Pruning
Annual pruning is important in maintaining a uniform yearly production of quality fruit.
The best time to prune grapevines is in the dormant season after the danger of severe cold weather has past.
When ‘Lay-down’ management is used, prune mildly in fall and complete pruning at spring trellising.

Fertilizing
Grapes perform best where the soil pH is between and .
Apply 8 ounces of 10-10-10 fertilizer per plant seven days after planting .
Annually apply 11/2 pounds (10-10-10) per vine in the third and later years about 30 days before new growth begins in the spring.
36
Fertilizer Application
Do not concentrate fertilizer at the base of the trunk. Keep fertilizer 6 to 12 inches from the trunk and spread evenly under the spread of the vine.
37
Weed Management/Mulch
For best vine performance, avoid using thick organic mulches…heat needed for growth.
Use tillage, herbicides or black plastic mulch to control weeds.
38
Diseases
Common grape diseases are black rot, downy mildew, powdery mildew, phomopsis cane and leaf spot, and botrytis bunch rot or gray rot.
Proper spacing for air circulation.
Consider a disease pesticide program.
Use organic Bordeaux and horticultural oils.
