I have done small airlayers in the past, but this spring was the first for trying larger airlayers. My Lillian Stoffregen has over grown her spot and I decided to lower her top about a foot or so. These air layers have 3- 5 stems on them and with new growth pushed out this spring the airlayers are now about 2 ft tall. I used a handful of moss and the roots have now filled that handful of moss. My feeling now is the new moss root ball may not handle the air layers when I cut them. Should I add more moss now or go with it as is?
