My butterfly bush was nicked with a weed whacker this weekend while my lovely spouse was outside taking care of the lawn. It didn't sever it or anything, but it stripped the bark on a portion of the main stem of the bush. It's only one one side, and it's about 3" long by about 1/2" wide. Is there something I should do for my plant to prevent more damage? Will it be OK? My dear spouse suggested electrical tape Is that something that could be helpful to wrap on the area that was damaged? I've never heard of this before.
Any help or ideas would be greatly appreciated.
