The mastiff fern is mainly reproduced in different branches.The division should be carried out in conjunction with repot before the new sprouts germinate in spring.Pull out the plants that are full of pots from the pot, break off most of the old culture soil, cut off their rhizomes, divide them into two to several clusters, and pot them separately, so that they can become new plants.In addition, the spores of the meridian fern mature and scattered in a warm and humid environment to reproduce and grow by themselves. When they grow to a certain extent, they can also be potted.

The iron wire fern likes loose, permeable and fertile calcareous soil and sand loam. When planting pots, the cultured soil can be mixed with equal amounts of loam, leaf dehurt soil and river sand.Apply liquid fertilizer once a week during the growth period, pay attention to keeping the pot soil moist and high air humidity regularly.In the dry season, water can be frequently sprinkled on the ground around the plants to increase air humidity.The iron wire likes bright scattered light and avoids direct sunlight.The light is too strong, the leaves are yellow and even die.It likes warmth and is cold-resistant, with a suitable temperature of 13-22, and a winter temperature of 5 in winter.
