If you have fern plants and other plants in your home and want to save a little money, you can make your own fern/plant food. You only need a few minutes and a couple of household items.
Pour one gallon of rainwater or distilled water into a bucket. Do not use tap water; it may contain harmful minerals and chlorine. The water should be room temperature.
Place 1 teaspoon of potassium nitrate, 1/3 teaspoon of ammonia, 1 teaspoon of Epsom salt and 1 teaspoon of baking powder into the gallon of water. Mix well. You now have homemade fern food that also works with other houseplants.
Pour the fern food into a watering can and sprinkle on your fern's soil until it is damp but not soaked. Feed your fern the mixture about every four to six weeks.
