Overview

Florida gardeners can enjoy several types of muscadine grapes, a heat- and humidity-tolerant grape native to the southeastern United States. North and central Florida provide a better atmosphere for grapes than south Florida. Grapevines require extensive pruning to manage the size of the fruit crop and keep the vines healthy. Unpruned vines bear too much fruit and can tear down the trellis system. They also contract disease since they lack air circulation and light.

Step 1

Wait until the grapevine is dormant to prune. The University of Florida advises pruning grapevines from mid-January to mid-March, since pruning in early winter can cause winter damage if the vine isn't fully dormant.

Step 2

Examine 1-year-old wood (last season's new growth) to identify the healthiest, strongest looking canes. The number of canes you want to keep depends on your trellising system: a four-arm trellis system needs four canes and a two-arm system needs two canes. Chose the canes to keep.

Step 3

Leave the canes you've selected. Then choose four shoots to be renewal canes and trim these back, leaving only two buds. Much of your new growth will emerge from these shoots.

Step 4

Remove the rest of the 1-year-old wood, since you don't want it to produce grapes. Expect to remove at least 80 percent of 1-year-old growth, advises Ohio State University.

Step 5

Cut back any growth from the central shoot that climbs above your trellising system. You want to train the vine to grow up, not out.

Step 6

Clip off suckers that grow along the central vine or from the root stock. This poor-growth wood will not bear fruit and saps energy from the vine.
