Although the hydrangea’s leaves and flowers seem delicate, little careful care is actually needed for them. Everything you need to know about caring for hydrangeas is provided in these recommendations.
- Over the course of the growing season, water at a rate of 1 inch per week. To promote root growth, deeply water three times each week. All varieties of hydrangeas benefit from constant moisture, but bigleaf and smooth hydrangeas need more water. To water thoroughly while keeping moisture off the flowers and leaves, use a soaker hose. Hydrangeas won’t wilt as much if they are watered early in the day on hot days.
- To keep the soil around your hydrangeas cool and moist, add mulch. Over time, an organic mulch decomposes, supplying nutrients and enhancing soil texture.
- Apply fertilizer according to the type of hydrangeas you have. Every variety has varied requirements and will profit from applying fertilizer at various times. A soil test is the most effective tool for determining your fertility requirements.
- In March, May, and June, bigleaf hydrangeas require numerous mild fertilizer applications.
- Two applications in April and June work best for oakleaf and panicle hydrangeas.
- The only time smooth hydrangea plants require fertilizing is in the late winter.
- By selecting cultivars with resistant characteristics, you can avoid pests and diseases. Hydrangeas can have leaf spots, bight, wilt, and powdery mildew. Although they are uncommon on hydrangeas, pests might arise when the plants are under stress. Aphids, leaf tiers, and red spider mites are examples of potential pests. Your best line of defense is to properly care for hydrangeas.
Do you regularly water your hydrangeas?
To help maintain moisture when planting in a container outside, choose a light-colored ceramic pot. Dark colors heat up more quickly. Make sure a drainage hole is present! At least three times every week, the hydrangea needs to be thoroughly watered. Never simply water the plant in one spot; always water it all the way around the container. The pot’s bottom ought to leak water. Never leave it submerged in water because the roots will rot away.
How can I determine whether my hydrangea needs water?
Both overwatering and underwatering can harm hydrangeas. Both may cause the plant to grow slowly and ultimately die. How then do you know when to water your hydrangeas?
Checking the soil around your hydrangea should be the first step. Check to see if the soil is still moist by sticking your finger four inches into the ground (approximately to the knuckle of your pointer finger). It’s time to water if the soil is dry.
Because hydrangeas might appear wilted in the heat of the day even though the ground is still wet, it is preferable to inspect the ground rather than relying solely on looks. However, if your hydrangeas appear wilted early in the day before it gets hot or later in the day as the temperature starts to drop, this is a sign that they need water.
Check the soil to differentiate between Hydrangeas that have been under- or over-watered if you see brown leaves. Overwatering is the problem if your soil is always wet; if it’s dry, you probably have the reverse issue. Instead of attempting to interpret your Hydrangeas’ appearance, check the soil.
Can I water my hydrangeas in the morning or at night?
The slight shade that hydrangeas prefer will prevent them from withering. If your plant is in direct sunlight, it could need additional water to prevent wilting.
Early morning or late evening are the optimum times of day to water hydrangeas so that the moisture won’t quickly evaporate in the heat of the day. Because it provides water directly to the plant’s base, where the roots can quickly absorb it, hydrangea drip irrigation is an efficient method of giving the bushes an even distribution of hydration.
Hydrangeas require enough water, especially those with large, meaty leaves, but Oregon State Extension advises against giving them “wet feet.” If your hydrangea is losing leaves or if the edges of its leaves are brown, your bush is likely receiving too much water. If you water your hydrangea and then see that the wilted leaves return back to life, your hydrangea was thirsty.
A hydrangea can you overwater it?
Hydrangea overwatering has a variety of effects on leaf growth. Instead of dark, lush green leaves, overwatering-induced root rot results in yellowed leaves. An overwatered plant may drop leaves early or exhibit an appearance of excessive green foliage as a result of stifled bloom development. Additionally, excessively big leaves may block opportunities for budding.
When do hydrangeas bloom?
The type, cultivar, planting zone, and hydrangea blooming season all affect when they bloom. The majority of hydrangeas with new growth form buds in the early summer in preparation for blooming the next spring, summer, and early fall. Hydrangeas may stop flowering in the heat of the summer in hot locations, but they will blossom again in the fall.
How do you cut back hydrangeas?
Hydrangea plants don’t require pruning if they are allowed plenty of room to develop in the garden. Only the periodic clearance of dead wood is necessary.
Do you need to deadhead hydrangeas?
Your hydrangeas will continue to bloom into the fall if you deadhead them. Hydrangeas make wonderful cut flowers, so there’s no need to wait until the flower wilts. Leave the early fall blossoms alone so they can fade naturally. In the days leading up to your freeze date, you don’t want to promote new growth.
How do you control hydrangea color?
The distinction of hydrangeas is that you can modify their color. But keep in mind that not all hydrangea varieties can change their color. H. macrophylla, a species of bigleaf hydrangea, responds to changes in soil pH. Hydrangeas can absorb aluminum thanks to a low soil pH, which gives the blossoms a lovely blue hue. Reduce the pH of your soil by mixing in sulfur or peat moss to enhance the number of blue hydrangea flowers. Throughout the growth season, you can keep amending your soil with extra aluminum sulfate. When you add ground limestone to boost the pH, pink and red blooms shine.
You may precisely modify your hydrangea color using a soil pH test. To avoid the plant from being harmed, keep the pH level below 7.5. In the fall, all hydrangeas will naturally fade regardless of the modifications you’ve made. Don’t worry, the plant will display vibrant, new blossoms once more in the spring.
Can hydrangeas grow in shade?
Although they won’t blossom in complete shade, hydrangeas prefer dappled or infrequent shade. How much sun do hydrangeas need is more important to consider than whether they love the sun or the shade. Your hydrangeas require more sunlight the further north in your garden you are. A general guideline is six hours of sunlight each day. However, southern hydrangeas can thrive with just three hours of sunlight per day.
Can hydrangeas grow in full sun?
While hydrangeas prefer morning sun, they struggle in the hot, afternoon sun. For these gorgeous creatures, partial shade in the later hours of the day is optimal.
Can you grow hydrangeas in pots?
Even if you don’t have enough room in your garden to cultivate hydrangeas, you can still enjoy these lovely blossoms by learning how to grow hydrangea in a pot. As long as you follow the fundamentals of caring for hydrangeas, the procedure is rather straightforward. Select a pot with at least an 18-inch diameter to accommodate the mature size of the particular hydrangea you are growing. In order to maintain the constant moisture level that hydrangeas demand, look for non-porous containers. Excess water will be able to adequately drain thanks to drainage holes. Consider growing dwarf hydrangeas like Buttons ‘n Bows, Mini Penny, and Little Lime.
How do you keep hydrangeas from wilting?
Morning irrigation on a regular basis can assist stop withering. Some hydrangea cultivars simply can’t stand the heat. No matter how much water you give them, they will begin to wilt in the afternoon heat. Mulch applied in layers can help soil retain moisture and stay cool. You shouldn’t be concerned if your hydrangeas bloom again once the day cools. A little midday wilting is preferable to overwatering and drowning your hydrangeas.
How long do hydrangeas need to be moist?
The spectacular, huge hydrangea blossoms come in a wide range of hues, including blue, red, purple, white, and pale green. You’ll be relieved to learn how simple it is to dry the blooms if you cultivate hydrangeas and wish to keep their beauty for a long time after they bloom. One type of flower that requires absolutely no work to keep is the hydrangea; it dries in about two weeks and can last for up to a year.
There are numerous techniques to preserve hydrangeas, but water-drying is the best because it keeps the flowers’ shape and color.
Do you remove dead hydrangea branches?
Remove stems that are crossing or dead. Cut these stems just above the soil line. Keep in mind that old wood is where buds for blooms are generated, thus the more old wood you remove, the less blossoms will appear in the spring and summer. Remove up to one-third of the older living stems from the hydrangea each summer, cutting them all the way to the ground.
Why are the leaves on my hydrangea curling and becoming brown?
The main cause of browning hydrangea leaves and flowers is typically excessive moisture loss from the leaves, which is greater than what the roots can absorb. Excessive wind dries out the leaves, causing them to curl and turn brown. Flowers and leaves turn brown when there is not enough moisture around the roots.
The following are the most typical causes of browning hydrangea blooms and leaves:
- The soil must be continually moist for hydrangeas. Flowers and foliage wilt and become brown in dry soil.
- Excessive wind dehydrates plants faster than the roots can absorb it, causing the leaves to curl and turn brown.
- If the container is too tiny and dries out too rapidly, the blooms and foliage of potted hydrangeas become brown.
- Hydrangea leaves and blooms can become scorched by too much sun, giving them crispy brown in appearance.
- The edges of hydrangea leaves turn brown due to fertilizer burn.
- Spring’s developing leaves and flower buds may become brown and mushy due to a cold spell.
- Brown patches on hydrangea leaves may be caused by a leaf spot fungus brought on by overhead watering.

Should hydrangeas be misted?
You’ll need to conduct some detective work to find out why your hydrangea is drooping. Reviving your plant should be simple if the damage’s origin has been determined.
Apply mulch three to five inches deep
In the spring, mulch hydrangea. Mulching can help your plant stay warm throughout the bitterly cold winter months in addition to keeping your soil moist throughout the summer. Pine straw, chopped leaves, or wood mulch are all suggested mulching materials for hydrangeas. Around hydrangeas, pile mulch three to five inches high.
Reduce the need to water by mulching at least once a year. Mulching should maintain soil moisture and stop potential drooping brought on by dry soil and underwatering.
Enrich the soil with organic matter
The prevention of plant drooping depends on healthy soil. In rich, well-drained loam soils, hydrangeas grow nicely. To increase the amount of beneficial microorganisms in the soil, you should add organic compost or aged manure. If the soil in your yard is clay, add gypsum and give it a good stir before planting hydrangeas. A fertile soil does not need more fertilizer.
Grow hydrangea in dappled light
Hydrangeas need between four and six hours in direct sunlight each day. However, keep in mind that the plant’s leaves and flowers will suffer from exposure to direct sunshine. Growing hydrangeas in partial or full shade will prevent the plant from burning or withering.
Hydrangea will remain healthy for a very long time if you can place the plant where it receives full morning sunshine and protection from the midday sun. When your
Mist the leaves and flowers
If the leaves and blooms of your hydrangeas are wilting, you can try to solve the issue by spraying the petals once each day. In addition to their roots, hydrangeas also take up water through their stems and blossoms. If your plant is growing in an environment that is hot and dry, misting is very important.
Additionally, spraying cut hydrangeas in a bouquet will maintain their health as the leaves and flowers take in the water and restore their turgidity.
Deeply water hydrangeas three times a week
If the top one or two cm of the soil feel dry, or if the leaves start to droop, hydrangeas need water. If you see these symptoms, water the plant well three times a week, either in the morning or in the evening. Despite the fact that they prefer moist soil, be careful not to overwater and cause damp soil.
Even in hot, dry summers, regular watering will help keep the large hydrangea blossoms in place.
Apply a low release nitrogen fertilizer
If your soil lacks sufficient organic nutrients, Clemson Cooperative Extension advises using a slow-releasing fertilizer for hydrangeas. Per 100 square feet, the experts advise using two cups of a 10-10-10 fertilizer. Hydrangeas require fertilizer in March, May, and July. But a soil test must be carried out first.
Use a fertilizer with additional phosphorus and potassium if your soil is high in nitrogen to balance the soil and prevent excessive blooms and droopy leaves.
Grow in a pot of about 12 to 16 inches in diameter
Because the water evaporates so quickly in small pots, I do not advise growing hydrangea there. Perhaps the reason your hydrangea plant is withering is because you have a small pot for it. The plant can be kept strong and healthy in a sizable container with a diameter of 12 to 16 inches.
Most crucial, the pot needs drainage holes at the bottom to allow air to reach the soil and the roots of the hydrangea. Keep the plant out of standing water.

Why shouldn’t we water plants in the evenings?
Even though there is a lot of moisture, the sun can still absorb it throughout the day. However, watering at night allows the water that is sprinkled to remain for a longer period of time because there is no sun to do so. There will undoubtedly be germs and fungi as a result.
Is it acceptable to water plants at night?
The time of day, temperature, the soil, and the age of the plants are crucial elements in determining when and how often your plants need water, even if different Southern Living Plant Collection kinds have varying requirements.
The best time to water plants is in the morning or evening.
Watering the plant in the morning gets it ready for the day, and watering it in the evening gets it cool. More significantly, watering during these times actually aids in water retention for the plant. When you water a plant in the afternoon, especially in the summer, the water will evaporate rather than soak into the soil and roots of the plant because the sun and heat are at their strongest. As the plant has time to dry before the sun sets, morning watering is actually preferable to evening watering. Water tends to rest in the soil, around the roots, and on the foliage at night, which promotes insect proliferation, rot, and fungal growth.
Heat and dry soil are always indicators that a plant needs more water
Your plants are baking with you when it’s hot outside and the sun is out. Your plants agree that there is nothing better than a pleasant drink of water. The plant is already dehydrated if the soil is dry, so you should water it more frequently to promote healthy growth. The soil should ideally be both moist and well-drained.
A plant’s age also helps you know when to water
“Age” refers to both the length of the plant’s life and the amount of time it has lived in your yard. The young and newly planted plants require more water to develop a strong root system. In order to encourage root strength and expansion, shallow and delicate roots need greater water. Mature plants require more water all at once so that their established roots can flourish deep in the ground. They want less water more frequently.
It can be challenging to determine when to water because there are so many different kinds of plants, but look out for the warning signals. Your plant may be receiving too little or too much water if you notice a general decline in its health, yellowing or browning foliage, unblooming flowers, or falling petals. Most importantly, keep in mind to set aside a little additional time in the morning for thorough watering—your day can end up being healthier as a result!
