Information on Keeping an Indoor Garden

Overview

If indoor gardening were simple, we could all run botanical gardens; in reality, there are no "house" plants. Keeping plants inside requires a complete set of accommodations to meet each plant's natural requirements.

Light

Low-light foliage plants require bright interior light. Supply supplemental artificial light for others with a mix of fluorescent and incandescent lamps a few feet above plants for 4 to 16 hours a day. Flowers and vegetables need 4 or more hours of sunlight each day.

Water

Keep most houseplant soil moist to offset dehydration caused by central heating and air conditioning. Use unsoftened tap water to avoid salt deposits. Before using city water, vent chlorine by letting it sit overnight.

Soil

Light potting mixes allows better drainage. Bake homemade potting soil or use sterile "soil-less" mixtures. Fertilize with half-strength liquid.

Containers

Containers should be large enough for root systems, drain well and be composed of materials that will not rot or leech chemicals into the soil.

Climate

Grow plants with similar cultural requirements together on a tray; they will establish their own "microclimate." Temperatures of 70 to 80 degrees Fahrenheit during the day and 10 degrees cooler at night suit most plants.

Pests

Whiteflies, mealy bugs and thrips are some of the pests that can enter the indoor garden on plants or in new potting soil. Quarantine new materials and use insecticidal soaps for control.
