Termites in my raised garden beds.
I was moving one of my raised garden beds when I found it was infested with subterranean termites. It is a raised, supposedly cedar, which I would like to try to save. I use these for vegetable gardens and I garden organically. Is there anything I can do to save the raised bed and to prevent the spread to my other raised beds?
It is normal for termites to occur naturally in the soil. Most likely the wood is starting to break down. The wood is in contact with the soil which speeds up decay. All you can do is replace the wood or look at options for preserving the wood.
