What are the key points for growing choy sum? The latest essentials in one article

1. Choosing varieties

There are many varieties of choy sum, and you can easily buy several kinds at the market. If you want to grow it, you should first consider factors such as the local climate and soil. In addition, you should also consider the characteristics of the variety, which one is easier to grow and has higher yield, and choose a variety suitable for local planting based on all aspects.

2. Planting time

Although choy sum can be planted all year round, the climate and environment differ from place to place, so the planting time also varies. If you choose to plant an unsuitable vegetable in an unsuitable season, it will also make survival difficult and growth poor. Therefore, planting time is extremely important. Generally, it is planted around March in spring or from August to September in autumn. This period is the common time for planting choy sum and also the period when choy sum grows best, with a clear increase in yield.

3. Reasonable close planting

Generally, when the seedlings grow 4-5 true leaves, they should be transplanted in time. The transplanting density should be determined according to the variety's form, planting time and planting purpose. Generally, early-maturing varieties planted in summer are mainly grown for harvesting the flowering stalks, have a short growth cycle and grow quickly, so a plant and row spacing of 13 cm × 16 cm is suitable. For mid- and late-maturing varieties planted in summer and autumn, the growth cycle is long and the plants are large, so they are not suitable for planting too densely; a plant and row spacing of 16 cm × 20 cm is better.

4. Harvesting at the right time

Harvesting choy sum must also be controlled strictly. Generally, the suitable harvest time is when the flowering stalk is level with the tips of the upper leaves and the flower buds are just beginning to open. To harvest side shoots, you can cut the main flower at the 2nd-3rd node from the base; for a one-time harvest, cut 1-2 nodes lower. If harvested too early, the flowering stalk has not yet matured and grown, and the yield is lower; if harvested too late, the flowering stalk becomes old, the taste is poorer, and the quality and marketability are affected.
