Boston Ferns prefer bright, indirect light, direct sunlight will burn the fronds. If outdoors, placing them in an area with morning sun is best, with protection from the afternoon sun. If you notice your fern is losing its vibrant color it may need more light.
The key to success with Boston Ferns is humidity. When indoors is it especially important to provide supplemental humidity for your plant to thrive. A humidifier, humidity tray and daily misting can all provide adequate humidity levels for Boston Ferns.
These plants also need to have consistently damp soil. Checking your plant daily and water when the top layer is dry, is key. When outdoors, your plant will most likely need water daily.
Boston Ferns should only be fertilized during the summer months. Use a 20-10-20 water-soluble liquid fertilizer at half strength monthly during the summer months.
