Sweet potatoes can be planted several times a year and usually take several months to harvest.

How many seasons of sweet potato are planted in a year

Sweet potatoes can be planted once a year . The best time to plant sweet potatoes is from January to March every spring, because sweet potatoes are suitable for growing in high temperature and high humidity environments and are not resistant to severe cold. Sweet potatoes will only sprout and grow leaves when the average temperature is 20-25 degrees.

Sweet potato planting conditions

1. Temperature

High temperature and high humidity are beneficial to the growth of sweet potatoes, but high temperature and dryness will cause the leaves to die. The minimum temperature for sweet potato germination is 10°C. The temperature during the growth period of sweet potatoes needs to be 20-25°C, but not more than 35°C, otherwise it will cause death.

2. Lighting

Sweet potatoes are not very demanding on light. They are relatively shade-tolerant and can grow normally under dim light, but they need long periods of sunlight, which is beneficial to the growth of sweet potatoes and improves production and quality.

Sweet potato harvest time

The harvest time of sweet potatoes is usually between August and October. Early-maturing sweet potatoes can be harvested in August, while late-maturing sweet potatoes can only be harvested between September and October. It takes about 180-260 days from planting to harvesting.

Sweet potatoes should be dug out in time after they are ripe, especially in the northern regions where the temperature drops in autumn and the sweet potatoes are easily frozen. In the southern regions where it is relatively warm, you can wait until February of the following year to dig them out.
