more success rooting hybrid Japanese / American plum variety Toka

more success rooting hybrid Japanese / American plum variety Toka. cuttings at 4-5 weeks had callous dipped again in 0.4% IBA and restuck in groups, what I’m starting to consider renovating a tray, added bottom heat for the first time this season. Rooting response has been good, the bottom heat is enough that the medium feels warm. Wondering if any cuttings that take more than 4 weeks = should use stronger hormone and bottom heat. Slowest rooting cuttings I have under mist currently are a few types of prunus, cottoneaster and lilacs. Everything else rooted and has been moved out. This time of year also has an effect, in July species that would root heavily in two weeks are now taking four. Next year I’ll try these Toka cuttings in June and see how they root with 0.8% iba and bottom heat. I think this process can work with Malus, I had some success last year with baccata and those are all going into a stoolbed this fall. It’s fun to consider that these fruit trees aren’t propagated by softwood simply because it’s either been decided it’s not worth the difficulty, or if you have overcome that aspect there isn’t a strong commercial application - a commercial orchard will always use rootstocks. But for the hobbyist, it opens up new possibility for an own root variety of a cultivar which could potentially live longer, grow larger and be more hardy. At minimum if winter kills the top it’s going to regrow true to type. #propagation
