You don't need a plot of land to grow fresh vegetables. Many vegetables lend themselves well to container gardening. With some thought to selecting bush or dwarf varieties, almost any vegetable can be adapted to growing in a pot. Vegetables that take up little space, such as carrots, radishes and lettuce, or crops that bear fruits over a long period of time, such as tomatoes and peppers, are perfect for container vegetable gardens.
What you can grow in a container vegetable garden is limited only by the size of the container and your imagination. How about a Summer Salad container? Plant a tomato, a cucumber and some parsley or chives all in a large (24-30") container. They grow well together and have the same water and sun requirements. By late summer they might not be very pretty, but they'll keep producing into the fall. This makes a great housewarming present, too.
Selecting Containers: Containers for your vegetable gardens can be almost anything: flower pots, pails, buckets, wire baskets, bushel baskets, wooden boxes, nursery flats, window planters, washtubs, strawberry pots, plastic bags, large food cans, or any number of other things.
Containers and Pots for Vegetable Gardens
Drainage: No matter what kind of container you choose for your vegetable garden, it should have holes at the base or in the bottom to permit drainage of excess water.
Color Considerations: You should be careful when using dark colored containers because they absorb heat which could possibly damage the plant roots. If you do use dark colored pots, try painting them a lighter color or shading just the container, not the plants.
Size: The size of the container is important. For larger vegetables like tomatoes and eggplants, you should use a five gallon container for each plant. You can grow these plants in two gallon containers, however you need to give the plants considerably more water.
You can use soil in your container vegetable garden, but potting mixes are much better. Peat-based mixes, containing peat and vermiculite, are excellent. They are relatively sterile and pH adjusted. They also allow the plants to get enough air and water. Mixing in one part compost to two parts planting mix will improve fertility.
Soil and Fertilizer
Using a slow release or complete organic fertilizer at planting will keep your vegetables fed for the whole growing season.
