How do you grow a sprouted onion into a bonsai?

1. Hydroponics

1. Prepare a hydroponic container: Once an onion has sprouted, it can be made into a hydroponic bonsai; it is easy to set up and care for, and it also has some ornamental value. You can choose a container with a mouth smaller than the onion, so that it can hold the onion up and the roots can sit right in the water.

2. Choose an onion: From the sprouted onions, pick one with a good shape and no damage.

3. Prepare the onion: Peel off the old outer skin of the onion and shake off the soil from the roots at the bottom. Prepare clean water, put the onion roots into the clean water and wash them clean, exposing the white root system.

4. Start hydroponics: Fill the container with clean water and set the onion on the mouth of the bottle; do not let the onion bulb soak in the water, only let the roots touch the water. To promote growth, you can add aspirin tablets to the water.

2. Soil cultivation

1. Prepare the pot and soil: A sprouted onion can also be planted in soil. First choose a flower pot and fill it with loose, breathable, nutrient-rich soil.

2. Prepare and take out the sprout: Peel off the outer skin of the onion without damaging the roots below, cut the onion in half, and take out the intact young sprout inside.

3. Plant it: Loosen the soil, plant the onion sprout in it, and cover it with soil. Do not plant it too deep; the top of the onion should be left exposed above the soil surface.

4. Later care: After planting, water it thoroughly and keep it in a place with plenty of light.
