Most vegetables, like peppers and tomatoes (above), grow well in containers
Containers
You can use just about any container for your plants, shrubs, trees and vegetables. Planter boxes, wooden barrels, hanging baskets, old leather boots and large flowerpots all make great containers. Lettuce, greens, spinach, herbs, onions, carrots and Summer Squash all grow well in pots. Try to position containers so your vegetables and herbs will get at least 6 hours of sunlight daily. Plants growing in containers need regular feeding and watering. A trellis or vertical support is perfect to assist trailing vegetables like beans, peas and cucumbers.
Tomatoes grow best in containers of at least 12" or 18" deep (one plant per pot); peppers grow best in 12" deep pots (1 to 2 plants per pot). Greens, such as lettuce and spinach, have shallow roots and thus do well in broader, flatter containers.
Companion planting mixes different complimentary crops together
John Adamson's Tip of the Week
Companion planting
Companion planting is the mixing of different crops close together, on the premise that they help each other out in nutrient uptake, pest control, pollination, and other factors essential to a good crop yield. For us gardeners, the combinations of different plants also make for a more diverse, attractive vegetable garden, as well as allowing more prolific use of space. It's a good idea to grow plants with a strong aroma around your vegetables as they will deter unwanted pests.
By planting these you will repel Aphids, Carrot Fly, slugs, Cabbage Fly, Spider Mites, ants and various other pests. Some of the easiest plants to mix into your vegetables include: Nasturtiums, Stock, Onions, Marigolds, Tagetes, Violas, Batmix, Butterfly Mix or Bumble Bee Mix flowers. The most important thing to take into consideration is not to plant anything that grows over ten inches as it will only compete for light and nutrients with your vegetables.
