1. Seed selection. First, choose healthy sweet potato tubers without any damage as seed potatoes. The seed potatoes need to be disinfected before sowing. Generally, you can sow them in spring.

2. Soil. Deeply plow the soil, dry it, and sterilize the soil. Then place the seed potatoes in the soil, cover the soil, water, and wait for seedlings to emerge.

3. Cuttings. When the seedlings grow to a certain height, cuttings need to be carried out, usually before May, so that they can be put on the market in advance. Do not cut too densely when cutting, and need to plant reasonably densely to avoid affecting ventilation. Cuttings need to be carried out on a cloudy and rainy day, and watering can be done after planting. After planting, it is necessary to weed and loosen the soil twice, and topdress in time to meet the future growth of sweet potato leaves.

4. Fertilize. After each picking, you need to topdress with thin farmyard manure or compound fertilizer, or you can topdress with vegetable-specific foliar fertilizer; remember to water once after fertilizing to promote nutrient absorption.

5. Picking. Sweet potatoes can be picked when their vine tips grow to about 20 centimeters, usually every 10 days or so. Measures should be taken to preserve freshness after picking.

6. Prevention and control of pests and diseases. There are relatively few diseases and insect pests on sweet potato leaves, and management is simple. Generally, if you maintain the sweet potato leaves well and do a good job in field management, diseases and insect pests are rare. Once pests and diseases are discovered, they must be promptly controlled.
