• A standard 10-10-10 fertilizer can also be used, especially in the grape vine's first three years following planting. Sprinkle about 1/4 lb. of 10-10-10 in a circle about 1 1/2 feet away from the main stem after planting. In the second year, increase rate to 1 lb. and in the third year increase again to 1.5 lb.

When to Fertilize Grape Vines

• Most growers fertilize their vines in the fall following the grape harvest. Grape vines can also be fertilized in the spring prior to bud break. Applications of fertilizer during the growing season are not recommended because it will cause the grape vines to grow vigorously. That in turn can produce inferior fruit and set the vines up for failure during the harsh winter months ahead.
