1. Buy sweet potato seedlings with intact roots.

2. Choose a piece of land in the yard. Sweet potatoes mainly grow underground, and the ground doesn't need much space. However, they like a warm environment, so try to choose a place with plenty of sunshine (especially living in the north) and good drainage.

3. Sweet potato is a tuber plant, which grows in soil. In order to make them grow well, it is necessary to deeply cultivate the soil for about 30 cm, loosen the soil and add gardening soil if necessary.

4. Treat the soil. Fertile soil is very important for a good harvest. Cover the surface with a layer of nutrient soil and pick up the big stones. Measure the Ph value of the soil. Acidity or alkalinity is adjusted to neutral pH by adding peat soil or plant ash. This is called soil improvement.

5. Determine the planting time. Because sweet potatoes like heat, they need warm soil to thrive. So we can't sow until spring at the earliest, that is, one month after the last frost.

6. Dig a hole. Sweet potatoes need more space than other gardening vegetables. Each hole is 30-60 cm apart. The depth from the base of the plant to the root of the tuber is 3 cm.

7. Planting. Put the sweet potato seedlings one by one in the pre-dug pit, and cover the stems with about 1.5 cm of soil. Sweet potato leaves will grow vines, while roots will grow tubers in the soil 15-30 cm deep.

8. Cover the film. In cold weather, protect your sweet potatoes with a film. This will also help to prevent the growth of weeds and the overgrowth of sweet potato vines and plunder the nutrients of tubers.

9. water When sweet potatoes are first planted, they need a lot of water. As time goes by, you should water them less until you only water them once a week. Start watering every day, and then reduce the number of watering weeks.

10. Wait for the tuber to grow. Sweet potatoes need a relatively long growth period, and they can't be harvested until early autumn (which coincides with Thanksgiving Day). Continue watering and weeding every week to make plants grow healthily.

1 1. Harvest sweet potatoes. The sweet potato should be fully mature about 120 days after planting. If possible, delay the harvest time of sweet potato (before frost) as much as possible, because it will grow bigger and more delicious tubers. /09fa5 13d269759ee3d3d745fa0fb43 166d22df30? x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_ 1%2Fquality%2Cq_85%2Fformat%2Cf_auto
