Vegetable Companion Planting

Vegetable Companion Planting is the subject of many books and articles. According to Louise Riotte in her book Carrots Love Tomatoes: Secrets of Vegetable Companion PlantingCompanion Planting for Successful Gardening, “Plants that assist each other to grow well, plants that repel insects, even plants that repel other plants — all are of great practical use.  They always have been, but we are just beginning to understand why.”

The challenges of vegetable gardening in the greater Prescott area are many, from water to weather to soil composition.  So, we choose to utilize all potentially beneficial techniques even if not scientifically proven.  And, we recognize this is a departure from our commitment to offer science-based information.  As Louise Riotte indicates, this is part magic, part mystery and based on empirical findings.

We have created a chart which summarizes companion planting suggestions for many popular vegetables from Carrots Love Tomatoes for your reference.

Additionally, remember that you want to attract diverse pollinators to your garden. Planting a variety of flowering plants with varying bloom colors, blossom sizes, blossom shapes, and bloom season will attract the most pollinators to your garden.  Add water and shelter and you will have a habitat that encourages these beneficial critters.
