Grapevine Post-Harvest Nutrition Crucial to Next Year’s Crop

Heavy rains and cloudy days early in the growing season may have delayed maturation of grape crops in some areas of the Midwest, but hot conditions in August triggered heavy crops in time for a somewhat delayed harvest. Stressed grapevines will need a nutritional recharge before the leaves yield to the change of seasons.“It’s always nice to finish the harvest, but the work is not yet done. … [Read more...]

Heavy Early-Season Rains Create Potassium Deficiency

Potassium is important for grapevines to function and is one of the most frequent nutritional deficiencies of vines. A grapevine with inadequate potassium produces poor, unevenly ripened fruit and reduced yields. Severe deficiency results in defoliation. Leaves in the mid- to basal portions of shoots are affected. Clusters of deficient vines tend to be small with a few unevenly ripened berries. … [Read more...]
