How to fertilize the red spider lily? Can urea be used to fertilize the red spider lily?

1. How to fertilize

1. Fertilization during the growing period: Red spider lily needs sufficient nutrients during the growing period so that the plant can bloom better. Generally, fertilizer should be applied every 15 days. Use dilute cake fertilizer water to supplement the plants with a variety of nutrients. Before applying fertilizer, be sure to dilute it to ensure that the concentration is within a safe range and does not cause any fertilizer damage to the plants.

2. Stop fertilizing during the dormant period: Red spider lily will enter a dormant period in summer and winter. During these periods, the growth rate of the plant will be restricted, and its ability to absorb water and nutrients will also be weakened, so there is no need to fertilize it. Once fertilizer is applied, it will accumulate in the soil, and when it reaches the growing season, it will cause fertilizer damage and be detrimental to its growth.

3. Fertilizing during repotting: In addition to the growing period, fertilizer should also be applied when repotting the red spider lily. At this time, choose more organic fertilizers, and use slow-release organic fertilizers. This fertilizer can continuously provide nutrients, increase soil fertility, and is more conducive to plant growth. If it is a quick-acting fertilizer, it will be absorbed quickly. Although the plant will grow quickly at the beginning, it will grow poorly later.

2. Can urea be applied?

Urea cannot be applied to red spider lily. Urea is a fertilizer with a high nitrogen content, but this plant's demand for nitrogen is very limited. Usually the concentration of nitrogen fertilizer should be controlled at only about 1 gram per kilogram. The nitrogen content in urea obviously exceeds the standard, and it is difficult to reduce the concentration by dilution. Excessive nitrogen will cause the plant to grow too tall, the flower stems will become longer and fall over, and it will also affect its flowering.
