Pruning grape vines for dummies

Timing and Tools

In grapevine pruning, timing isn't just an art—it's also a science. We aim to prune in late winter or early spring, after the threat of hard frosts but before bud break.

Pruning grape vines during growing season

It's when the vine is dormant, but it's about to channel its stored energy into new growth. Pruning now means we can manage where that growth will happen without causing undue stress to the plant. As for tools, cleanliness and sharpness are essential—so use sterilized pruning shears and loppers.

This helps prevent the spread of diseases and ensures a clean, swift cut that the vine can heal more efficiently.

Identifying Old Canes and Weak Branches

Pruning isn't random—it's a targeted approach to help your grapevine be the best it can be.

Pruning grape vines in fall

First, look for the oldest canes on your grapevine; they're typically darker and thicker. These old canes may be less productive and can be trimmed back by about two-thirds for more effective growth. Also, look for weak or damaged branches—yellowish or discolored leaves often characterize them.
