It is best to plant iceberg from July to September.

Icy vegetables are mostly planted in summer and autumn. Generally, they can be sown and cultivated from July to September. They mostly adopt soil cultivation or hydroponic cultivation. The seeds need to be soaked in warm water of 20-30℃ for 2-4 days. Sowing can be done after 2 hours, about 20-40 days after sowing, and planting can be started when the seedlings grow to 4-5 leaves.

Planting method

1. Soil selection

When planting ice vegetables, the soil needs to be loose and breathable, with sufficient fertility and good drainage. Ice vegetables are not tolerant to waterlogging and should not be planted in areas with heavy rainfall or low-lying areas. Otherwise, ice vegetables are prone to diseases. Growers can use a mixture of sandy loam soil and peat soil for planting.

2. Sow on demand

Soak the seeds in warm water at about 30℃ for about 2-4 hours before sowing, and then sow about 2-3 seeds in each hole. If you use seedlings When sowing seeds in a tray, you can sow about 2-3 seeds according to the 9 cm increments.

3. Seedling cultivation

After sowing, you can cover it with a layer of fine soil, about 3-5 mm. It should not be covered too deeply, otherwise it will affect the germination rate of iceberg. The temperature after sowing should not be too high or too low, and should be controlled at around 20°C. If the temperature drops, appropriate insulation should be used. When the temperature is high, air circulation should be strengthened to allow the temperature to decrease.

4. Planting

Under normal circumstances, transplanting can be carried out about 20-40 days after sowing, or when the seedlings grow 4-5 leaves.
