Companion planting is a great way to enhance and protect your vegetable garden. The idea is not new, but it is still as relevant today as it was 200 years ago. Native Americans used companion planting to raise corn, pole beans and squash. Each vegetable has an important role in this cooperative trio. The corn provides a trellis for the beans, the beans fix nitrogen for the corn, and the squash becomes a living mulch preventing weeds and prevents evaporation.
Your vegetable garden doesn’t need to have this perfect synergy to have great rewards. Just adding a plant that will deter invasive insects will be an environmentally rewarding result. An example of this would be planting radishes near cucumbers, peas or leaf lettuce. Radishes repeal the cucumber beetle.
Companion planting is not an exact science. Not all plants get along well together. You don’t want the plants to be competing for the same space or nutrients. Two shallow rooting plants fighting for the space space is not a good idea.
Square foot gardening allows for great execution of companion planting. Since the plants will already be close, you might as well take advantage of the benefits.
