Prof. Martin Thorne, Ph.D.Selecting the ultimate companion plants for tomatoes turns your garden into a vibrant ecosystem. These friends provide chemical-free pest control and help with pollination. I've had tomatoes explode when I chose the right companions. Companion Plants can support stronger plants without the use of chemicals.
Basil is a superstar, a great companion for tomatoes. It has a strong scent that repels whiteflies while enhancing the flavor of tomatoes. Plant 2-3 basil plants next to each tomato plant, at a distance of 8-12 inches apart. Using basil with tomatoes is known to increase yields by 15-20%, thanks to root interactions.
Marigolds prevent nematodes from attacking tomato roots. The chemicals in the roots suppress detrimental pests for months at a time. French marigolds are most effective when planted among tomatoes, forming a living barrier against soil diseases.
Garlic
- Repels spider mites with natural antifungal properties
- Prevents soil-borne diseases through root exudates
- Plant cloves 6 inches from tomato stems
Borage
- Attracts bumblebees for superior buzz pollination
- Accumulates potassium and calcium for soil enrichment
- Self-seeds for continuous seasonal coverage
Nasturtiums
- Serve as trap crops luring aphids away
- Emit airborne compounds repelling whiteflies
- Edible flowers add peppery flavor to salads
Borage brings essential pollinators to your garden. Its blue flowers attract bumblebees, which buzz-pollinate tomatoes. This unique process significantly increases fruit set, plant borage early for continuous blooms.
Create beneficial microclimates with smart pairings. Tall sunflowers provide afternoon shade in hot regions. Low growing thyme acts as living mulch. These combinations naturally regulate temperature and moisture.
For effective combinations, group companions together in a beneficial way. Plant garlic or onions next to your tomatoes, accompanied by basil and marigolds, for extra protection against pests and diseases. Your tomatoes will repay you by producing leaves and fruit for a plentiful harvest.
