When digging a hydrangea to transplant, dig up as much of the rootball as possible. Since the roots are fibrous and form a ball filled with soil, the plant may be VERY heavy, so you might want to get some help with this. Replant the hydrangea in an area that is shaded during the afternoon.
Should I cut the old blooms off my hydrangea?
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.
Can you prune hydrangeas to control size?
I repeat that because it’s important: Hydrangeas should be pruned to improve appearance, not control size. The mature hydrangea is a shrub that cannot be made smaller. If you cut a big leaf hydrangea down one year it will replace that growth the following season.

What do I do if my hydrangea is too big?

Can I prune hydrangeas in the fall?
Pruning hydrangeas that bloom on new wood
Hydrangeas that bloom on new wood can be safely pruned in late fall once the plants have gone dormant or in early spring. Next year’s flower buds won’t be formed until late spring the same year they bloom, so there is no risk of removing the buds if you prune in fall or spring.
How do I reduce the size of my hydrangea?
Simply cut mature stems back by about 1/3. If the plant is completely out of control, cut all the stems back to about 1 1/2 feet tall. Over the course of the summer thin out the new shoots to avoid overcrowding. The second option is to prune your old-fashioned hydrangea immediately after the flowers fade in the summer.

Can you prune limelight hydrangeas to keep them small?
Limelight hydrangeas that have gotten leggy and ungainly will respond to a pruning to within 18″-24″ above grade.

A yearly pruning down to 18″-24″ results in fewer, and larger flowers.
What month do you prune Limelight hydrangeas?
Even when cold winters kill stems to the ground, Limelight bounces back with new stems and flowers. Prune Limelight back by one-third to one-half its size in late winter or early spring.
Which hydrangeas should not be cut back?
Old Wood Bloomers
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. But go ahead and gently thin or deadhead. Just remember new growth may come, but that new growth will be without blooms next season.
Should I deadhead my limelight hydrangea in the fall?
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.

Should I cut down my hydrangea 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.
How do you winterize hydrangeas?
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.
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.
