It’s that time of year when the Hydrangeas leaftier moth caterpillar shows up on smooth aborescens hydrangeas. You may notice two leaves sticking together like a pocket. The damage is more aesthetic than anything and does not impact the health of smooth hydrangea but can damage the flowers. If you see this, clip off the affected leaves, crush them with your heel, bag, and throw away.

It is time to cut out the dead sticks on your Macrophylla Mophead hydrangeas. Here on the coast of Massachusetts, we had a mid April frost that killed many of the developing flower buds. If they didn’t open up with the last few days of heat, they are dead. Therefore cut out the dead wood to the ground and cut any dead tips down to the first set of leaves. If you have a type that only flowers on old wood, such as Nikko Blue, you may not get any blooms this year. Rebloomers will bloom a little later on the new wood.
