1. Not enough yearsReason: Amaryllis can be cultivated through two methods: seed propagation and division. Seed propagation usually takes 2 to 3 years before it blooms, so during this period it will only grow leaves. Solution: We can observe the ball at its root. If it is larger than 5 cm, it will bloom during its flowering period. 2. Insufficient nutrientsReason: When plants bloom, they need a lot of nutrients. If the nutrients are insufficient at this time, it is difficult for them to bloom, and they will only grow branches and leaves. Although their roots can store a lot of nutrients, it is far from enough for their use during the flowering period. Solution: Provide nutritional supplements before and during flowering. It is also recommended not to grow multiple plants in one pot, as this will greatly reduce the effect of fertilization. 3. Planting too deepReason: When planting Amaryllis, its roots are buried too deep in the soil, and there is almost no air in the soil. This will cause the roots to be unable to breathe freely, which will greatly reduce its growth rate; Solution: The normal planting method is to bury 2/3 of the roots in the soil and 1/3 exposed on the soil surface. 4. Excessive nitrogen fertilizerReason: During the fertilization process, the nitrogen fertilizer content is high, which can effectively promote the growth of the plant's leaves to be stronger, but it does not bloom. Solution: When summer comes, use potassium fertilizer, or use potassium fertilizer as the main fertilizer. Use nitrogen fertilizer in spring, but also pay attention to its concentration. |
