Every day, I always struggle about what vegetables to eat and what vitamins to add. The sweet potato leaves and sweet potato leaves I saw when I was a child and gave them to pigs, or directly thrown away, turned out to be really delicious and nutritious. They are still delicious to eat. They taste softer than spinach and more delicious than Chinese cabbage. Do you know their nutritional value? The test shows that each hundred grams of fresh sweet potato leaves contains 2.28 grams of protein, 0.2 grams of fat, 4. 1 gram of sugar, 0/6 mg of mineral potassium/kloc-0, 2.3 mg of iron, 34 mg of phosphorus, 6.42 mg of carotene and C0.32 mg of vitamin C. Compared with common vegetables, the contents of minerals and vitamins are superior, and the content of carotene is even higher than that of carrots. Therefore, the Asian Vegetable Research Center has listed sweet potato leaves as a highly nutritious vegetable variety, calling them "vegetable queens". Now introduce how to grow sweet potatoes in flowerpots on the balcony.

Cut a piece of vine about 10 cm directly from the sweet potato vine, and the slightly older vine will have higher vitality.

Choose flowerpots with a diameter greater than 10 cm, because they grow very fast in the later stage and need enough nutrition. Use ordinary garden soil, or humus soil, and add some sand to increase air permeability.

Cut the cut branches well, water them enough, and put them in a cool and shady place for about three days. Generally, they begin to grow roots in a week.

Apply more organic fertilizer during the growth period, water more in summer, and control water appropriately in early autumn.
