds forming for next season.

3. Confusing Your Hydrangea Type

Not knowing whether you have a new wood or old wood hydrangea can make pruning feel like a guessing game. Pruning too aggressively or at the wrong time for your hydrangea type can result in bloomless seasons and stunted growth.

How to Avoid: If you’re unsure of your hydrangea variety, wait until after it flowers to prune. This gives you a chance to observe its blooming habits. You can also bring a photo or sample branch to Platt Hill Nursery, where our plant experts can help you identify your hydrangea and guide you on care.

4. Over-Thinning or Neglecting Crowded Stems

While thinning helps improve air circulation and reduce disease, overdoing it can weaken the plant’s overall structure. On the flip side, neglecting to remove overcrowded stems can leave the plant vulnerable to fungal issues and pest infestations.

How to Avoid: Strike a balance by removing only up to one-third of the oldest or weakest stems at the base. Prioritize cutting stems that are crossing or crowding the center of the plant to open it up without over-thinning.

5. Failing to Use Clean, Sharp Tools

Dull or dirty pruning tools can crush stems, leaving jagged wounds that are prone to disease. This can compromise the health of your hydrangea and delay its recovery after pruning.

How to Avoid: Always clean your tools with rubbing alcohol or a bleach solution before and after pruning. Keep blades sharp for smooth, clean cuts that heal quickly. Investing in quality hand pruners, loppers, and a pruning saw makes a big difference in the plant’s health.

6. Overlooking Winter Cleanup for New Wood Hydrangeas

Skipping winter or early spring pruning for smooth or panicle hydrangeas can leave the plant cluttered with dead stems and weak growth. This limits the plant’s ability to focus energy on strong new shoots.

How to Avoid: Take the time in late winter or early spring to remove dead or damaged stems from your new wood hydrangeas. A fresh start sets the stage for vigorous growth and vibrant blooms.

Deadheading Hydrangeas vs Pruning: Key Differences

While deadheading and pruning hydrangeas both involve trimming, they serve different purposes and are performed at different times. Understanding their distinctions will help you care for your plants effectively.

Deadheading

Deadheading is the process of removing spent flowers from the plant. This task is mostly aesthetic, keeping the shrub tidy and encouraging it to redirect energy into maintaining healthy growth rather than seed production. For hydrangeas, deadheading can extend their bloom season in some varieties, as the plant focuses on producing fresh flowers rather than sustaining faded ones.

To deadhead, simply snip off the spent flower head, making your cut just above a pair of healthy leaves. You can deadhead throughout the growing season as needed. For old wood hydrangeas, stop deadheading by midsummer to avoid accidentally cutting developing buds for next year’s blooms.

Pruning

Pruning is more structural and involves cutting back stems to shape the plant, remove dead or damaged wood, or stimulate new growth. The timing and method vary depending on the type of hydrangea. New wood hydrangeas are pruned in late winter or early spring, while old wood hydrangeas should be pruned right after flowering.

Pruning encourages a healthy framework, supports flowering, and controls the plant’s size. Unlike deadheading, pruning often involves removing more significant portions of the plant, including older stems or those that crowd the shrub.

Key Differences

Deadheading is light maintenance for aesthetics and extended blooming, while pruning is a deeper intervention to promote growth and manage the plant’s structure. Together, these practices keep your hydrangeas thriving and looking their best.

Planting a hydrangea tree is a beautiful way to enhance your garden with vibrant color and charm. Known for their large, showy blooms, hydrangea trees can serve as stunning focal points that provide long-lasting beauty throughout the growing season. Unlike naturally occurring trees, hydrangea trees are carefully trained from shrubs over several years to take on their tree-like form. This process gives them their unique, elegant appearance while retaining the lush, colorful flowers hydrangeas are famous for. However, planting and caring for your hydrangea tree properly is essential to ensure its long-term health and abundant blooms.

Choose the Right Hydrangea Tree

Before you start digging, selecting the right hydrangea tree is the first step toward a thriving garden. Hydrangea trees, also known as tree-form hydrangeas, typically come from varieties like the Panicle Hydrangea (Hydrangea paniculata). Popular choices include the Quick Fire and Limelight hydrangeas, which are prized for their large, cone-shaped blooms. Consider the size and shape of the mature tree, as some can grow up to 15 feet tall and wide. You’ll also want to think about bloom color—many varieties change color as they mature, offering dynamic interest throughout the season. For the Chicagoland area, cold-hardy varieties are essential, as they’ll better withstand harsh winters.

Select the Best Planting Location

After selecting the perfect hydrangea tree for your garden, the next step is finding the ideal spot to plant it. Location plays a big role in how well your hydrangea tree will grow and bloom, so it’s important to consider factors like sunlight, soil, and space. These trees thrive in spots with morning sun and afternoon shade. Too much direct sunlight can scorch the leaves and blooms, while too much shade may reduce flowering. Look for a place with well-drained soil, as hydrangeas don’t like sitting in waterlogged ground. If your soil is heavy clay or overly sandy, consider amending it with compost to improve drainage and nutrient retention. Hydrangea trees also need space to grow, so plant them at least 5-10 feet away from other trees, shrubs, or structures.

Prepare the Soil

Once you’ve found the future home of your hydrangea tree, you’ll need to take a look at the current state of your soil. A well-prepared planting bed is key to supporting a hydrangea tree’s roots and long-term success. Hydrangeas prefer well-draining soil that’s rich in organic matter. If your garden soil tends to be heavy or clay-like, work in compost or other organic matter to improve its texture and drainage. For sandy soils, adding organic material will help retain moisture and provide nutrients. Loosen the soil to the approximate depth of the container of your hydrangea tree to give the roots plenty of room to establish themselves. This simple step will create a healthy foundation, ensuring your hydrangea tree grows strong and produces beautiful blooms year after year.

Follow the Spacing and Depth Guidelines

Now that your soil is prepped, it’s time to start digging. Proper spacing and planting depth are critical for the health and growth of your hydrangea tree. Make sure to plant your tree at the same depth it was in the nursery pot, ensuring the root ball sits level with the surrounding soil. Planting too deeply can lead to poor root development, while planting too shallowly may expose roots to drying out. When it comes to spacing, allow at least 5-10 feet between your hydrangea tree and other plants or structures. This gives the tree room to spread and ensures good air circulation, which helps prevent disease and promotes healthy growth.

Watering Tips for Hydrangeas

One important aspect of hydrangea care is maintaining consistent moisture, but without overwatering. To keep your hydrangea tree healthy, water deeply once or twice a week, depending on rainfall and temperature. Ensure the soil stays evenly moist but not waterlogged. A good rule of thumb is to water when the top inch of soil feels dry to the touch. During hot or dry spells, your hydrangea may need extra hydration, especially in its first year as it establishes strong roots. Mulching around the base of the tree can help retain soil moisture and reduce the need for frequent watering. Avoid overhead watering to reduce the risk of fungal issues on the leaves.

Mulching

Mulching is an important step to conserve moisture and regulate soil temperature. Apply a 2-3 inch layer of organic mulch, such as shredded bark or compost, around the base of your hydrangea tree. Keep the mulch a few inches away from the trunk to prevent rot. Mulch helps retain moisture, suppress weeds, and protect the roots from temperature extremes, especially during winter months

Pruning

Pruning your hydrangea tree encourages healthy growth and more vibrant blooms. Panicle hydrangeas, like the Quick Fire or Limelight varieties, bloom on new wood, so it’s best to prune in late winter or early spring before new growth appears. Remove dead, damaged, or crossing branches, and shape the tree as needed. This keeps the tree looking tidy and promotes better air circulation, which reduces the risk of disease.

Fertilizing

In addition to regular feeding, consider applying a specialized hydrangea fertilizer in early spring to promote vibrant blooms. Hydrangeas generally don’t need excessive fertilizing, but an occasional boost—especially after the first year of planting—will help maintain strong, healthy growth. If you prefer organic options, compost or a balanced fertilizer can provide the nutrients your tree needs. Be cautious not to over-fertilize, as this can lead to fewer flowers and more foliage.

Wintering

Zone 5 winters can be tough on hydrangeas, but with the right care, your tree will make it through. In late fall, after the first frost, add an extra layer of mulch around the base of the tree to insulate the roots. If severe cold is expected, you can wrap the tree in burlap for extra protection. Avoid pruning in the late fall, as this can leave the plant vulnerable to winter damage. With proper wintering, your hydrangea will be ready to bloom again in spring!

Hydrangeas are an old-fashioned flowering shrub, often found in gardens and yards throughout the Chicago area. If you enjoy the long-lived blossoms and beautiful colors on hydrangea bushes, it’s good to know that you have many options. The team members at Platt Hill Nursery can help you find the best Zone 5 hydrangeas for your landscape garden.

Hydrangeas come in many types, from hardy mountain hydrangeas to climbing hydrangeas to the familiar big leaf hydrangeas. 

Zone 5 Hydrangea Varieties

We’ve broken this list down into different types of hydrangeas, so you can decide which varieties are best for you. If you’re having a hard time finding any of your preferred types of hydrangeas, contact Platt Hill Nursery for assistance.

Big Leaf Hydrangeas

Big leaf hydrangeas are some of the most common hydrangea types found in yards around the country. These hydrangeas feature pink, purple, blue, or mophead-style flowers depending on the soil acidity.

To change the color of the blossoms, amend the soil. In acidic soil, these hydrangeas produce blue blossoms. In alkaline soil, they produce pink blossoms. The soil throughout the Chicagoland area is very alkaline, which means you will have pink flowers without adding any amendments. If you prefer blue or lavender flowers, you will need to acidify the soil with a sulfur-based product such as Espoma’s Soil Acidifier.

These shrubs can get to be about 3 to 5 feet tall. Some of the big leaf varieties that bloom in Zone 5 include:

• Endless Summer Crush– one of our best sellers with gorgeous hot pink flowers
• Endless Summer The Original– includes pale pink flowers or if acidified a lovely sky blue.
• Endless Summer Pop Star– a new lace cap type of big leaf hydrangea that only gets about 2-3 feet tall.

Climbing Hydrangeas

Climbing hydrangeas have sticky aerial roots that can climb up to 20-30 feet tall. Climbing hydrangeas are hardy to zone 4 and produce white blossoms.

Panicle Hydrangeas

Panicle hydrangeas are the easiest of all the hydrangeas to grow; making them great for beginner gardeners. These hydrangeas are sometimes grown in a tree shape and are thus called tree hydrangeas. Panicle hydrangeas have flowers that bloom in a cluster that’s shaped like a cone, giving these shrubs an interesting visual appeal.

• Fire Light – Fire Light hydrangeas can get as large as 6 to 8 feet tall and thus need a lot of space. These easy-to-grow shrubs produce beautiful large blooms that darken to a deep reddish pink. Fire Light is so low maintenance that it’s a great shrub for someone with no time for gardening or bad luck with plants.

Mountain Hydrangeas

Mountain hydrangeas, such as the series called Tuff Stuff Hydrangeas, are a very hardy shrub that produces beautiful showy blooms in pink or purple. These hydrangeas grow in the wild in the mountainous regions of Japan and have good cold tolerance.

How to Care for Hydrangeas in Zone 5

Caring for hydrangeas is relatively easy. These shrubs don’t require a lot of maintenance, but knowing where to plant them and when to prune them is important. Hydrangeas also need consistent watering. Here’s what to know about caring for hydrangeas.

Planting Location

The amount of sunlight you have will help you decide which type of hydrangea to plant. Panicle hydrangeas prefer sunny areas which receive a minimum of 5 to 6 hours of sunlight, whereas bigleaf hydrangeas prefer cooler shadier areas, with maybe a little morning sun, but shade during the heat of the afternoon sun.

Some hydrangea varieties can grow very large (over 6 feet), and if pruned too much or at the wrong time, will not produce blooms, so it’s important to plant them where they have sufficient space to grow.

Watering Habits

All hydrangeas need to be kept properly moist.

Newly planted hydrangeas need to be watered three times weekly throughout the summer, while established hydrangeas can go longer between waterings.

Fertilizing

Fertilize your hydrangeas with a slow-release all-purpose fertilizer in early spring and again in early August.

Do hydrangeas need full sun? The hydrangea is the queen of the summer months. They are popular across Asia, Europe, and North America not only for their graceful beauty, but also for their immense flower heads and blossoms that change color throughout the summer. It can be a challenge sifting through the many varieties, so we’ve narrowed down the top five that thrive right here in the Chicagoland area.

Bobo

The Bobo blooms with an abundance of white flowers that blush pink by the end of summer and into fall. These 5-inch flower heads grace branches that grow only 3 feet tall, making it a dwarf variety. Well-adapted to our climate, it survives winters even colder than ours and thrives through our hot summers with little maintenance. It’s a member of the paniculata family of hydrangeas, which are known for their “panicles,” or cone-shaped blossoms.

Little Quick Fire

Another panicle hydrangea, its cone-shaped flowerheads open to white, before deepening to burgundy-pink like a sunset in mid- to late summer. A smaller version of the Quick Fire, it has the same early blooms but grows to a more compact size. Rising up to 3-5 feet, it’s a great choice as a thriller for a container garden or as a dainty shrub anywhere in your landscape. The Little Quick Fire is one of the most popular choices across the country.

Summer Crush

The Summer Crush is a member of the macrophylla hydrangeas, which translates from Greek as “big leaf.” Like other Bigleaf hydrangeas, it produces an abundance of rounded flowers that change color according to the soil conditions. With Summer Crush, neutral to alkaline soil produces stunning raspberry-red flowers, and acidic soil makes them bright purple. The attractive waxy coating on its leaves helps retain water in the midday heat. Its modest height and spread reach 18-36″. Most of all, the large leaves and grand flowerheads give it a look of abundance.

Strawberry Sundae

The cone-shaped flowers of the Strawberry Sundae start creamy white, before blushing to pink and then darkening to strawberry red. You’ll barely notice its small, dark green leaves beneath the abundant blooms. In mid-summer, the beautiful contrast of half-pink and half-white flowers might remind you of a strawberry sundae. They look beautiful as cut flowers, and will brighten any location in your landscape, most often reaching heights of 4-5 feet. 

Fire Light

Developed nearby in Michigan, this low-maintenance, easy-to-grow hydrangea readily thrives in our Zone 5 climate. The blooms open to crisp white, but its flower heads soon change to a blazing, pomegranate red. Its strong stems keep the heavy flowers upright at heights of 6-8′. Disease-resistant and more tolerant to droughts than most hydrangeas, the Fire Light makes a sensational hedge and enhances the beauty of any place in your garden.   The hydrangea bush is among the goddesses of the flower world, and are as tough as they are beautiful. Though they have a few particular preferences, like moist soil and shelter from the afternoon sun, the popular varieties listed here are hardy and easy to maintain. With a little seasonal pruning, you’ll be rewarded with masses of exquisite flowers that bloom right through the summer. We’d love to help you bring these beauties into your landscape.
