Store them with sand. After sand storage, they can be sown in autumn or spring. Before planting, prepare the ground and apply enough base fertilizer. It can also be planted in indoor seedbeds. When sowing, place the umbilicus on the side to avoid bending of the radicle and young stem, which may affect the growth of seedlings in the future.
3. Watering and fertilizing
Before planting in the ground, the tree hole should be mixed with herb ash and organic fertilizer, and watered once after planting. Keep the soil moist before the new technology is released, and don't water it. Generally, nitrogen fertilizer is applied once in spring, and phosphorus and potassium fertilizers are applied once in summer to make the flowers flourish.
