With their wide variety of leaf structure, ferns are among the most beautiful houseplants. Not only do they add a tropical feel to your indoor garden, ferns are among the best plants you can grow to help purify the air indoors. Ferns are relatively easy to grow if you provide them with what they need: medium to bright, indirect light, humidity and a room temperature of between sixty- and seventy-degrees Fahrenheit. In addition, it’s important to maintain a consistent soil moisture level with regular watering. Allowing the soil to dry out between watering will stress the plant. Consider investing in a soil moisture meter to help you maintain the right moisture level.
Ferns will also benefit from a light fertilizing a couple of times a month. Kelp is a good choice because it provides the low Nitrogen fertilizer that your ferns need during the winter months. Plan to use one to two teaspoons every other week to feed your plants. Supplement your fertilizing program with Super Thrive on the weeks that you don’t use Kelp. These two products emulate the nutrients that ferns would typically receive in their natural surroundings. Ferns do well when grown together or when combined with other houseplants. Clustering plants together helps raise the relative humidity, an important factor when growing ferns indoors. Adding a room humidifier or placing your plants on a pebble tray will also increase the humidity around your plants. Avoiding conditions such as dry air, drafts and temperature extremes will encourage your ferns to maintain their lush green fronds all year round.
While the Boston fern is easily the most recognizable, there are many varieties of ferns that will do well indoors, including Maidenhair, Bird’s Nest, Kangaroo Paw, Rabbit’s Foot and Staghorn. Ferns make beautiful houseplants, adding a tropical look to your indoor garden all year round.
