I have a lot of clients with spireas with a lot of dead wood in them. They are looking pretty bad. What is the reason for this and is there any way to prevent this? Can I cut them back to the ground in the fall?

Spireas need to be frequently watered, especially during dry spells. They are also a target of mites and a few other insects. Either, or both, could be causing your problems. Yes, you can cut them back to the ground. I frequently do this to keep them small, but I do it in the spring. Why? spireas are a favorite of praying mantis for laying their eggs.

What type of spirea? Big difference. Little princess and similar varieties as stated above. Snow fountain and snow mound are more woody can be cut low and then hand pruned as they grow back.

I've pruned back to the ground - little princess, goldflame, anthony waterer, neon flash, shirobana, and snowmound.
