Vegetables can be grown in containers as well as in the garden. Container gardening allows for growing vegetables in areas where there is little or no yard space for a garden, as well as for increasing the ability of the yard to produce vegetables. A good size container can vary from a decorative pot about a foot wide to a whiskey barrel. The following plants do very well in containers.
Container vegetables need to be watered more frequently and fertilized regularly to make up for the conditions of being in the pot. A monthly or weekly fertilizer routine will work, as will time-release fertilizers. These can be bought at a local garden center. Organic matter can be added to the soil every year to enrich it.
All vegetables grown as greens: Lettuce, spinach, collards, Swiss chard, and any other green leafy vegetable grow well in pots. The plants are generally smaller in size and can withstand the limited soil well. Harvest the outer leaves, leaving at least two thirds of the plant at all times. When plants start to bolt, harvest the entire plant before the crop is ruined.
Radishes: Radishes are a spring and fall vegetable that matures quickly and does not need a lot of room to grow. Radishes can be grown with other vegetables and harvested, allowing the other vegetables to take over the pot as they expand.
Tomatoes: Patio tomatoes and similar tomato varieties that are bred specifically for growing in pots will do well in most pots. Any tomato will grow in a pot, but it will often need a support system such as a tomato cage lest it sprawl. If the pot is not large enough, the plant will become cramped and cease productivity.
Cucumbers and summer squash: Cucumbers can be grown in pots if given a trellis and trained up it. They will require a larger pot or fertilizer but will bear fruit as long as those needs are met. Summer squash and zucchini can grow in larger pots, but will fill the pot with their foliage.
Beans and peas: Bush beans can be grown in pots. If pole beans are grown, provide a pole for support. Beans will remain throughout the entire season. Peas can also be grown in pots. Peas mature in early summer and then die, so plant with other vegetables that will take over the pot as the peas die.
These are some of the many vegetables that can be grown in pots. Generally, if the key needs of water and nutrients are met, the plant should grow well provided the pot and the area it is in meet the size and growth habits of the selected plant.
