When is the best time to plant sweet potatoes?

Sweet potato, also known as sweet potato, is resistant to high temperatures and prefers cool climates. It is an annual herb with a very wide planting area.

The stems, leaves and underground rhizomes of sweet potatoes are all edible. If you only want to eat the stems and leaves, you can plant them in spring, summer and early autumn .

However, the usual planting time for sweet potatoes is between April and May, and the best time is mid-May .

At this time, the soil moisture and external temperature are relatively stable, and the seeds are easy to germinate and take root. The planting time of sweet potatoes must be based on the weather and temperature, not too early or too late, otherwise it will affect the harvest .

As long as the root system and soil have high moisture, the sweet potato seedlings will generally grow within 3 to 7 days, and the survival rate is high. Only a few seedlings die without the need to replant, and it will not affect the yield .

After a month, the sweet potato vines will grow to about 2 meters long . It is also the time to plant wheat stubble sweet potatoes. You can choose those with thicker stems for cuttings, which are called wheat stubble sweet potatoes.

The temperature and light intensity are high during the season of wheat stubble cuttings, so it is best to choose to do it on a semi-cloudy day or before the rain . This time can promote rooting and seedling growth and increase the survival rate. On days with high light intensity, cuttings should be done early or late, and the root water should be appropriately increased.

Sweet potato seedlings grow very fast in July and August. When there is abundant rainfall, many adventitious roots will grow at the nodes where the stems contact the soil .

These adventitious roots not only do not produce fruit but also absorb a large amount of nutrients from the soil, thus affecting the growth of the underground rhizomes of the main root system.

Therefore, after adventitious roots take root, it is necessary to promptly lift, turn, and shorten the vines to prevent nutrient loss from affecting the growth of the underground rhizome of the main root.

The cut sweet potato vines are very good vegetables. The fresh top leaves are edible. They can be used to make cold dishes in the summer to stimulate appetite and improve immunity. They are both nutritious and safe.

Sweet potato seedlings are the leafy vegetables with the highest survival rate of cuttings. In spring and summer, you can not only eat the leaves but also harvest sweet potatoes. If you only want to eat the stems and leaves, you can also plant them at home. In winter, the room temperature is not lower than 25 degrees, and they can still grow. You can continue to harvest fresh stems and leaves for consumption.
