Adiantum is a perennial evergreen herb, also known as iron wire grass, maiden's hair, clematis, shuizhumaotu, guotanlong, black foot fern, Wujiao gun, black bone fern. Its light green thin leaves with dark bright petioles make it elegant and elegant. It is 0.1 ~ 0.5m high. Because of its slender stem and color like iron wire, it is called Adiantum. Adiantum is also an indicator of calcareous soil. Due to its fear of dry and strong light, it must be placed in a place without direct sunlight for maintenance. There are also many varieties of Adiantum, such as Adiantum reniforme and Adiantum reniforme. It belongs to the world species and is wild in all regions.
Adiantum preferred warm and humid environment, not resistant to cold and drought, suitable for acid soil. Potted plants can always be placed indoors with scattered light, then they grow well. The suitable culture soil for basin soil is the mixture of mountain forest soil and fertile garden soil. In the growing season, water should be sufficient, and thin fertilizer should be applied once every two weeks to promote its growth and prosperity. In summer, it should be kept outdoors under shade. When the foliage is too dense, the old leaves can be properly pruned, otherwise the leaves are easy to turn yellow and hinder the view. After winter, it is safe to move into the room and put it in the scattered light place, and keep the room temperature about 10 ℃.
In winter, the temperature is low, suffering from late frost or early frost. The suitable temperature for its growth is 15 ~ 24 ℃. If the room temperature is above 10 ℃ in winter, its leaves can keep green and turn black and yellow when it is lower than 5 ℃. Too much shade, no sunshine for a long time. Adiantum Adiantum is afraid of heat and can not be exposed to the sun, but it can not be completely shaded. In summer, it is better to put it under outdoor shade and trees, or move outdoors at night and move back indoors during the day. Light should be fully visible in winter. In summer, the climate is hot and stuffy, and the ventilation is poor. Air humidity should be increased and ventilation should be strengthened.
In order to raise a good family Adiantum, we should do the following:
① Adiantum likes warm, humid and semi cloudy environment, avoid direct sunlight. It's better to put the plant in the place where the sunlight can't reach indoors. Too much strong light will cause the leaves to wither and scorch. It grows well at 10 ~ 20 ℃ and is inhibited by high temperature in summer. It can be evergreen in winter when it is no less than 5 ℃.
② Ferns grow in humid environment, and Adiantum is no exception. In the cultivation, in addition to pay attention to keep the soil moist, but also often to the leaf surface water spray, in order to improve the air humidity, the plant appears yellow, is often caused by insufficient humidity. In addition, it may be freezing damage.
③ Change pots once a year in spring, pruning to remove dry leaves and old roots. Basin soil should be replaced with fresh, fertile and loose rotten leaf soil, and a small amount of brick chips should be added.
How to do with burnt edge of Adiantum?
The brown scorched edge of Adiantum Adiantum leaves is easy to appear, which is a common problem in cultivation. Adiantum was originally born in damp wall crevices or stone surfaces, and preferred to be moist. Because of the strong sunlight in summer, the Adiantum can not grow normally if it is not put in the shade environment. The direct sunlight will make the water in the leaves evaporate quickly. Before the roots can absorb the water, some cells of the leaves have dried and dehydrated, and the green color will gradually fade away, which will lead to scorched edges.
