Learn the method and grow common things into potted plants even more beautiful than pothos and spider plants

Autumn has arrived, and many flower-loving friends grow some flowers at home. Flowers come in all kinds, so everyone has their own favorites, but sometimes buying flowers costs quite a bit of money. But actually, some things in everyday life can be grown into very beautiful potted plants without spending money, prettier than many flowers. So, what things can be made into potted plants that are even prettier than flowers?
Celery
If the celery you bought still has roots, you can cut it off about 6cm above the roots, then put it in clean water. You can use toothpicks to hold it in place, then change the water about every 2 days. Basically, in about 7 days new tender shoots will grow, and before long it will be lush and green. When you want to eat it, just cut some off, and soon new tender shoots will grow again.
Sweet potato
First find a container, then put the sweet potato in, with the water level at one third of the sweet potato. Then change the water often to keep the water clean. Basically, in about a week green leaves will grow. When the leaves grow more and more vigorously and the roots grow more and more vigorous, you can transplant it into soil. If you want to eat sweet potato leaves, you will soon be able to!
Chestnut
First soak raw chestnuts in clean water, with the pointed end facing down, and the water level at about one half of the chestnut. Then change the water every day to keep the water clean. Basically, in about 7 days little white tender sprouts will grow, and then you can pot them. Water the prepared soil thoroughly, then put the chestnuts in, burying them a bit shallowly, then water about every 3 days to keep the soil slightly moist. Soon tender sprouts will grow, then put them in a sunny spot, and in about a month you will have a lush little potted plant.
