Usually either semi-tropical or tropical plants which are grown indoors are called Houseplants. These plants are usually grown for decorative purposes. Certain important factors such as moisture, soil mixture, humidity, potting, light, temperature, fertilizers and pest control must be considered when growing a houseplant.

A houseplant can survive neither over-watering nor under-watering. Plans grown in pots require a certain level of dryness before being re-watered. This amount varies with each type of plant.

Two major factors to be considered for lighting of houseplants are duration and intensity of lighting. This varies with the type of plant. The duration of exposure is equally important as the intensity. Most plants require light exposure for 8 to 16 hours. As such, windows are the most common source of lighting for most houseplants.

Special soils called potting soil or compost is required for growing houseplants, since they cannot be grown in local soil. An ideal compost contains soil conditioners for providing the plant with proper nutrients, adequate drainage, support and good aeration.

Most houseplants can survive in the temperature range of 15 to 25 degree Celsius. These plants grow best in 80pc humidity, and since most homes have a relative humidity of around 60pc this would be ideal.

In order to maintain the plant properly, the potting used for a plant requires to be changed every two years.
