1. Orchard cleaning: in the techniques for growing Kyoho grapes in the south, before the vines are taken out of the soil, thoroughly clean up the dried fallen leaves, weeds, grape stems and so on in the vineyard, peel off the old cracked bark on the trunk and canes, and burn or bury them deep in a centralized manner.

2. Take out of the soil at the right time and delay trellising: in the techniques for growing Kyoho grapes in the south, it is generally suitable to take the vines out of the soil when the average daily temperature reaches 10°C. After taking them out, first keep the canes in a cold-protection state, and after the lower buds sprout and swell, tie them up onto the trellis and let the canes grow at a slant.

3. Spray a fungicidal eradicant: when the buds swell into a fuzzy ball shape, spray 5 degrees Baume lime sulfur mixture or 200-times liquid sodium pentachlorophenate, covering both the upper and lower parts of the canes and the ground.

4. Apply water and fertilizer as appropriate: in the techniques for growing Kyoho grapes in the south, areas with the conditions should apply sufficient organic fertilizer after harvest in autumn. When planting, choosing excellent southern grape varieties is also key. Before the grapes bloom in spring, if the orchard is not excessively dry, try not to apply additional fertilizer or water, and especially do not apply nitrogen fertilizer, so as to avoid excessive early growth, which is unfavorable for fruit set. After the flowers fall, when the berries grow to the size of soybean grains, apply fertilizer and water heavily once, and afterward water frequently with small amounts according to drought conditions.

5. Timely bud removal, shoot selection and pinching: the early growth of grapes mainly depends on the stored nutrients from the previous year, so sprouting buds should be selected and retained in time, keeping the flat and plump buds and removing the others. From 3-5 days before flowering, pinch the shoots above the cluster leaving 4-6 leaves, keep one secondary shoot at the top, and repeatedly pinch the secondary shoot leaving two leaves each time until a total of 17 leaves is retained. When trimming the cluster, first remove the secondary clusters and weak small clusters, then pinch off 1/5-1/4 of the tip of the cluster. For clusters with berries that are too dense, remove the small berries; each cluster must not have more than 60 berries at most.

6. Pest and disease control: in the techniques for growing Kyoho grapes in the south, the main diseases are downy mildew, white rot and anthracnose. Use 75% chlorothalonil 600-times liquid to control anthracnose, 50% carbendazim 800-times liquid to control white rot and anthracnose, and 64% sandoz 500-750-times liquid to control downy mildew. The main pest is the leafhopper, which can be controlled with 50% dichlorvos 1000-times liquid.
