Is it better to grow onions in water or soil?

It is recommended to grow onions in soil because the nutrients in sandy soil are richer and more suitable for the growth of onions. Moreover, onions are prone to root rot if soaked in water, which is not as convenient and simple as growing them in soil.

Hydroponic onion methods and precautions

1. Plant treatment: First, rinse the onion skin, peel off the dry outer skin, cut off a piece of the root, prepare a low container, place the onion in the hydroponic container, add a small amount of clean water, and the water should not cover the onion.

2. Plant maintenance : Place the container of hydroponic onions in a bright place without direct sunlight. In the early stage, change the water once a day to ensure the cleanliness of the water. Clean the part of the onion in the water every time you change the water.

Methods and precautions for soil-grown onions

1. Soil selection : The soil for growing onions should be loose and fertile. You can also mix sandy soil and humus in a certain proportion, or directly purchase professional breeding soil.

2. Planting : When planting onions, cut off the onion heads and bury them about 1 cm below the soil. Water them every 3 days to keep the soil moist. The onion shoots will slowly grow out, but do not water them too much to prevent root rot.
