A Detailed Guide to Wild Grape Cultivation Methods: Easily Master the Key Growing Points

Growing wild grapes requires cutting propagation or graft propagation, followed by arranging the planting density. Winter and summer pruning of wild grapes is mainly determined by the branches and buds, and providing pollinator trees can improve the fruit-setting rate. Wild grapes have poor resistance to downy mildew, so prevention should be the priority in management.

Wild Grape Cultivation Methods

I. Seedling Raising

1. Cutting propagation: Wild grape cuttings are very difficult to root and survive, but soaking the cuttings in 100ppm-200ppm sodium naphthalene acetate and keeping them at 25-30°C for 24 hours can achieve a rooting rate of 85%-90%, which is 20-40 times higher than without chemical treatment. When treating this way, the temperature must not be too high or too low, otherwise rooting is difficult or the cuttings die.

2. Graft propagation: Collect wild grape seeds, sow them and let them sprout, then graft hermaphroditic wild grape varieties onto them; Beta rootstock can also be used to graft excellent wild grape varieties.

II. Improving the Fruit-setting Rate

The main ways to increase the fruit-setting rate: provide pollinator trees, with a planting ratio of complete-flower wild grapes to male plants of 5:1 or 3:1, giving good natural pollination results. Spraying a 0.3% boric acid aqueous solution at the flowering stage can increase the fruit-setting rate by 66.7%.

III. Pest and Disease Control

Before the rainy season arrives in late June, Bordeaux mixture can be sprayed for control, then sprayed once every 7∽10 days at a concentration of the equal-amount formula diluted 180∽200 times. If disease occurs, a 300-times aqueous solution of 40% fosetyl-aluminium wettable powder can be sprayed, which has a very good therapeutic effect.
