Suitable planting time of lettuce balls
The suitable sowing date of lettuce is around April in spring, when the temperature and humidity are more suitable for its seed germination, and it can also be carried out in autumn, when the climate is cool and suitable for lettuce growth. Greenhouse cultivation can be carried out all year round.
Planting methods and key points of lettuce balls
1. Sowing: The seeds of lettuce balls are relatively small and light, which need to be mixed with fine sand, then spread on the soil and covered with a thin layer of soil. It is best to accelerate germination before sowing, so that germination will be faster.
2. Transplanting: When the lettuce balls grow to 5-6 real leaves, transplant them and move them into a big pot together with the old soil. It will be successful in a week or so, and then provide brighter sunshine.
Matters needing attention in daily management of lettuce balls
1, temperature: lettuce balls like a cool environment, and the optimum temperature is about 15 to 20 degrees Celsius. When the temperature is high, it should be cooled quickly to avoid sunburn. If the temperature is low, measures should be taken to keep warm.
2. Fertilizer: lettuce balls have a great demand for fertilizer, so some organic fertilizer should be applied to meet their growth needs. When applying fertilizer, the fertilizer can be dissolved in water and poured into the soil, which can promote its absorption of nutrients.
3. Illumination: When breeding, lettuce balls should be placed in a sunny place, but the illumination should not be too strong, otherwise the leaves will turn yellow. But don't see the sun for a long time, otherwise the growth will be poor and the output will drop.
