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
Are hydrangeas pruned in the spring?
Pruning is not typically thought of as one of the many gardening activities that may be done in the fall, despite the fact that there are several. It can be difficult to cultivate hydrangeas successfully in New Hampshire, and if you want your plants to blossom, there is frequently very little room for error in pruning.
Wait until Spring to prune hydrangeas
In New Hampshire, hydrangeas come in a variety of kinds, and each one has quite distinct growth patterns and pruning needs. Some plants only produce flowers on fresh growth, while others mostly produce flower buds on older wood. In any case, it is better to postpone all hydrangea pruning until spring. Hydrangeas, as with all other trees and shrubs, go dormant in the fall. Not much new growth is produced by them until the next spring. As new growth is more vulnerable to harsh cold at the location of wounds, plants that have been trimmed now run a higher risk of winter damage. Additionally, fall pruning may lessen the quantity of June blooms.
Considerations for pruning hydrangea species commonly grown in New Hampshire gardens
The gigantic blue mopheads or lacecaps known as bigleaf hydrangeas (Hydrangea macrophylla), which are familiar to most gardeners, form their flower heads at the tips of stems on old wood from the previous year. Although lower buds along the stem have the capacity to grow blooms as well, the hydrangea’s blossoming potential is decreased if those buds are died or damaged throughout the winter. Wait until new growth sprouts in the spring before pruning your bigleaf hydrangeas. Approximately 1/4 inch above the first group of live buds, prune the plant. A hint: the interior of living stems will be green, whereas the interior of dead stems will be brown. Cut completely dead stems flush with the base.
The three other hydrangea species that are frequently planted in Fresh Hampshire—oakleaf (H. quercifolia), panicle (H. paniculata), and smooth—all bloom on new growth. Before the emergence of the leaves in the late winter and early spring, remove wasted flowers and prune the plant to improve its general structure and habit.
In conclusion, there are a ton of other activities you can engage in to stay occupied in the garden during fall. Save the spring for hydrangea pruning.
In the spring, what should I do with my hydrangeas?
You can prune hydrangeas paniculata and aborescens more severely without losing this year’s blossoms because they bloom on new wood. Although pruning is not necessary, if it is not done the plant will grow taller, with the majority of its flowers at the top.
Cut back to a healthy framework
Trim the previous year’s growth back to a strong framework that is between 30 cm and 60 cm high in the early spring. On each stem, prune to just above a pair of sound buds. For large flowers, prune back to the lowest healthy buds; less firmly for a more natural appearance or a higher plant.
Watch Monty Don describe the many hydrangea trimming techniques in spring:
In the spring, should I remove the dried-out blossoms from 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.
When ought hydrangeas to be pruned?
Depending on which group the plant belongs to, the timing and extent of pruning are determined:
Pruning Advice 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.
What occurs if your hydrangeas aren’t 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.
Where are hydrangeas cut?
Mophead hydrangeas and lacecap hydrangeas, commonly known as bigleaf hydrangeas (Hydrangea macrophylla), are pruned using the same technique.
With its broad, roundish heads of huge petals in colours of blue, pink, green, and white, mophead hydrangeas are a popular choice for gardens. They are therefore a popular shrub option for cottage garden ideas and are also effective shade-giving bushes.
Small blooms in the center of the bloom and a border of bigger petals on the outside help identify lacecap hydrangeas.
The experts at Thompson & Morgan suggest that in order to winterize hydrangeas, “it’s better to leave the faded blooms in place over the winter to safeguard vulnerable new buds from frost damage.”
Early in the spring, while pruning lacecaps and mophead hydrangeas:
- To promote new growth that will produce better blooms, remove one or two of the plant’s oldest, weakest stems at the base.
- Just above a pair of buds, carefully remove any old flowerheads using secateurs.
- Don’t remove any of the blossom buds, please.
- Cut the stems down to the plant’s root system if the bigleaf hydrangea shrub has been neglected and has a lot of overlapping, tangled branches. The hydrangea won’t blossom until the next year, though.
