For container gardens, choose vegetable varieties that stay small. Obviously, a giant squash or pumpkin plant may spread more than ten feet and may not be the best candidate for a patio planting. Smaller plants such as onions, lettuce, cabbage, carrots (short varieties), eggplants, peppers, radishes, or even summer squash make good options for patio gardens.
Many vegetables, like radishes, carrots, beans, and lettuce grow quickly. Consider succession planting for continuous production – after harvesting one vegetable, plant another in its place.
Some small winter squashes and melons will adapt to container growing. Certain vine crops can be found in a bush or a patio variety. To grow tomatoes or cucumbers, limit your planting to patio tomatoes and patio or bush cucumbers. If the tomatoes and cucumbers are trellised or trained to cages, larger vines may be used, although some hand pruning of excess foliage may be necessary to increase yields. Plants can also be tied to stakes using soft ties such as rags. Place ties just below the blooms for optimum support. You might try placing containers along a fence or rail that will provide support for cucumbers and other vine-type plants.
Strawberries adapt well to container growing. A barrel, strawberry pot, or large container is best for strawberries. Tall pots make excellent vertical gardens. Plant the strawberries through holes in the sides of the container, and provide them with adequate water and fertilizer.
If containers are not in a protected location, consider placing a support by them to keep them from tipping over in the wind.
All vegetables and fruits need a minimum of six hours of sunshine a day. Devoted gardeners may consider moving pots around to take best advantage of available sunlight.
