This is the earliest I have ever started to prune the grapevines. The weather has just been so nice, low 60s, warm sunshine, that I thought I'd get an early start...so that I can panic later! The ground must still be cold though because the vines were not bleeding from the wounds so they are not yet drawing up water. With no rain forecast for at least a week, the wounds should dry out quite nicely (and be safe from airborne infection).
I love pruning, it never gets old for me. Making pruning decsions that determine this year's, and next year's, crop is thought provoking and an awful lot of fun.
