The fern likes loose and fertile calcareous soil. The family can use: garden soil + rotten leaf soil + sandy soil, and mix them according to the ratio of 4:5:1. If you want to grow well, you can sprinkle lime powder in the basin soil to increase the calcium.
Adiantum is fond of fertilizer, but there is little demand for fertilizer. Spring, summer and autumn are the growing seasons, and thin liquid fertilizer is applied once every 30 days. Ferrous sulfate solution can be irrigated 2-3 times a month.
Pay attention to the appropriate supplement of calcium fertilizer, so that the growth of Adiantum will be better.
The temperature is high in summer, so fertilization should be minimized. In autumn, the temperature gradually decreased, and in the middle of October, the fertilizer was gradually stopped.
Pay attention to the application of fertilizer, apply slowly along the basin mouth with a fine spout, do not let the fertilizer liquid touch the leaves, otherwise it is easy to burn the leaves and affect the viewing effect.
Adiantum prefers a warm and semi overcast environment. During the growing period, water is poured once a day. In summer, it is relatively hot. Water is poured once a day in the morning and evening. Meanwhile, water is sprinkled around the leaf surface and the basin to improve the air humidity and keep the leaves green. If there is no one at home, you can put the flowerpot on the wet sand table to make up for the water, which can be watered once every 2-3 days.
When the temperature is low in late autumn, winter and early spring, the basin soil is suitable to be wet, and the surface of basin soil is not allowed to dry.
Although Adiantum is a shade plant, it needs a certain amount of light in the growing season. Indoor maintenance, the best place in the east or north of the balcony, its light level is ideal.
shade is needed at noon in summer, and light should be seen properly in the morning and evening. If the light is too strong, the leaves of Adiantum can be zoomed. If it is planted on the outdoor balcony, it should be shaded at noon all the year round to prevent the leaves from burning and turning yellow.
In order to keep green, the growth temperature of Adiantum is 15-20 ℃ and the temperature in winter is no less than 5 ℃. In midsummer, if the temperature is too high, spray water on the plants every day to increase air humidity and cool down.
Adiantum should be planted in spring or changed basin soil. When changing the basin, pay attention not to damage the root system, avoid wind blowing, and replace half of the new soil. Keep the basin soil moist and appropriate air humidity after changing basin.
Because the leaves of Adiantum grow fast, in the growing season, some old leaves are often cut off. When the leaves are too dense, the fern not only loses its elegant form, but also the new leaves growing inside it will die due to the lack of light, which is easy to form hollow phenomenon, so it needs to be pruned in time.
When the withered leaves are found in the process of maintenance, they should be cut off in time to keep the plants fresh and beautiful, and to facilitate the germination of new leaves.
