It is a tall magnificent tree, has good apples, and bears well.
I want to get some starts from it to eventually plant in my own yard. I'm thinking of active pruning to maintain an appropriate size.
What do you think about rooting cuttings from that tree directly in a soil or solution, and if it works, how long does it take and what should I expect?
If your going to root cuttings, you need to do that in the spring with new growth branches to get the best results. I like to use a 6% rooting hormone when I can't make "willow water"( the natural rooting hormone solution).
To Air layer you will need sphagnum moss and either plastic and ties or rooting cups (a commercial product that makes air layering easy peasy), again you also need some rooting hormone either powder or solution.
Either of these methods will be perfect for a wild tree. Grafts (unless you have done them before) can be tricky to get just right.
I learned to graft in the early 1970's, it took me ten tries to get my method just right so I never had to worry about survival of a bud or branch.
Even though I can graft with the best, I almost always opt for air layering for everything except grafted trees, those are always grafted to new root stock.
To root cuttings from this tree, get some sharp sand and pots to go with the sphagnum moss, mix the moss with the sand, this gives you a well draining, moisture holding rooting medium. slice through the bark in at least three places and apply rooting hormone powder or slice the same and soak in rooting solution for at least two hours before planting in the pot with your medium, then water in with the rooting solution and cover to keep moist. If you need more detailed info on the procedures, let me know.
