1. Do flowers grow in the soil or on the ground

The root of peanut grows in the soil, but its flowers, leaves and stems grow on the ground. But after it blooms, a fruit needle will grow in the corolla, which is composed of ovary and ovary stalk. The fruit needle is oriented to the ground. After five or six days of extension, it will drill into the soil, and the ovary will fall into the soil, and then develop and expand into fruit under appropriate conditions. So its roots and fruits grow in the soil, but the flowers, leaves and stems will be on the ground. This is actually the origin of "luohuasheng"

2. Why do peanut fruits grow in the soil

After pollination, the flower of peanut will form an ovary handle at the base of its ovary within the next four or five days. After the ovary handle elongates, it looks like a needle, so it is called fruit needle. Because the ovary can only develop and expand into fruit in a dark environment, the fruit needle will drill into the soil. The soil environment is dark and the water and nutrients are sufficient, so the ovary can expand rapidly and gradually develop into fruit. Only the growth conditions in the soil can promote the development of ovary, so the fruit of peanut will grow in the soil

3. A simple way to grow peanuts

Seed selection: select high-quality and full peanut seeds first. For potted peanuts, it is generally good to choose three or four because of limited space. After selecting the seeds, soak them in warm water for one night to promote germination

Sowing: prepare a flowerpot of appropriate size, fill it with loose and breathable soil, and spray some water to wet the soil. Then bury the sprouted seeds in the soil, about two or three centimeters deep. Then cover it with a thin layer of soil and spray some water appropriately. The flowerpot can also be covered with plastic film, which can have a certain effect of heat preservation and moisture retention

Management: move the flowerpot wrapped with film to a place with moderate and sufficient light to avoid exposure. In this way, you can see the germination of seeds after waiting for about one. At this time, you can tear off the plastic film and water it on time every day
