I planted several grape vines last spring on a trellis. How far back should I trim them before this growing season?
This one is my favorite: http://mtvernon.wsu.edu/frt_hort/grape_pruning_basics.htm Note that it applies specifically to vinifera (typically european wine grapes) which are trained upwards from the support wire. Many of the American or hybrid grapes are trained to a higher wire and grow downwards. Ralph
