Sealant for Graft Union


Active Member
What are ya'll using to seal graft unions? I've got some paraffin wax grafting tape I plan to use on small grafts but do I also need a liquid-type sealant underneath that? And I definitely need a liquid sealant for bigger rootstock and small scions. Has anybody used caulk?
I've used regular candle wax when I use anything. Most of the time I don't use anything and just use electrical tape to pull everything together and seal it up.
