Strawberries are a popular summer crop, but once the weather changes fresh berries can be very hard to come by. For gardeners who can't get enough of this sweet, red fruit, strawberries can be grown indoors, as long as adequate lighting is provided. Try your strawberries in hanging baskets under grow lights for best results.
Line the basket with sphagnum moss. It should be fairly thick on the bottom but can be thinner on the sides. Fill the basket the rest of the way with potting soil. Water until the soil is soaked and allow it to drain.
Trim the roots of the strawberry plants so that they are no more than 5 inches long. Remove any damaged or diseased sections.
Plant the strawberry plants in the soil. Spread the roots out so that they are not bunched up before you cover them with soil. Bury the roots up to where they join at the stem. Don't overcrowd the basket, as the plants need room to grow and spread.
Place the grow light near the strawberry plants. Hang it above them or place it on a stand near them. Follow the manufacturer's instructions for the correct distance from the light to the plants. It is important to use a full-spectrum grow light, as the strawberries will not develop or ripen without the proper kind of light.
Expose the plants to light for at least eight hours per day, though the light can be on up to 16 hours, if you choose. The plants need a rest period where there is no light for at least eight hours each day. If the strawberries are placed in a location where they get as much sunlight as possible the need for artificial lighting is reduced.
Tap the flowers gently with the paintbrush, going from one to another, to spread the pollen throughout the blossoms. Strawberries are self-pollinating, but though that means you can get berries from a single plant, when grown indoors they still need some help spreading the pollen from flower to flower. Otherwise there will not be any fruit.
Water the berries whenever the soil gets dry. Fertilize lightly once a month. Avoid getting berries wet, to minimize potential fungus problems.
