Hydrangeas in North America are classified into five types: bigleaf, mountain, smooth, panicle, and oakleaf. Some form their flower buds on old wood, indicating that next summer’s buds are already there. To ensure your hydrangea bushes are ready for spectacular flowering, master the art of pruning. Hydrangea macrophylla, aspera, serrata, and quercifolia can be lightly pruned by cutting back the old flower. Smooth Hydrangeas should be pruned in late winter/early spring, and they can be cut down to the ground if desired.
For larger blooms, consider cutting your hydrangea back to the ground in early spring. If your bush looks tangled, you can rejuvenate it by cutting it back to the ground. Climbing Hydrangea can tolerate heavy pruning, which should be done in early spring around March before it leaves out. Cut back unwanted branches to a main stem, and prune last year’s growth back to a healthy framework between 30cm and 60cm high.
To reduce plant size, cut down all stems to the ground in late winter or early spring, prior to new stem growth. Wait for bigleaf hydrangeas until new growth appears in the spring, making pruning cuts one quarter inch above the first set of live buds. If frost damage occurs, prune back affected shoots to just above the first undamaged pair of buds on healthy wood.
Hydrophus that bloom on new wood can be safely pruned in late fall once the plants have gone dormant or in early spring. Shrubs that bloom on new growth should be pruned in dormancy in late winter or early spring just before the critical new growth has started.

What is the best month to prune hydrangeas?
Hydrangeas are typically pruned in late winter or early spring, with climbing hydrangeas being pruned after flowering in summer. Hydrangeas bloom from mid- to late summer, while mophead and lacecap hydrangeas bloom satisfactorily with little attention. Annual pruning encourages new growth and better flowering display. Other species, including climbing hydrangeas, benefit from a trim. Timing is usually late winter/early spring, but sometimes late summer. Pruning hydrangeas can be easy to moderate.
Where should I cut my hydrangeas?
Hydrangea paniculata, also known as panicle hydrangea, is a plant with conical-shaped flower heads that provide winter interest. It is best to prune back stems to just above a fat bud, called a heading cut, in fall, late winter, or spring. Quick Fire®, Limelight, and First Editions® Berry White® are plants that produce buds in late summer to early fall, so they should be pruned after they finish blooming and before August.
Can you split hydrangeas in the spring?
Splitting hydrangeas is crucial, especially in early spring or fall, as new growth is emerging and the plant is dormant. Avoid dividing in summer as it can cause stress and increase susceptibility to disease and pests. The best hydrangea varieties to split are big leaf, oakleaf, and smooth, as they tend to be more resistant to division. It’s important to note that not all hydrangeas can be propagated by division.
Should hydrangeas be cut back in the spring?
The pruning of hydrangeas in New Hampshire is best done in spring, as they are in the process of going dormant and producing little new growth. This time is also at a higher risk of winter injury due to the vulnerability of new growth at the site of wounds. Additionally, fall pruning can reduce the number of flowers the following summer.
The bigleaf hydrangeas, commonly grown in New Hampshire, develop their flowers at the tips of stems on old wood from the previous year. If these buds are killed or damaged during winter, the hydrangea’s flowering potential is reduced. To prune these plants, make pruning cuts one quarter inch above the first set of live buds, and cut dead stems flush to the base.
The other common hydrangea species in New Hampshire, such as smooth, panicle, and oakleaf, also bloom on new growth. To improve the overall plant structure and habit, remove spent flowers and prune the plants in late winter and early spring before leaf emergence.
Where do you cut the stem of a hydrangea?
To facilitate the opening of the hydrangea’s vascular system and enhance water consumption, it is recommended to make an angled cut on the stem and vertically up the branch a few inches, ensuring the immediate placement of the stems.
What is the mistake for pruning hydrangeas?
Pruning hydrangeas is best done in late winter and early spring, making it a good weekend job during March. Pruning after winter frosts protects the plant from winter injury. Climbing hydrangeas should be left until early summer, as they produce flowers on old wood. Pruning too early may remove new buds before they bloom. Tom’s Guide offers expert editors to keep you informed and prepared for the prime growing season by pruning your hydrangeas at the right time.
Should hydrangeas be cut all the way back?
To prune hydrangeas, start in early spring by cutting back last year’s growth to a healthy framework between 30cm and 60cm high. Prune to just above a pair of healthy buds on each stem, and cut back to the lowest healthy buds for big flowers or less hard for a natural look or taller plant. Climbing hydrangeas like Hydrangea anomola subsp. petiolaris and Hydrangea seemannii should not be pruned until after flowering.
When should I cut the head off hydrangeas?
Pruning hydrangeas is typically done in late winter or spring, except for climbing hydrangeas which are pruned in summer. Different types of hydrangea require different pruning techniques. To identify the type of hydrangea, wait for its summer flowering and prune it the following year. If unsure, leave it unpruned for a year. The following list shows the most common types of hydrangea found in gardens:
How do you wake up hydrangeas in the spring?
Hydrangeas can be revived by submerging them in water and allowing them to sit for a few hours to rehydrate. This method won’t bring other cut flowers back from the brink, such as roses, peonies, or tulips. If you’ve ever built a beautiful bouquet only to have the hydrangeas wilt before the other blooms, learn how to revive them to extend their life. Hydrangeas are often the first flowers to start looking sad in an arrangement due to their thick, woody stems that produce a sticky sap.
However, they can draw moisture in through their florets, making it possible to perk up wilted blooms. This trick can help extend the life of your hydrangeas and allow them to continue enjoying them for a few more days.
Should I cut the dead flowers off my hydrangea?
While deadheading is beneficial for plants, it should be discontinued in mid to late fall to allow the blooms to remain intact throughout the winter season.
What happens if I forget to prune my hydrangea?
If you forget to prune your hydrangeas for a year, they may grow too big, tangled, or have smaller, less showy flowers. To restore their beautiful shape, you can use proper pruning techniques, such as using sharp secateurs. Felco secateurs are a good choice, and even good secateurs can become blunt after a season, so sharpening them with a sharpening stone can help maintain their strength. Remember to use a good pair of secateurs for optimal results.
