The way you sow your vegetable garden is essential. Try not to plant vegetables in large patches or long rows; instead, mix in flowers and herbs. The large groupings of one type of plant will attract problematic pests. If you mix in flowers and herbs, it becomes more difficult for pests to find your veggies. The scent of flowers and herbs, as well as the change up in color, is thought to confuse pests.
A common companion planting article references the Native American “Three Sister Planting”. This type of planting involves growing corn, beans and squash – often pumpkin - in the same area. As the corn stalks grow, beans naturally find support by climbing up the stalk. Beans, as all legumes, fix nitrogen in the soil, which supports the large nutritional needs of corn. Squash grows rapidly and the large squash leaves shade out weeds and serve as natural weed block. Good plant companions work in support of each other.
A companion planting guide will show you which vegetables and flowers support or inhibit the growth of other plants and/or which pests they deter.
