My point continues to be that we are now talking about two different things. You started with a picture which looked like a method used for apple and pear espaliers to create short fruiting spurs. These other systems you keep providing links to are about methods now used to allow mechanical pruning or at least fill in acres of producing trees sooner. Training is different than how you manage spurs and peaches are not a species in which spurs are a matter of discussion, to my knowledge.
Of course you can train peaches into various scaffold structures and even use the trunk as a single scaffold, but the crop comes from shoots that grew the previous year. The only stub cutting I do for shoots the following year is when trees donât give me enough fresh shoots down the extension of a scaffold and I will sometimes make a short stub of an excessively vigorous annual shoot (water sprout) which will often produce a short shoot the following season. I also cut back annual shoots sometimes to reduce the thinning requirement, which is a common practice. I donât even think of that as stub cutting on peaches because the consequences are much different than with other species- it doesnât creates excessive vigor because the shoot puts most of its energy into producing fruit. Pears and apples donât usually have flower buds along the length of annual shoots to focus energy on. Only tip bearers do.
I also will take water sprouts and bend them close to horizontal with older peach trees whose vigor has slowed so much that I have to make use of such shoots to keep the trees productive. Unlike commercial orchards around here, the home orchards I manage donât need max productivity and my customers like to keep trees alive much longer than would be commercially acceptable in terms of tons per acre.
