260 Apply fertilizer in February, except on sandy soils, apply in split applications, one-half in February and one-half when cane growth is about 6 inches long. The nitrogen rate should be 40 and 80 lbs nitrogen per acre. Use lower rate for older vines or when pruning weight is greater than 2 pounds per plant. Use higher rate for younger vines, when pruning weight is less than 2 lbs.

To convert acre recommendations to per plant rate, divide by 544 for bunch grapes and 270 for Muscadine grapes.

261 This is a boron sensitive crop. Apply 0.6 lbs boron per acre or apply Solubor in two cover sprays at the rate of 1 lb Solubor per 10 gallons of water. (When soil test boron is not excessive)

653 Soil test zinc is low, however, this is not a zinc sensitive crop, therefore no zinc is recommended. (When soil test zinc is low)
