Even after following the book rules still, some additional tactics might increase the yield and efficiency in the process of cultivation. Starting from soil preparation, right plantation, nurturing, irrigation, disease and pest control are the general factors which are to be ensured.

Right Place Right growth:
A large, open, sunny space with good soil. 50 to 100 square feet per vine is required if growing vertically on a trellis or arbour. About 8 feet between rows is optimum if planted horizontally in rows.
Sunny Day is a Happy Day:
Grape plants need 6 to 8 hours of exposure to direct sun for their well-being and better growth.
Selection of the Right Variety:
There are mainly three varieties of grapes excluding the Hybrid ones.
American (Vitis labrusca) grapes are the most cold-hardy (zones 4-7) and thrive in short-season growing areas such as the Northeast. These are mainly used for table grapes, juices, and jellies.
European (Vitis vinifera) grapes prefer a warm and dry Mediterranean-type climate (zones 7-10) with a longer growing season. Depending on the variety, these are used for winemaking and as table grapes.
Muscadine (Vitis rotundifolia) grapes are native to North America and grow well in the humid South (zones 7-9). These are most often used for winemaking as well as table grapes.
It would be wise to choose according to the climate of the probable region.
Feed With Optimum Fertilizer:
Neither high nor low, grapes don’t require much fertilizer. An optimum level in early spring would work great. About 8 to 10 ounces of 10-10-10 or 10-20-20 fertilizer can be used. Besides a layer of high-quality compost can be added to the base of your grapes to provide an adequate amount of nutrients.
