How to Prune an Endless Summer Hydrangea


Endless summer hydrangea are hardy in many parts of North America. They can survive temperatures below freezing, which makes them a favorite among many gardeners. The plants come in pink or blue varieties, depending on the type of soil they are planted in. A few small flowers will grow in limited sun, but the hydrangea does much better and produces larger blooms in full sun. Prune endless summer hydrangea to promote good health and keep the plant an ideal shape.

Step 1

Trim off spent blooms just after they die. Clip them just above the first set of leaves, underneath the bloom. This will promote new blooms to grow.

Step 2

Wait until new leaves have expanded before cutting dead stems down to the ground. This occurs in early June.

Step 3

Remove dead wood annually. Use pruning shears to cut the stems down as low as you can.

Step 4

Prune 1/3 of the endless summer hydrangea's old wood once the plant reaches 5 years old. Old wood includes stems that have been on the plant since the previous summer. Cut the branches down to the ground to rejuvenate the plant.

Step 5

Leave the endless summer hydrangea's leaves alone if you notice spots on them. The purple spots may appear in July. They are the result of a common disease that is harmless. There is no need to remove the leaves.
