How to prune solaris grape

Late winter for main structural pruning; summer for shoot-tip pinching after fruit set. Winter: cut all lateral shoots back to 2-bud spurs along a permanent cordon, removing 80–90% of previous year's wood. Summer: once the vine reaches the top wire, pinch shoot tips 2 leaves above the highest bunch to redirect energy into ripening rather than vegetative growth.

Annually in late winter; summer pinching as needed. Solaris Grape needs regular annual pruning — it is a disease-resistant German hybrid wine variety that grows vigorously. Prune in late winter using spur pruning on a permanent cordon (cut laterals to 2-bud spurs) or cane replacement. Solaris can set heavy crops, so summer pinching of shoot tips after 2 leaves above the top wire helps balance the vine.
