Whether you want fresh vegetables during the winter, or you lack outdoor gardening space, an indoor container garden can meet your needs. Many edible plants can be grown indoors with proper light and care. In most cases, a southern-facing window is a requirement to harvest your indoor garden crop.
Herbs can be grown indoors, in a sunny room, preferably with southern exposure. Some popular herbs to grow indoors include basil, parsley, oregano, mints, chives, parsley and rosemary. In addition to plenty of sun, herbs require good drainage, temperatures below 70 degrees and fertilization. Trimming the herbs regularly will help the plant live longer, by preventing flowering.
Citrus fruits like lemons, limes and mandarin oranges can be grown indoors. Often these trees are grafted. Bright light is required and so is good drainage. Large plastic containers can be used, but they absorb a lot of heat from the sun. This heat can damage the roots. Wooden containers can be used, but the wood should be treated to prevent rotting. Frequent watering and regular feeding will help the plant thrive.
Tomatoes, peppers, lettuce and radishes can be grown indoors on a well-lit windowsill. A supplemental fluorescent light may also be required. When grown indoors, these plants will grow slower than their outdoor counterparts. The best way to water indoor vegetables is to set the pots in trays of water and pebbles. This helps keep them watered and also provides humidity. The best varieties of tomatoes are Tiny Tim, small fry and Roma.
