1、 Sufficient light

Sunlight is an important factor in growth. The synthesis of nutrients is inseparable from the exposure of sunlight. It needs to be exposed to sufficient sunlight to grow normally. It can be placed on the balcony. In this way, there is enough sunlight to ensure that the green onion can grow strong. If you have been in a dark environment, it is difficult for onions to synthesize nutrients. Naturally, they will grow longer and thinner

2、 Proper spacing

Because it is potted planting, it cannot be planted too densely, otherwise nutrients can be supplied, and the spacing needs to be ensured

3、 Sufficient water and fertilizer

If you want it to grow strong, the supplement of water and fertilizer is also very important. It is a drought resistant plant, but it does not need any water. When it grows vigorously, you must not apply too much water, otherwise it will damage the root and only make it grow thinner and thinner. Pay attention to the application of fertilizer. The rotten organic fertilizer is the most appropriate, so as to ensure that the shallots grow thicker and thicker

4、 Picking method

Its growth rate is very fast. When it is buried, it will expose seedlings. If you want it to be stronger, you can't harvest it immediately, but wait for its nutrients to accumulate for a period of time. We should also pay attention to picking in a scattered way instead of concentrating on one tree
