Fertilization cycle of kidney fern

On the one hand, the kidney fern has strong vitality, on the other hand, it consumes less nutrients. Sometimes it is still green without watering and fertilization for many days. Therefore, many flower friends will think that the kidney fern does not need fertilization. However, this idea is wrong. The kidney fern not only needs fertilization, but also needs to be fertilized every half a month. Winter can be an exception. The kidney fern does not grow vigorously in winter, so it can be fertilized once or twice a month.

Fertilizer composition of kidney fern

The fertilizer composition of kidney fern is mainly nitrogen fertilizer, and it is thin nitrogen fertilizer, which is also the reason why kidney fern is fertilized every half a month. The thin nitrogen fertilizer is easy to be consumed. If the nutrient content is too high, it will also affect the normal growth of kidney fern, and even bring fertilizer damage to kidney fern, so that kidney fern will be burned due to excessive fertilizer.

Key points of kidney fern watering

Keep the soil moist and do a small amount of frequent watering. In summer, the temperature is high and the water is easy to volatilize. Therefore, water should be poured twice or three times a day on average, and avoid watering at noon (watering at noon in summer will damage the pores of kidney fern). Generally, water in the morning and evening, mainly in the morning. The amount and frequency of watering in winter can be appropriately reduced. Firstly, the temperature is low in winter and there is little water evaporation. Secondly, the growth of kidney fern in winter is not as strong as that in spring and summer, and the demand for water is not much. However, it is necessary to keep it growing in a wet and cool environment and avoid watering in the evening. If the amount of water is not well controlled in the evening, it is easy to freeze at night and affect the normal growth of kidney fern.
