The planting method of kidney fern requires higher temperature.

Kidney fern has shallow root distribution and poor absorptive capacity. It is necessary to choose soil with good drainage and irrigation conditions, rich in humus, sufficient fertility and soft soil, and then fertilize the soil. Kidney fern requires high temperature. The temperature control of 10-32 ℃ is the most suitable for the normal growth of kidney fern, and its growth temperature can not be lower than 5 ℃. In the process of growth, we should protect against cold and heat in winter, heat preservation in summer, and strengthen ventilation. Shortening the watering frequency and applying fertilizer reasonably are beneficial to improve its ornamental value.

1. Planting conditions

The nutrient absorption capacity of kidney fern is poor, its root distribution is shallow, and it also has a certain degree of gas. Kidney fern is suitable for planting in soil with sufficient fertility, good drainage and irrigation conditions, rich in humus and soft soil. Then apply sufficient base fertilizer to improve the soil quality, which is more beneficial to the growth of kidney fern and increase its yield.

2. Reasonable lighting

Kidney fern is a kind of shade-loving plant, which can grow with a certain amount of scattered light. Too strong light, direct sunlight will affect its normal growth, reduce its ornamental value, too strong light: lead to kidney fern leaves withered and yellow, serious will die, direct sunlight: lead to leaf water loss, withered and yellow. In order to maintain the good ornamental quality of kidney fern for a long time, we need to provide proper light and see light regularly.

3. Temperature

Kidney fern requires a high temperature, the temperature directly affects its normal growth, its temperature can not be lower than 5 ℃, too high temperature will lead to the growth of kidney fern, but also affect the growth of underground tubers and reduce its ornamental value. The temperature of 10-32 ℃ is the most suitable for the normal growth of kidney fern. In order to improve the ornamental value, we should do a good job of cold prevention and heat preservation in winter, heat prevention and cooling in summer, shorten watering frequency and strengthen ventilation.

4. Fertilization

Kidney fern does not need much nutrients in the growth process, it is a kind of fern without flowers and fruits. Generally in the spring and autumn growth period, fertilization twice a month, mainly nitrogen fertilizer, pay attention not to be too thick, excessive, otherwise it will lead to kidney fern fertilizer damage, weak growth, prosperous growth and other adverse phenomena. Therefore, we should apply fertilizer reasonably to ensure the gloss of kidney fern and improve its growth ability, so as to improve the ornamental value.
