Having planted the plants in separate pots, they are placed in a warm, bright place, previously covered with a plastic bag. Periodically remove the package, water the soil and spray the foliage.
When propagating by shoots, it is pressed against the substrate in a separate pot with a wire. The soil is kept moist until the young leaves begin to appear on the rooted shoot. After that, the plant is planted in a new pot and the usual care of nephrolepis is continued.

Poor fern growth is often associated with improperly selected soil, it should be light so that moisture does not linger and does not interfere with the active development of the root system.
Plant in winter. For the rest period, the temperature is reduced to 16 ° C and the watering is slightly reduced. A flowerpot with a flower should not be near heating appliances.
