Has anybody else tried this? The other day I was trying to move a shoot that was about 1 1/4" in dia. that was crossed beside another trunk. My intention was to push it over enough to get a pot around it to try an air-layer, because it had to go either way. Well guess what happened it broke off, so I cut it up The pieces were large and i knew it needed to be sealed to retain moisture. I looked all over and could not find the block of wax to melt. I did however find a can of that Flex Seal stuff, so I said what the heck Ill try it. What I did was spray some in an old jar lid, not much just enough to get a little puddle. Then took each cutting and pressed it into it to coat the top ends . Once it had dried it was sealed and the adhesion was very good. Now the cuttings are putting out leaves and look to have zero shrinkage. It might be a good pruning sealer also, cant see a cane borer going through that stuff. I think it just took the place of wax for me, besides a can would last a long long time because it really only take a small amount. Just a word of caution wear gloves that stuff is pure hell to get off your hands after it dries.
