Treatment of seeds

The seed surface is covered with a layer of wax, which will seriously affect the germination of the seed if it is not cleaned. Before sowing, you can soak it in warm water for a period of time, or rub it with alkali for a while, and then rinse it with water. Both methods are relatively simple and can effectively remove wax

Seed germination

For sowing in early spring, first water the soil evenly, and then spread the seeds evenly on the sandy soil, covered with a thin layer of soil. At this time, maintain a certain moisture and temperature, and wrap them with plastic film, which can not only keep warm, but also moisturize. Open the film during the day for air permeability and watering, which is conducive to seed germination

Treatment of seedlings

When the seedlings grow to 5 cm to 8 cm high, the seedlings with weak rise can be removed, and the spacing of seedlings can be increased. When the seedlings grow to about 20 cm, the seedlings with weak growth can be selected for removal. Transplantation or colonization can also be carried out at this time, but it is best to carry out it between April and may

Seedling maintenance

Watering can be carried out once in about 10 days, and fertilization and weeding should also be carried out during the second seedling selection. Do not be short of water during the growth period. If you find that the soil surface is in a dry state, you should water it immediately. It is a plant that likes water and fertilizer, especially during the growth period. However, it is not allowed to keep the soil moist or ponding for a long time
