Houseplants add natural color and beauty to a room. For apartment dwellers, houseplants may be the only gardening option. While most houseplants do not require as much sunlight or care as outdoor plants, they still need some easy care to produce flowers and foliage.
Line your pots in sphagnum moss for moisture retention. Soak the moss in warm water for one hour, place a 1-inch layer along the entire inside of the pot and press it firmly into place.
Fill your pots with sterilized potting soil. Outdoor garden soil or dirt often contains high amounts of bacteria and insect larva.
Fertilize the plants every eight weeks. Mix quick-dissolving fertilizer, per package instructions, in a watering can full of water for ease of application.
Water your plants only when the potting soil's top inch is dry. Over-watering will cause root rot in plants, creating unwanted odors and yellow or brown leaves.
