Seed treatmentThe surface of the seeds is covered with a layer of wax. If it is not handled cleanly, it will seriously affect the germination of the seeds. Before sowing, you can soak it in warm water for a while, or rub it with alkali for a while, and then rinse it with water. Both methods are relatively simple and can effectively remove the wax. Seed germinationSowing should be carried out in early spring. First, water the soil evenly, then spread the seeds evenly on the sandy soil and cover it with a thin layer of soil. At this time, maintain a certain humidity and temperature. You can wrap it with plastic film, which can keep warm and moisturize. During the day, lift the film for ventilation and watering, which is conducive to seed germination. Treatment of seedlingsWhen the seedlings grow to 5 cm to 8 cm in height, the weaker seedlings can be pulled out. At the same time, the distance between the seedlings can be increased. When the seedlings grow to about 20 cm, the weaker seedlings can be selected for removal. Transplanting or potting can also be done at this time, but it is best to do it between April and May. Seedling careWatering is only required once every 10 days, and fertilization and weeding should also be carried out when selecting seedlings for the second time. Water is essential during the growing period. If you find that the soil surface is dry, water it immediately. It is a plant that likes water and fertilizer, especially during the growing season. However, the soil should not be allowed to remain moist or waterlogged for a long time. |
