Bigleaf hydrangeas (Hydrangea macrophylla) set flower buds on old wood, which develop in late summer and fall; therefore, pruning should be done immediately after flowering. Be sure to remove only a third of the total growth of the plant. The cultivars in the Endless Summer® series are an exception to this rule.
How do you prune hydrangeas in SC?
For dormant pruning, remove dead stems and flowers in early spring, just as buds begin to swell. Remove any branches or branch tips that don’t show swelling buds, but leave healthy buds in place to preserve the future flowers they contain. If you need to reduce plant size, prune just after the blooms have faded.
What month do you cut back hydrangeas?
The structure of hydrangea stems means that it’s best to leave cutting back until spring. This is because the stems are cork-like, rather than woody, and hold enough moisture inside them during winter for this to freeze in frosty weather.
How and when should hydrangeas be pruned?
Prune back stems to just above a fat bud — called a heading cut — in fall, late winter or spring. These plants have conical-shaped flower heads. I recommend leaving the dry, tan flower heads on the plant to provide some winter interest in your landscape, so I wait to prune these until late winter or spring.
How far back should I cut my hydrangea bushes?
To rejuvenate the hydrangea, remove up to 1/3 of the older living stems down to the ground each summer. This will revitalize the plant. If necessary to control the size of the plant, cut back before late July to allow for buds to develop. Usually the plant will return immediately to its former size.
When should hydrangeas be pruned in South Carolina?
The panicle (Hydrangea paniculata) and smooth hydrangeas (Hydrangea arborescens) develop flowers on new wood produced during the current growing season. Since they develop flowers on new growth, they can be pruned either in late winter or early spring while the plants are dormant and before new growth begins.
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.
Should I cut off dead hydrangea blooms?
You should deadhead throughout the blooming season to keep your hydrangeas looking their beast and encourage new flower growth. However, stop deadheading hydrangea shrubs in mid to late fall, leaving any spent blooms in place.
Should hydrangeas be cut back for winter?
Tip. 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.
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.
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.
