Knowing exactly when it’s the right time to prune your grape vines is pretty important. I thought I had my timing right when I pruned a few branches right before Spring was officially here, but evidently it was too late in the season to do so. I didn’t figure it would matter much either way if I only chopped off three little vines. Boy was I wrong.
Experts recommend that you do your pruning in Fall or early Winter, when all of the leaves have fallen from the plant. During dormancy the sap in the vines is at a low level, and bleeding is less likely to occur. When it starts to get close to Spring (even mid to late winter), the sap begins to rise again, delivering water and sugar to the growing leaf buds. If you prune during this time, you are disrupting the flow of the sap and the result is dripping vines. Like mine.
Now I know. Only prune in Fall and early Winter. Even if it’s only one little branch.
I keep watching it every day to see if it has stopped dripping yet. I’ll be glad when it does!
