The apple trees on my trellis are already putting out a lot of growth. I was wondering when can I start to trim back this growth. Is it too early to do it now??? Should I wait till mid-summer???

if trellis culture is similar to espalier then follow the instruction from my post here
So I am looking up instructions in the American Horticultural society Pruning and Training book. They recommend 18-24" per tier, but raintree catalog has the first tier at 18" from the ground and tier 2 and 3 12" apart. I think all the retail espaliers I have seen are about like that.
Fruit production should not be a problem. First you have a spur baring apple.
From the book during summer
prune all new laterals from the main arms to 3 leaves above the basal cluster
Shorten all side-shoots…
