Grow a variety of fruits and vegetables indoors for a fresh food supply throughout the year. You can grow most any vegetable indoors in a container and dwarf fruit trees, fruit shrubs, and strawberry plants do well potted indoors as well, sometimes producing a better and earlier crop because of the protection from outdoor elements. Give each plant a healthy start and provide it with elements that keep it healthy as it grows for a successful crop.
Pour 1 inch of gravel into the bottom of a container at least 1 foot in diameter and at least as deep. Fill the container with a premium potting soil.
Dig a hole with a small shovel in the middle of the container's soil as deep and wide as the root ball of the vegetable or fruit plant. Dig multiple holes if planting varieties that allow for more than one plant in the container, such as strawberries. Follow the spacing directions provided with the plant tag to determine if more than one plant will fit in the container.
Set the transplant in the hole and pack the soil lightly around the plant's root ball.
Set a cage in the soil around the plant if you plant vining varieties, primarily vegetables such as tomatoes, pepper, cucumbers or squash. Secure the cage by pushing it firmly into the soil.
Water the plants daily, unless the soil still feels moist.
Apply a fertilizer formulated for fruits or vegetables as often as required. Follow the application directions provided with the fertilizer to determine how and how often to apply. Many fruits and vegetables benefit most from fertilizer application when they are fruiting.
Repot in a larger container when fruit or vegetable plants begin to show signs that they are outgrowing their container, including obvious signs that the plant looks bigger than its container or roots growing through the bottom of the container.
Place plants in a sunny room, preferably a sunroom, where the plants will receive full sunlight throughout the day. To increase light exposure, which will encourage better growth, suspend grow lights 2 inches over the plants and move the lights up as the plant grows. Keep the lights on during the day, starting first thing in the morning, for about 16 hours per day.
