Smooth hydrangea, which blooms on the current year’s growth, should be pruned back by early March so the plants have plenty of time to grow stems and form flower buds. For bigleaf hydrangea, once plants are mature prune a few (no more than one-third) of the older branches to the base of the plant in early spring.

What is the best time of year to prune hydrangeas?

• The timing of pruning for hydrangeas depends on which type of hydrangea you’d like to prune. Hydrangeas that bloom on old wood should be pruned in summer before they set buds for the following year. Some people say that you can prune these hydrangeas as late as mid-August without affecting next year’s bloom,

What month do you prune hydrangeas?

Trimming should be done immediately after flowering stops in summer, but no later than August 1. Do not prune in fall, winter, or spring or you could be cutting off new buds. Tip-pruning the branches as leaves emerge in spring can encourage multiple, smaller flower heads rather than fewer larger flower heads.

What time of year should I cut back my hydrangeas?

The best time to prune these varieties is after they are done blooming in the summer, but no later than the end of July since they set their buds for next year in August and September. You can also prune out dead and crossing branches in the fall.

Do hydrangeas need to be cut back for winter?

Hydrangeas that bloom on new wood require pruning in late winter or early spring. Prune to shape, cutting back to about two feet. The pruning promotes new, sturdy growth, which provides the blooms next season.

Which hydrangeas should not be cut back?

The four species that flower on old wood— bigleaf, oakleaf, mountain, and climbing hydrangeas —may not need pruning at all, except when you are pruning to keep their size or shape in check.

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.

Should you cut back hydrangeas in the spring?

Wait until Spring to prune hydrangeas While some plants bloom on new growth, others primarily set flower buds on old wood. Regardless, it is best to wait to prune all hydrangeas until spring. In the fall, hydrangeas (and all trees and shrubs) are in the process of going dormant.

Should I cut off Brown hydrangea blooms?

Are the blooms on your hydrangea shrubs fading or turning brown? No need to worry – this is simply a sign that it’s time to remove the flowers, a process called deadheading. Removing the spent blooms triggers flowering shrubs to stop producing seeds and instead put their energy toward root and foliage development.

Will hydrangeas grow back if cut down?

Pruning New-Wood Bloomers You can take a more relaxed attitude about pruning if you have hydrangeas that set flower buds on current season wood, like panicle and smooth hydrangeas. Even if you cut canes back to ground level during dormancy, the shrubs will grow back and produce blooms in spring.

How do you prepare hydrangeas for winter?

Protect your in-ground hydrangea in winter by making a frame around the plant using stakes. Wrap chicken wire around the stakes to form a cage. Fill the cage with pine needles and/or leaves to fully insulate your plant. Oak leaves work well because they do not settle as easily as other materials.

How can I tell if my hydrangea blooms on old or new wood?

Remember buds for blooms are produced on old wood and the more old wood you remove the less floral display in the spring and summer. To rejuvenate the hydrangea, remove up to 1/3 of the older living stems down to the ground each summer.

How do hydrangeas look in winter?

Hydrangea flower heads turn dry and brown in the fall and will remain that way throughout winter if not removed. Hydrangeas also lose their leaves during fall, but the brown stalks remain upright unless pruned back.

Does cutting hydrangea flowers hurt the plant?

Hydrangeas will often grow back to their regular size, and over-trimming can result in uncontrolled growth. Prune faded or wilting flowers using pruning shears. Dull flowers can make your plant look blah, but pruning them away will allow for new growth.
