Growing vegetables indoors during the winter is possible when using containers. The challenge is finding the correct varieties for your home. A large window that has good sun coverage is a requirement, as well as controlled heat to prevent vegetables from suffering in the cold. There are a variety of containers available for winter gardening, including clay, wood, plastic and metal.
Fill your container with growing media until it is one inch from the top. The University of Arizona recommends using a lightweight potting mix. Clay soil from the garden should be avoided, as its bad qualities in the garden are exaggerated in the container. Water the potting media before planting.
Sow the seeds of your vegetable in thin, shallow rows and cover the row with vermiculite. Cover the container with a clear plastic bag or with a humidity dome. This retains moisture and heat and speeds up germination. As soon as the seeds sprout with two true leaves, the plastic bag or humidity dome is ready to remove.
Transplant seedlings to new containers, digging up the plant using a sharp knife and placing in a new container at the same depth as it was growing in the previous container.
Place the plant in a large window that gets plenty of sunlight. Most fruiting vegetables need 80 degrees F during the day and 65 degrees F at night, says Utah State University. The University of Arizona recommends the plants get 8 to 10 hours of sunlight per day.
Fertilize the plants every two to three weeks using a water-soluble, complete fertilizer. If using a potting soil with fertilizer added the plant will not need nutrients for the first eight to 10 weeks, according to the Virginia Cooperative Extension.
