Purple sweet potato planting technology and management

Purple sweet potatoes are suitable for planting in spring, from February to March every year, because the temperature and climate in spring are conducive to the growth of purple sweet potatoes. However, if planted in the southern region, purple sweet potatoes can be planted around the Qingming Festival.

When planting, you should choose purple sweet potato varieties that are free of pests and diseases, of excellent quality, and healthy and plump, such as Zhejiang Purple Sweet Potato No. 1, Violet, Xu Purple Sweet Potato No. 1, etc.

2. Planting

You can choose the horizontal planting method for planting, which is conducive to the growth of purple sweet potatoes and also helps to increase the yield of purple sweet potatoes. If the soil is dry, you should water it before planting.

Purple sweet potato management method

1. Fertilization

When purple sweet potatoes are growing, they are in the root swelling period and require a large amount of potassium fertilizer. By early October, the temperature drops and the root's ability to absorb nutrients will gradually weaken, so more potassium fertilizer and phosphorus fertilizer should be used.

2. Cultivation

After transplanting the purple sweet potatoes, they should be tilled every half a month. The second time of tilling should be shallower to avoid accidentally damaging the roots of the purple sweet potatoes.
