How do you prune out of control grapes?

Cut back the newest fruiting canes you marked with pruning or lopping shears, leaving about 15 buds on each. Cut the canes to just above a healthy bud at a 45-degree upward angle. Pinch off all unproductive shoots and those with fewer than 14 well-exposed leaves, spacing them as evenly as possible during removal.

Should grapes be thinned?

Thinning helps keep fruit from rubbing and gives it room to develop and ripen properly. Good thinning practices also create tight clusters of grapes which travel and keep better than loose, thin clusters. Grapes typically set more clusters than they will have the energy to develop.

One-year-old wood (the previous summer's growth) should be pruned back to three to five nodes per spur. The spurs should be evenly spaced along the cordon.

How do you increase the size of grapes?

Give grapes a chance to grow larger and to get more plant nutrients and water per grape by shortening the cluster. Take off the bottom half of the cluster, leaving four to five side branches near the top. Since these branches grow sideways from the cluster's main stem, they have room to hold fruit without crowding.

Why are my grapes so small?

There are several reasons for grapevines producing small grapes. In order, they include young plants unable to maintain growth and produce fruits simultaneously, not enough water during fruit maturation, over-fertilization, cool summer temperatures, or a short growing season.
