How Deep Should Sweet Potatoes Be Planted? There Is More to Planting Depth Than Meets the Eye

When planting sweet potatoes, people sprout seedlings from sweet potato tubers and then transplant the seedlings into the soil, so how deep should sweet potatoes be planted?

1. How deep should sweet potatoes be planted?

The planting depth of sweet potatoes should be determined according to soil conditions. Generally, a planting depth of about 8 cm is suitable for drier soil, and a planting depth of 5-7 cm is suitable for moister land. When planting sweet potatoes, the double-row staggered-hole diagonal insertion method can be used, generally planting 3000-4000 plants per mu.

2. When is the best time to plant sweet potatoes?

Generally, sweet potato seedlings are planted on cloudy days, mainly because the seedlings have no root system when planted. If planting is done on a bright sunny day, before the sweet potato roots have grown, the sweet potato leaves will already have evaporated all their water under the sun's rays. However, planting should not be done while it is raining either. Although there is plenty of water during rain, which can ensure the survival rate of the sweet potato seedlings, planting sweet potato seedlings in heavy rain can easily cause woody roots to form, affecting the quality and yield of the sweet potatoes. Therefore, it is best to plant on a cloudy day or after rain.
