Can you post a picture?
I did the same. I’m letting the regrowth stay. It’s hardening up and working on becoming fruit buds. A few bloomed after pruning but at the very least I already see more fruit buds. I have a lot more apples this year than ever, and I did exactly what you did here when i pruned last summer.
I have reconsidered and modified my post because it may not apply to espaliered fruit. It certainly seems to be an appropriate response for individual trees, based on my experience.
Thanks. I’m going to skip the photos because I don’t think it will help the responses! Thank you folks so much for your input.
