Quick Answer: When Do You Prune Hydrangea Trees

Pruning in late fall or early spring before new growth begins will bring new blooms all summer. Big Leaf and Oakleaf hydrangeas should be pruned no later than early fall, otherwise you may cut off buds preventing any blooms come summer. For these types of hydrangeas, it’s best to prune immediately after flowering.

Should you cut dead flowers off hydrangea tree?

You should deadhead throughout the blooming season to keep your hydrangeas looking their beast and encourage new flower growth. This not only provides winter interest, but also ensures you don’t remove the buds that will become flowers next spring.

Can you prune hydrangeas anytime?

Generally, they are pruned in late summer, after blooming has ceased. However, some people prune them in fall while others do so in spring. As long as you do not cut any stems that have not bloomed, leaving healthy buds intact, they should be okay.

Should hydrangeas be cut back for winter?

Hydrangeas bloom either on old wood or new wood, depending on the hydrangea type. New-wood blooming hydrangeas should be cut back in late winter before new growth begins, while old-wood bloomers require pruning right after flowers fade in late summer.

What happens if you don’t prune hydrangeas?

Hydrangeas that bloom on old wood do not need pruning and are better off for it. If you leave them alone, they’ll bloom more profusely the next season. Just remember new growth may come, but that new growth will be without blooms next season.

Can I prune my tree in summer?

Answer: In general, pruning a tree when it is dormant is recommended if there are large branches to remove; that is, pruning between the time the leaves fall from the tree in the fall and the time the buds swell in the spring. However, pruning for safety reasons or minor pruning may also be done in the summer.

How far do you cut back hydrangeas in the fall?

Some hydrangeas’ branches often fall over under the weight of their blooms, especially after overhead irrigation or after a good rain. One way to alleviate this flopping is to cut the stems to a height of 18 to 24 inches to provide a sturdy framework to support new growth.

What is a hydrangea tree?

Tree hydrangeas (Hydrangea paniculata), also known as panicle hydrangeas, are a fast-growing flowering shrub with an upright growth habit. The shrub has oval, toothed, dark green leaves, and it produces cone-shaped flower panicles that stretch around 7 inches long with clusters of small, creamy white blooms.

Should I cut off Brown hydrangea leaves?

Prune off the ugliest leaves, and adjust your irrigation to keep water off the leaves. When you see leaves with brown or yellowish spots, it could be anthracnose, a much worse issue because it can kill the shrub.

When should you remove dead hydrangea blooms?

The best time to deadhead is when the first set of blooms on your hydrangeas begin to turn brown and dry. Cut the stem below the flower head and just above the first set of leaves. For reblooming types, you can deadhead again when this second set begins to fade, but only through mid-August or so.

How do you winterize a hydrangea tree?

A good way to start winterizing hydrangeas is to lay down a thick layer of mulch over their root area. Straw works well for this. For even greater protection, cover the shrub with a wire cage, or build a cage around it with strong stakes and chicken wire. Wrap burlap or insulation cloth around the cage.

How do you prepare hydrangeas for winter?

The simplest method is to mound shredded leaves or bark mulch around the base of the plant to about 12 inches or so. Put the mulch mound in place in late fall after the ground freezes and uncover plants in spring when temperatures begin to stay above freezing.

Why is my hydrangea not flowering?

The primary reasons hydrangeas don’t bloom are incorrect pruning, bud damage due to winter and/or early spring weather, location and too much fertilizer. Hydrangea varieties can be of the type that blooms on old wood, new wood or both. Old wood is the current year’s growth and new wood is next year’s (spring) growth.

What’s the difference between pruning and trimming a tree?

Pruning is used to remove unnecessary branches. Trimming, on the other hand, promotes healthy growth. Both services are performed at separate times of the year, using vastly different pieces of equipment, to provide a better aesthetic and healthier landscape.

Can you prune trees anytime?

Most routine pruning is done to remove infestation, weak, dead or diseased branches, and can be completed at any time during the year with little effect on the tree. Homeowners remove dead branches to make the tree look better and grow stronger.

Is a hydrangea tree different than a hydrangea bush?

None of the hydrangeas is a tree; they all grow in the shape of a bush. However, some can still be formed in the form of a small tree. The only type of hydrangea that is capable of such a transformation is the Hydrangea paniculata. In nurseries, these plants are grown as small trees 5-6 feet (1.5 m) tall.

How do you support a hydrangea tree?

No matter which species of hydrangea you are growing, you can stake as the stems begin to droop. Insert a strong, sturdy stake just behind the flower stem that is to be supported. Tie the hydrangea stem on the stake with a soft plant tie about 18 inches above the ground, just below a leaf.

How long do hydrangea trees live?

Lifespan. Hydrangeas are long-lived shrubs, sometimes living for up to 50 years if properly cared for. They enjoy morning sun but afternoon shade, and they need frequent watering during the growing season. Prune them in the fall after the blooms fade so they can grow on strong stems the following summer.
