It is important to maintain the temperature, and depending on the genus of sweet potato, the germination time varies from the time the seeds are sown to the time of germination. Care for young plants depends on the temperature and humidity of the seedlings. This is done by keeping the seedlings at a slightly lower temperature during the growing season to maintain the required moisture content, so that good young plants with broad leaves can be obtained. After transplanting, the seedlings should be uprooted. The optimum temperature for transplanting varies depending on the plant’s growth and planting system.
