Growing vegetables isn't just for farmers or folks with big backyards anymore. All you need are some large pots, sunshine and water and you can have a bountiful harvest right on your deck or patio. Use the largest pots that you can find for your container vegetable garden, at least 12 inches in diameter. According to horticulturists at the University of California at Davis, an additional 2 inches in pot depth can double your vegetable yield. Then, make sure you choose vegetable plants that will grow well in your area.
Choose vegetable varieties that grow well in pots. Although most vegetables can be grown in containers, tomatoes, squash, beans, carrots, eggplant, radishes, lettuce and peppers are the most common.
Pour the potting mix into the pot, leaving room for your plant so that, when planted, it will sit 1 inch below the rim of the pot. An exception is tomatoes --in that case, place the stem of the plant at least 2 inches into the soil.
Water the plant when the first inch of soil is dry to a finger poked into it. Water deeply, until the water runs out of the bottom of the pot.
Provide adequate sunshine for your vegetables. Most types of vegetables need a full day of sun. Leafy vegetables such as lettuce can tolerate partial shade.
Fertilize your plants for the first time two weeks after planting and then every twi weeks after that. Use fish emulsion or other organic fertilizer, according to the package directions.
