The culture method of bird's nest fern

1. Peat soil or rotten leaf soil is the best soil for planting potted bird nest fern. The growth depends on planting nest fern for 2-3 years, the plant shape is open, and the root is full of pot rack, which can be protruded from the basin, and some residual roots and spore leaves withered at the base can be removed, taken out in the plant and replanted in the pot respectively. When changing the basin in spring, rotten leaf soil and moss should be added to the basin, and a little gravel should be added.
