When should sweet potatoes be planted and seedlings started?

Sweet potato, also known as sweet potato , is popular in many regions and is regarded not only as a delicacy because of its deliciousness, but also as an important crop because of its economic value. Sweet potato cultivation is very common in China, from north to south. To successfully grow sweet potatoes, you first need to get healthy sweet potato seedlings before you can transplant them. So when should sweet potatoes be planted and seedlings started?

When should sweet potatoes be planted and seedlings started?

The best time to grow sweet potato seedlings depends on the climatic conditions in your area. Normally, cultivation begins in the spring, around March, around the Jingzhe solar term. For southern regions with warmer climates, the cultivation process can be started in February. In the northern regions with colder climates, seedling cultivation needs to be completed before the Qingming Festival.

Since the temperature is relatively low during the cultivation period, sweet potato seedlings are usually cultivated in a hotbed and appropriate insulation measures are taken during this period. In addition, in order to ensure that the timing of planting and sales is proper, the start time of cultivation needs to be accurately controlled. Generally speaking, cultivation work should be started 4 to 5 weeks before transplanting the sweet potato seedlings.

How to cultivate sweet potato roots

After harvesting sweet potatoes in autumn, select healthy sweet potato roots that are thick and undamaged as seed roots, retaining about 3 segments for each root. After removing the leaves, adjust the size of the cultivation room according to the expected number of cultivation. If cultivation is carried out in a greenhouse, the plant spacing should be planned reasonably and the cultivation pits should be prepared.

After planting the sweet potato roots, set the guy wires according to the predetermined plant spacing and fix the sweet potato roots and the guy wires together. When the sweet potato roots begin to sprout, pick about 3 new sprouts from each root and tie a rope to each new sprout so that the subsequent sweet potato vines can climb and grow smoothly along the rope.

Sweet potato seedling cultivation precautions

Due to differences in environmental conditions in different places, such as climate and temperature, the cultivation time of sweet potato seedlings will vary. There are many different cultivation techniques, so when cultivating, growers need to combine their own cultivation skills and the specific conditions of their area to carefully choose the cultivation method that best suits them.

The sweet potato root cultivation method can maximize the use of planting space, especially in large-scale cultivation, which can significantly increase the output of sweet potatoes. Each cultivation technique has its own unique advantages and limitations. Regardless of the cultivation method used, the temperature must be properly adjusted during the cultivation process to ensure the healthy growth of sweet potatoes.

The above is an introduction to the seedling cultivation time of sweet potatoes. In the process of cultivating sweet potato seedlings, everyone should pay attention to the local environmental conditions and temperature.
