Fertilization. Ferns are relatively light feeders compared to many other foliage plants. They prefer a balanced fertilizer, such as 20-10-20 or 20-20-20, with micronutrients applied at approximately 200 ppm nitrogen. Too much nitrogen can cause tip burn on the roots and leaves if the plant becomes dry.
