I have a couple of grapevines that were planted 3 years ago.
The first year, they didn't do much.
The second year, there was lots of growth, but only a couple of grapes.
This year, I pruned it back quite a bit (I have 3 vines in an 8' garden) but each of the vines has 3-6 shoots coming right out of the ground. Should I trim these off now, or wait until fall?
