Considering summer pruning (of watersprouts only) this year. Looking for the following benefits:
1. letting in more light into tree interior to help color fruits
2. improving air movement within the tree to help with secondary scab issues (yes, I will admit so having some issues this year!)
3. improving calcium uptake in the developing fruit.
Is #3 actually true, or am I remembering this incorrectly? I'm also looking for advice on timing - i.e. for maximum benefit, does this happen around terminal bud set (early august)? Don't want to stimulate re-growth - so that's why I want to make sure to get the timing right.
To make it worth the trouble, I'm most interested in the calcium benefit (as I've seen some calcium-deficiency issues here & there in recent years) from summer pruning..if such benefit actually exists.
