this is actually the case in point am so curious about. And my query is-- if an airlayer that has successfully rooted is not removed from the mother tree, will its age not be reset close to zero? I mean, when exactly will the resetting occur, upon removal from the tree?
conversely, and as an example for many who may have grown tomatoes(for our purposes, pertain to a perennial variety of tomato). As a tomato plant ages, it tends to grow roots above the soil line without having to be girdled/treated with hormones. If we cut the specimen at the main trunk below soil line, will this effectively reset the age of the above-ground tomato? This process is nothing more than a severe case of root pruning, so wondering if this act makes the air-layer reset the tomato’s age.
now, with peach/plum trees, if we hypothetically infect them with borers at the trunk below soil level and effectively cause root pruning(but not so much to cause death). Admittedly this sounds philosophical(and i hope you don’t find it condescending an argument), but this effectively translates to the tomato analogy, and curious if this would trigger resetting the age of the trees. Would the trees now be ‘younger’ than they were prior to the borer damage?
and lastly, the bare-root trees we receive from nurseries pretty much have the same circumstances due to severe root pruning.
