Unbelievably, inappropriate trimming contributes significantly more to hydrangea blooming problems than poor plant health.
To keep foliage and plants in check for their perennials, late fall or spring pruning is a ritual for many gardeners.
But for a lot of hydrangeas, pruning in the late fall or early spring could mean the end of most or all of the flowers! Never prune early spring, winter, or late fall blooming hydrangeas like the Oakleaf, Bigleaf, Climbing, and Mountain kinds.
Unfortunately, summer blooming cultivars cause old wood to bloom the following year. You can eliminate all of the plant’s future blooms by delaying cutting them back until late fall or early spring.
Instead, after they have finished flowering in the early summer, early summer blooming hydrangeas should be trimmed back. This enables the formation of fresh growth and bloom buds. They are then prepared to start building up for large blooms by the following spring.
The “no-pruning rule” for early spring and late fall has an exception. The Smooth and Panicle hydrangea cultivars are the exception.
These two varieties of hydrangeas produce their blooms in late summer to early fall, as opposed to Oakleaf, Climbing, and Bigleaf varieties. In fact, if they bloom late in the growing season, that is the simplest method to determine whether you have either of these two types of hydrangeas.
These hydrangeas don’t bloom until the next spring on new growth wood because of how late they bloom. This means that as long as the plant has not begun to bud and grow, you can cut back your plants in late winter or early spring.
Let the plant grow till the next year if it produces new growth before you can prune it. You run the danger of removing fresh flowers for the following season after growing has started.
#2) Fertilizing -Spring Hydrangea Care
After we’ve covered pruning, it’s time to discuss fertilizer your hydrangeas. One of the most crucial activities for establishing a robust bloom cycle is fertilizing. But the actual key to success is when and how you apply it!
A hydrangea bush requires electricity twice in particular. The first is in the spring, when it starts to grow. The second is in early summer or late fall, depending on the cultivar, shortly before it starts to flower.
Spring FertilizingHow To Help Hydrangeas Bloom
Apply an all-purpose, slow-release granular fertilizer to the base of the plant in the early spring, either soon before or just as the plant emerges from its dormant state.
Use a balanced fertilizer with a nutrient range of 5-5-5 to 10-10-10 as a general guideline. The fertilizer’s levels of nitrogen (N), phosphorus (P), and potassium (K) are indicated by the three sets of numbers.
Plant color and healthy growth are both aided by nitrogen. While helping a plant produce strong fruit and flowers, phosphorus. Potassium is crucial as well since it supports healthy stems and branches and aids in the plant’s continued growth.
You are assisting with all 3 phases equally by giving them a balance in the early spring. The plant will receive a gradual flow of nutrients from this, enabling it to grow robust, healthy foliage as its blooming cycle approaches.
Late Spring / Early Summer FertilizingSpring Hydrangea Care
Your hydrangea should receive a second fertilizer application just before it starts to blossom. This nutritional intake has just one and one purpose—to boost your blossoms!
Due of this, a liquid fertilizer is recommended for this application. Why? because nutrients are delivered by liquid fertilizers quickly and easily. And your hydrangea actually requires that to have the strength it needs to carry out its bloom cycle.
The second fertilizer should be done in late spring or early summer to encourage summer blooming hydrangeas to bloom. Wait till late summer for types that bloom in the fall.
A balanced liquid fertilizer will work, but for this application, opt for one with a little more phosphorus. Why? Because the phosphorus will be used by the plants to produce larger, brighter, and more numerous flowers. Espoma makes a liquid organic fertilizer that is ideal for this.

MulchingSpring Hydrangea Care
Don’t forget the mulch, last but not least! Early spring mulching of your hydrangeas is crucial for a number of reasons.
First, it assists in maintaining a suitable and robust soil temperature. A thick layer of mulch also aids in fending off competitive weeds, which can rob the soil of vital moisture and energy.
Finally, though by no means least, mulch aids in soil moisture retention. moisture that the roots require in order to take up and assimilate the nutrients that will give the blossoms strength.
Hardwood bark, shredded hardwood, and even pine needles are all excellent options for mulch. The true secret is to start protecting your hydrangea with mulch as soon as spring arrives.
ConclusionSpring Hydrangea Care, How To Help Hydrangeas Bloom
Pruning your hydrangeas at the proper time is the first step in getting them to blossom and bloom profusely. Always remember to prune early summer blooming hydrangeas as soon as they finish blooming. Hydrangeas that bloom in the late summer or early fall should be clipped before they emerge in the spring.
Feed your hydrangeas with fuel in the early spring and just before they flower to get the most out of their flower power. In order to preserve moisture and keep competing weeds at bay, mulch your hydrangeas early.
Let’s hope your hydrangeas produce the biggest, most gorgeous blooms yet this year! Enjoy your garden! Mary and Jim
Should hydrangeas be pruned back in the spring?
Hydrangeas with mopheads and lacecaps (Hydrangea macrophylla) bloom on the growth from the previous year. They defy the generalization that shrubs that produce their flowers on the growth from the previous season should be clipped after flowering. The optimal time to prune hydrangeas is in the spring because of the way their stems are built. This is due to the stems’ cork-like, as opposed to woody, nature, which allows them to store enough moisture during the winter for this to freeze in cold temperatures. The stems and their buds may freeze if they are clipped in the fall, following flowering. The stems and their new buds will be better protected if the old flowers are left on the plant throughout the winter, until the severe frosts have passed. These buds will open as the sap begins to rise in the spring, and many of them should go on to bear blooms the following year.
What occurs if hydrangeas are not pruned?
If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.
Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.
Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.
Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.
The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.
They are very comparable to lacecap types, but smaller and with more compact leaves.
Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.
Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.
regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.
Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.
How should hydrangeas be deadheaded in the spring?
These are your macrophylla hydrangeas, also known as mophead and lacecap, which come in purple, pink, and blue. They also include hydrangeas with oak-shaped leaves. While reblooming kinds flower twice, some cultivars only bloom once per season on stems from the previous year (old wood).
The initial set of hydrangea blossoms should be deadheaded as soon as they start to turn brown and dry. Cut the stem immediately above the first set of leaves and below the flower head. When this second set starts to fade, you can deadhead once again for reblooming varieties, but only until about mid-August. Your hydrangeas will then produce buds for the flowers of the next year; you don’t want to unintentionally cut these off. After the summer has ended, dried flower heads can remain on the shrubs to add visual interest over the winter.
When ought hydrangeas to be pruned?
Depending on which group the plant belongs to, the timing and extent of pruning are determined:
Advice on Pruning for Group 1:
- As the days get shorter and the weather gets colder in the late summer and fall, buds for the following year’s blooms start to form.
- Typically, removing dead, diseased, or damaged branches is all that is required to preserve shape, size, and a healthy plant. Otherwise, gentle pruning ought to be practiced.
- In the summer, trimming should begin as soon as flowering ends, but no later than August 1. Pruning should not be done in the fall, winter, or spring because you risk removing fresh buds.
- Tip-pruning the branches in the spring as the leaves begin to appear can promote more numerous, smaller flower heads as opposed to fewer, larger flower heads.
Advice on Pruning for Group 2:
- On the growth of the current year, flower buds form.
- Early in the spring, as the leaves are starting to emerge, prune.
- Just above a node, prune branches back by half to a third.
- After that, prune any fragile or spindly branches.
- Minimal trimming encourages huge, strong bushes with many of tiny flower heads in H. arborescens. Hard pruning between 12 and 18 inches from the ground, or even all the way down, will result in fewer but larger flower heads that may flop if unsupported.
- For H. paniculata, remove the surrounding smaller wood while leaving the larger stems in order to establish a sturdy foundation.
Pruning may be connected to flower head size. Shoots will grow more vigorously and flower heads will be bigger and fewer with more rigorous trimming. Smaller but more numerous flower heads may result from less aggressive or tip pruning.
Consideration of hydrangeas’ mature size is the best piece of advise. Place them in a location where they won’t outgrow and won’t need a lot of pruning to keep them in check. Hydrangeas don’t need to be pruned precisely or often; as long as dead wood is removed, they will remain healthy and continue to develop and bloom.
Should I remove the brown blooms on my hydrangea?
Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
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.
Should hydrangeas be deadheaded?
Correctly and timely deadheading your hydrangeas only benefits these plants in the long run. Deadheading is the technique of removing wasted flowers from a plant to promote greater blooming later on, much like trimming. Professional gardener Melinda Myers notes that deadheading encourages the plant’s energy to flow into the leaves, stems, and roots (rather than developing seeds) for future growth.
According to Myers, deadheading your hydrangeas provides cosmetic advantages in addition to enhancing the future blooms. She says that many gardeners prefer the neat and tidy impression that faded blooms create to that of dried flowers left on the plant. The species of your hydrangeas will determine when and how to deadhead them, according to Myers. Here is her response to our question regarding the ideal moment and technique for harvesting finished flowers from several varieties of hydrangeas.
How are hydrangeas cared for?
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.
