Growing fruits and vegetables in hanging pots turns small spaces into gardens. It also eliminates the need for weeding, staking and shooing away animals that want to eat your crops. Tomato cultivars like Tiny Tim, Cherry Gold, Small Fry and Patio Hybrid are sturdy, determinant plants that adapt well to container gardening without outgrowing their pots. The plants will be ready for harvest within a couple of months of when you first hung them outside.
Start tomato seeds indoors in peat pellets during the last two weeks of March if you don't intend to use plants that are already started. Plants will be ready to move outside in May.
Fill the hanging pot 3/4 full. Use a combination of one part each perlite, sphagnum moss, potting soil and compost. Pots should have drainage holes so the roots of the plant don't drown. If your pot has large holes, put a layer of small stones on the bottom to keep the soil from escaping.
Follow the label directions and add a slow-release fertilizer like 17-17-17 to the soil that's recommended for hanging tomato plants.
Set a tomato plant in the center of the pot. Cover the root ball with soil and press it down gently.
Water the plant thoroughly and add more soil if the soil in the pot settles below the top of the root ball. When you're finished, the soil should reach to within 3/4 inch of the rim of the container. Don't fill the container to the top.
Hang the plant in a location where it will receive full sun for at least 50 percent of the day. Water the plant when the top inch of the soil is dry.
Start fertilizing the potted tomato plant in July. Use water-soluble 5-10-10 or 10-10-10 mixed in water once a week. Read the package instructions for the proper proportions.
Harvest tomatoes as they ripen. The plant will produce more tomatoes because the ripe tomatoes won't be using the plant's resources.
