Hiya, this question is probably a little unconventional as I appreciate it is not really the ideal way to do it. However, I have a Honeysuckle ( Lonicera Graham Thomas ) planted 2 years growing up an old tree trunk, on an embankment, well established and flowering well. I have to build up the level of the soil around it by approximately 18 inches. I don’t really want to disturb it, if I can get away with making the ground up around the bare stems will not hurt it. “So” that is my question. If I bury 18 inches of the bare stems will it “layer” ie send out roots from the nodes buried or will it suffer?
