Hi- I have a Spirea bush in my front yard that is looking rough. A couple years ago it was beautiful and bushy! I noticed in mid Summer that one of the middle branches (that had full leaves) was starting to dry up and die. It would literally be a twig in the middle of the bush, so I cut it out. A week later, a new branch would wilt, dry up and become a twig. I have slowly been cutting out the branches as this happens and now the center half of the bush is gone! What is causing this? I have tried spraying for bugs (I do this a couple times a year- the sister Spirea next to it always seems to become infested). Otherwise, the ground soil looks healthy as does the rest of the outside branches!

Hi and welcome to NGA!

From what you are describing it sounds like you might have Fire Blight - a bacterial disease. Do the dead/dying branches look scorched? If you can post a picture of the whole bush plus a closeup of one of the branches that would help us zero in on the problem. Also you want to thoroughly clean your clippers with alcohol after cutting away dead material.

Here is a link that covers problems specifically for Spirea.

I'm thinking that's what it is. Your best bet would be to call your local county extension office as they can give you information specific to your location. Here is a link - it looks like the person you want to talk to is Amy Lentz. You can actually send her an email with pictures attached.
