Removing the spent blooms triggers flowering shrubs to stop producing seeds and instead put their energy toward root and foliage development. This makes plants stronger and healthier, so by deadheading, you’ll be doing your hydrangeas a favor.
Do you cut off hydrangea blooms when they turn brown?
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.

What happens if you don’t deadhead hydrangeas?
If you do not deadhead your hydrangeas no harm will come to your plant. Whilst there will be no serious upfront effects, skipping the deadheading process could have detrimental effects in the following years, however, as your plant may not produce as many blooms or as big flowers.
Do hydrangeas need to be cut back for winter?
Cut back these shrubs in late winter before new growth begins. Because they need to grow and set buds the same year that they bloom, shrubs that flower on new wood generally start blossoming later than old-growth bloomers, beginning in midsummer and continuing until the first frost.
When to 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 happens if you don’t prune hydrangeas?
If you don’t prune hydrangeas then they can eventually resemble a tangled mass of woody stems, and the flowers will become smaller and less showy. If your hydrangeas are not blooming, lack of pruning is often a reason.
How late is too late to prune hydrangeas?
So these shrubs should be pruned immediately after their flowers fade. Conversely, if the shrub flowers on new wood (stems developed during the current season), its buds are set within the season, so the shrub should be pruned in early spring before that new growth emerges.
What happens if you cut hydrangeas to the ground?
If your oakleaf hydrangea is very old and woody, take out a few of the oldest, thickest stems all the way to the ground in the early spring to encourage some new growth. Don’t cut the entire plant to the ground, as you’ll both stress the plant and lose a whole season of blooms.
Can you cut hydrangeas back too much?
Sometimes bigleaf hydrangeas become overgrown and need to be trimmed. However, too much pruning will greatly reduce or eliminate flowering. In late summer, after the bloom period, dried flowers can be removed.
How do I make my hydrangeas bushier?
As a young plant, it is best to prune or pinch your plant in order to build a full bodied, well-branched plant. Every time you cut off the growing tip of a plant, you get twice as many branches and thus in the long-run, more flowers.
Should you deadhead hydrangea bushes?
Deadheading hydrangeas is not a crucial task, and will not damage your plant if you do not do it. In fact, many gardeners find that the dead flowerheads can provide interest in the winter garden, particularly on frosty days, and can also provide winter protection for the plant.
Should hydrangeas be cut back in the fall or spring?
Most hydrangeas are pruned in spring, their flower heads having been left on over winter to protect the buds beneath. Climbing hydrangeas are the exception to this rule – they are pruned in summer, after flowering.
Can you prune hydrangeas in October?
This can be done in the fall or any time you see a dead branch. To reduce the size of a hydrangea that blooms on new wood, cut off about one-third of each stem in late fall or early spring before it begins to leaf out. If your hydrangea blooms on old wood, prune right after it has bloomed when the flowers are fading.
Can you cut hydrangeas down to the ground in the fall?
Hydrangeas that bloom on new wood can be trimmed from fall through early spring. Smooth and peegee types are in this group and perform well whether cut to the ground, trimmed lightly or left unpruned.
