Hydrangea tree care

Pruning in late fall or early spring before new growth begins will bring new blooms all summer. Big Leaf and Oakleaf hydrangeas should be pruned no later than early fall, otherwise you may cut off buds preventing any blooms come summer.

Should I cut dead flowers off hydrangea tree?

When you deadhead hydrangeas, you aren't harming the plants at all. 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.

How do you winterize a hydrangea tree?

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.

How far back can you cut a hydrangea tree?

Cut these stems close to the ground. 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.
