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 month do you cut hydrangeas back?
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.
How far back should I cut my hydrangea bushes?
To control the size and shape of this hydrangea, cut back the stems by no more than one-third of their height after the final flush of flowers finishes blooming.
What happens if you don’t cut back hydrangeas?

Should I cut off dead hydrangea blooms?
Removing Spent Blooms on Hydrangea The method for deadheading hydrangea blooms depends upon the time of year. If it’s before August, you should cut the spent blooms with a long stem attached. If it’s August or later, the plant is likely growing new buds along the stems in preparation for the following spring.
Should you cut back hydrangeas in the spring?
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. Plants that are pruned at this time are at a greater risk of winter injury because new growth at the site of wounds is more susceptible to extreme cold.
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.
Can you cut hydrangeas down to the ground in the fall?
It is easy to grow these hydrangeas because they bloom every year regardless of how they are cared for or treated. They can be pruned to the ground in the fall and they will emerge in the spring with bountiful blooms. Trim out dead and crossing stems and prune to shape the plant.
Why are hydrangea leaves turning brown?
All hydrangeas will turn brown if they wilt too many times in hot weather. Water these shrubs deeply every few days in the heat of the summer (note that hand watering isn’t deep enough) and mulch around plants to hold moisture in the soil longer.
What month is late winter?
When is Late Winter? Late winter is 4 to 6 weeks before spring thaw begins. This could be any time in January to May, depending on your climate.
How do you take care of hydrangeas in the spring?
Deeply water 3 times a week to encourage root growth. Bigleaf and smooth hydrangeas require more water, but all varieties benefit from consistent moisture. Use a soaker hose to water deeply and keep moisture off the flowers and leaves. Watering in the morning will help prevent hydrangeas from wilting during hot days.
Will hydrangeas rebloom if deadheaded?
They will not rebloom, but deadheading will clean up the plant and make way for the next year’s fresh flowers.
How do I know if I have old wood or new wood hydrangeas?
Stems that develop during the present season are known as new wood. Many hydrangeas and summer blooming spirea bloom on new growth. Trim new wood bloomers in late winter or early spring before blooming to encourage growth.
Does cutting hydrangeas promote more flowers?
Dull flowers can make your plant look blah, but pruning them away will allow for new growth. When you cut away old blooms, you encourage your plant to produce more blooms. Faded or wilting flowers can be pruned at any time.
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 can damage hydrangea?
Other diseases that can affect hydrangea include blister rust (Pucciniastrum hydrangea), bacterial wilt (Pseudomonas solanacearum), viruses, and virescence (caused by a phytoplasma). The blister rust fungus produces masses of orange spores on the underside of the leaves.
How do you revive hydrangeas?
Use the Boiling Water Method: Boil water and pour it into a cup. Stand the stems of the wilted hydrangeas in this water for 30 seconds. Immediately put into room temperature water (this usually means back into the arrangement). If the blooms are not too old, within a couple of hours they will have completely revived.
Which hydrangeas should not be pruned?
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.
What does a hydrangea bush look like?
