I have a crape myrtle that I attempted to transplant last spring. Unfortunately, it didn't do so well (I damaged more of the roots than I intended), and while it did leaf out last year, after a long cold winter I thought for sure it was dead.
But, to my surprise, around June of this year, it started to leaf out just a little, and we even got some flowers! I've trimmed off all the dead wood (which, unfortunately, was most of the plant), and I'm hoping and praying for the best.
It occurred to me that every pruning wound, or place that I cut off deadwood, is a potential avenue for bugs or pathogens to invade the plant, which would be bad news in its already weakened state. Is it a good idea to seal off the ends somehow? If so, with what? I have a wax sealant intended for use on hardwood decking. Is that, or another product, a good idea?
