Fern
Ferns make wonderful, low maintenance houseplants. When the leaves and fronds become dry and brown, they should be removed. Use porous soil that is rich in organic matter. Pot up only when severely root-bound. Don’t confuse the brown spots on the underside of the leaves, which contains spores, with insects.
Light
Ferns need to be place din medium, indirect light of an east-facing window.
Water
During active growth (spring and summer), plants should be watered on a regular basis in order for the soil to remain moist. Distilled water is preferred over tap water. it is recommended that the fern be allowed to become dry to the touch between times of watering in fall and winter months. Putting a potted fern in a basin of water so it can soak up the moisture naturally is an easy way to maintain proper watering. Your watering practices determine your success with ferns. over or under-watering are by far the most common reasons for poor results. Shedding leaflets occurs very rapidly if the plants are over or under-watered.
Fertilizer
For optimum plant health, fertilize with an all-purpose houseplant food April through October, following label directions. For all other months, fertilize half as often.
