I have a multi-trunk muscadine vine where instead of maintaining/pruning root shooters, the previous owner let them grow out of the ground from the root system. Now I have 20 trunks at the single location, where it grows up a fence trellis to a tabletop arbor.
How should I prune this to get good sweet fruit? Should I cut all but one trunk? cut half this year, half next year, etc? ... Leave them all and manage them via small sections on top of the arbor? There are actually 4 groups of multi-trunk grapes, but I didnt want to complicate it too much. Willing to experiment some but just looking for some guidance on whether it matters much which path I choose.
