We have a wild rabbit problem and similar saplings put in about 4 years
ago had the protection of rabbit fencing.

This *may* help. We had a problem with deer eating the roses, and we
tried this spray. I think it worked - there seems to be much less deer
damage now - but we only tried it late last year, so there may have been
other reasons. Worth trying, maybe, anyway?

BTW, I have absolutely no connection with this business or the product.
