Bird's nest fern, also known as bird's nest fern, hawthorn flower and crown fern, is a perennial shade herb foliage plant of bird's nest fern of Adiantum family. Because the bird's nest fern likes water, it is better to keep the soil moist than dry, so keep it moist and don't set a fixed watering time.
When the temperature is high, you can water more, once a day or once every other day. In the low temperature environment, you can do it once every 3 to 5 days, so be flexible! When the temperature is between 15 ~ 26℃, it can be irrigated with dilute fertilizer water, which is very beneficial to growth.
Note: the bird's nest fern likes warm and humid environment and is not resistant to high temperature and cold. When it is higher than 30℃, spray more water and ventilate more! Hi high humidity environment, not dry! Please spray water frequently to increase the air humidity! In addition, although the bird's nest fern has strong shade tolerance, it also needs scattered light to grow better! Don't leave it in the dark for a long time! Of course, you should also prevent exposure when the sun is strong!
1. Peat soil or humus soil is the best soil for planting potted bird's nest fern. After growing for 2-3 years, the fern plant is planted in the nest, the plant shape is open, the roots are crowded with pots, so that it can be removed from the pots, some residual roots and withered spore leaves at the base are removed, taken out from the plants and replanted in the pots respectively. When changing pots in spring, humus and moss should be added to the pots, and a little gravel should be added.
2. Temperature and illumination The suitable temperature for the growth of the bird's nest fern is 22-27℃, and it should be shaded in summer, or placed in a shady place under a big tree to avoid direct sunlight, which is conducive to growth and makes the leaves shiny. Indoor should be placed in a bright place, not in the dark for a long time. In winter, it should be moved into a greenhouse, and the temperature should be kept above 65438 06℃ to make it continue to grow, but the minimum temperature should not be lower than 5℃.
3. Water fertilization Under the conditions of high temperature and high humidity in summer, the vigorous growth of new leaves requires more water spraying, full spraying of leaves and maintaining a high temperature, which is conducive to spore germination. With the increase of leaves, the leaves often cover the pots with culture soil, so water the pots thoroughly to prevent the leaves from drying and curling due to lack of water.
Bird's nest fern can be seeded with spores and propagated by ramets. Spore propagation has been widely used in commercial mass production. Generally, it can be propagated by ramets. When plants grow bigger, small branches will appear. Before the new buds are born in late spring and early summer, you can slowly cut off the plants that need to be separated with a sharp knife and then plant them separately. The bird's nest fern has few branches, so it is rarely divided into plants by the usual method of separating offspring. Usually, healthy plants are cut into 2-4 pieces from the base at the end of spring, and the leaves are shortened by 1/3- 1/2, so that each piece has some leaves and rhizomes, and then potted into new plants respectively; After potted, put it in a semi-shady place with a temperature above 20 and high air humidity for maintenance, so that the wound can heal as soon as possible. The medium in the pot is slightly wet, not too wet, otherwise it will rot easily. After the new leaves are born, they can gradually return to their original shapes.
