Latest time to prune this year?
Greetings. Should all my vines be pruned by now given the continuing cold temps? Also. I've chosen what I guess is called bilateral spur pruning. Is there an ideal pruning method for the Frontenac grape or is it dependent on factors specific to each vineyard? Thanks in advance. Chris Sheehan
Frontenac should be pruned the same way other grapes are pruned. The ideal time is just before bud break, so you have a bit of a wait. Frontenac is late to bud.
