Indoor ferns are evergreen foliage plants which do not produce flowers or seeds. Some originate from tropical and subtropical climates, but you also find many from more temperate climes. The former types do well in warmer spaces - whereas the latter do much better in cooler temperatures. All ferns love moisture and don't enjoy drying out. Finding the best combination of light, moisture and temperature is the key to a happy fern.
• Ferns enjoy dappled light in their natural environment, so place in a spot where they get at least some bright light in the day - never in full, direct sunlight though. Some ferns are tolerant to shadier spots, but no fern will enjoy being in a dark, lightless space.
• Keep the soil quite evenly moist from Spring - Autumn, never waterlogged. Spray the leaves occasionally to create some humidity. You could also sit your pot on a tray of wet pebbles to create a similar effect.
• In Winter, if you are in a centrally heated space, continue your watering regime, with more frequent leaf spraying to compensate for the drier air. If you are in a cooler space you will find your ferns stays moister longer so you probably won't have to water them so often over this period; however do not position in temperatures below 10-12 'C over Winter.
• Repot if necessary in Spring using a moisture retentive compost. Feed every 2-3 weeks in the growing season (Summer) with an all purpose plant food.
