In nature, where plants grow without cultivation, there is always a mixture of plant types growing in an area. The selection of the plants living in an area depends on the soil type, local climactic conditions, and horticultural history.
With few exceptions, the plants that grow together in the wild are mutually beneficial in that they allow for maximum utilization of light, moisture and soil. Plants needing less light live in the shade of those which must have full light, while the roots of some plants live close to the surface and others send their roots far down into the ground. This is known as Companion Planting.
Companion planting enables gardeners to make maximum use of sun, soil and moisture to grow mixed crops in one area. Companion planting also helps reduce bugs and pests in the garden.
Some plants have a beneficial effect upon the garden because of some peculiar characteristic of their growth, scent, or root formation and soil demands. Odoriferous plants (the smelly ones), including those with aromatic oils, play an important part in determining just which insects visit the garden. But while some plants can repel insects, they can also hinder the growth rate of other plants or otherwise adversely affect them.
You can plant a Vegetable Garden in very small places ... right up to very large ones. These pictures are examples of Companion planting along a sideway, up to a large backyard. You are only limited to your imagination when choosing your veggie garden spot.
This is a "Country Style" Veggie Garden with Companion plants.
Isn't this just beautiful. It is well planned out, with easy access to all the veggies and flowers. The garden seat covered over with a vine is a great place to sit and enjoy your work. Using grass as pathways has created a very homely veggie garden. As I wrote earlier, your veggie garden is only limited to your imagination (and the space you have available)
