Ferns are relatively easy to grow; however, drafts, dry air and temperature extremes won’t help. Ferns that are pampered and protected from things like dry air and temperature extremes will reward you with lush green fronds all year round, beautifying your indoor garden more than you could imagine. Let’s learn more about growing ferns indoors. Tips for Growing Ferns Indoors There are a lot of species of tropical and subtropical ferns, but there are also a lot of ferns that are native to more temperate climates. These ferns would be well suited to cooler parts of the house but won’t survive in rooms that are too well heated. Tropical ferns survive best in homes with central heating. Below are recommend indoor conditions for optimal fern growth: Humidity All ferns love moisture and should be given humid conditions. In living rooms and family rooms, stand their pots on trays of damp pebbles or clay granules. Ferns also love being misted at regular intervals with tepid, soft water unless the humidity of the whole room is kept high through the use of a humidifier. Compost/Soil You also need to provide the right compost. Most ferns are forest or woodland plants and have tender, delicate roots adapted to the light forest soil, which is rich in leaf mould and decayed vegetable matter. The right compost must be free draining so that the roots never get waterlogged. A compost that contains peat or a fibrous peat substitute with plenty of sand is best. The compost should never be allowed to dry out, which may mean watering the plant a little every single day in a warm, dry atmosphere. Light Although most ferns grow in moist shady places like forest floors, this does not mean that they need no light. Their normal situation in the wild is dappled light, and if the light level in the home is too low, you will see poor growth and yellowing fronds. Give your ferns a position near a window that gets morning or late afternoon sun, and keep the ferns away from strong sunlight, especially during the summer. Direct sunlight will make them lose their leaves or turn their fronds yellow.
