    Start with a soil test through Cooperative Extension. Here's the info: http://soilslab.ifas.ufl.edu/ESTL%20Tests.asp According to the trusty Clemson U. Cooperative extention folks, "Grapes prefer a soil pH of 5.8 to 6.5. After the vines are planted, but before new growth starts, add one-quarter cup of 10-10-10 fertilizer around each plant. Keep the fertilizer at least 6 inches from the vine. Repeat at six-week intervals until mid-July. On 2-year-old vines, double the first year rate and use the same intervals. Bearing vines will need 2½ pounds of 10-10-10 per plant applied in March. If growth is poor on producing vines, apply 1 pounds of 10-10-10 per plant in May. Foliar magnesium deficiency may become noticeable in midsummer. This deficiency is characterized by a yellowing between the leaf veins on the older grape leaves. If the soil pH is sufficiently low to warrant liming, use dolomitic lime to help prevent magnesium deficiency in future years. Otherwise, magnesium sulfate (Epsom salts) should be applied and watered in. For young plants, apply 2 ounces around each vine, keeping the salts away from the trunk 6 or more inches. Apply 4 to 8 ounces per mature bearing vine. It may require two to three years of magnesium application to bring the level up for the best plant performance."
