How many seasons can sweet potatoes be planted in a year?

Sweet potato, a legume, is rich in dietary fiber. It can be planted once a year in the northern region , and in the warm southern regions there is a two-year four-harvest system with spring potatoes and summer potatoes, which are planted in rotation with other crops. The spring and summer seasons of the year are more suitable for growing sweet potatoes, the specific time is mid-April to early May in spring, and mid-June in summer.

Sweet potato planting conditions

Sweet potatoes are suitable for growing in a warm, sunny environment. During maintenance, try to maintain the temperature at 22-30℃. Sweet potatoes kept in the shade for a long time are not conducive to the growth of the plant or the fruiting. Sufficient light needs to be provided during the growth process to promote photosynthesis and synthesize the nutrients needed for plant growth.

Sweet potatoes are highly adaptable and are drought-resistant but not cold-resistant. During maintenance, water them as much as possible in small amounts and multiple times to keep the soil slightly moist. Avoid flooding with large amounts of water to prevent water accumulation in the soil and inhibit root respiration. Sweet potatoes are best grown in loose, breathable, and well-drained sandy loam. When planting, you can sprinkle some organic fertilizer on the soil.

Sweet potato harvest time

Sweet potatoes grow quickly and can usually be harvested 160 to 200 days after sowing . Regardless of whether they are planted in spring or summer, they are generally mature and available in October each year.
