## Top 50 Companion Planting Pairs

Each pair lists the two crops, the type of benefit, and the biological mechanism. All data from the Plant Anywhere companion planting engine (489 total relationships).

Interactive companion planting chart: https://plantanywhere.net/companion-planting

### Pest Deterrence Pairs

4. **Cabbage + Dill** — Dill attracts parasitic wasps (Trichogramma) that prey on cabbage worms.
5. **Cucumber + Nasturtium** — Nasturtiums trap aphids, drawing them away from cucumber vines.
6. **Pepper + Garlic** — Garlic's allicin repels aphids, spider mites, and Japanese beetles from peppers.
7. **Tomato + Garlic** — Garlic deters red spider mites and aphids; volatile compounds reduce pest pressure on tomatoes.
8. **Rose + Garlic** — Garlic planted around roses repels aphids and Japanese beetles.
9. **Strawberry + Borage** — Borage deters strawberry pests and attracts predatory insects.
10. **Cabbage + Nasturtium** — Nasturtiums act as a trap crop for cabbage aphids.
11. **Lettuce + Chive** — Chives repel aphids from lettuce.

13. **Tomato + Asparagus** — Tomato plants repel asparagus beetles.
14. **Squash + Nasturtium** — Nasturtiums trap squash bugs and cucumber beetles.
15. **Bean + Rosemary** — Rosemary deters bean beetles.

### Nitrogen Fixation Pairs

16. **Corn + Bean** — Beans fix atmospheric nitrogen via Rhizobium bacteria, feeding nitrogen-hungry corn.
17. **Tomato + Bean** — Bush beans fix nitrogen that tomatoes need for fruit production.
18. **Cabbage + Bean** — Beans provide nitrogen for heavy-feeding brassicas.
19. **Squash + Bean** — Part of the Three Sisters system; beans fix nitrogen for squash.
20. **Potato + Bean** — Beans fix nitrogen for potato tuber development; potatoes repel Mexican bean beetles.
21. **Corn + Pea** — Peas fix nitrogen; corn provides a natural trellis for climbing peas.
22. **Cucumber + Pea** — Peas fix nitrogen for cucumber vines.
23. **Beet + Bean** — Beans provide nitrogen for beet root development.
24. **Spinach + Pea** — Peas fix nitrogen; spinach benefits from the enriched soil.
25. **Kale + Bean** — Beans provide nitrogen for this heavy-feeding brassica.

### Pollination Support Pairs

26. **Strawberry + Borage** — Borage flowers attract bees that pollinate strawberry blossoms, increasing fruit set.
27. **Tomato + Borage** — Borage attracts pollinators and repels tomato hornworms.
28. **Squash + Sunflower** — Sunflowers attract pollinators essential for squash fruit set.
29. **Cucumber + Sunflower** — Sunflowers attract pollinators and provide a trellis for cucumber vines.
30. **Pepper + Calendula** — Calendula attracts hoverflies and bees that pollinate pepper flowers.
31. **Zucchini + Marigold** — Marigolds attract pollinators needed for zucchini fruit set.
32. **Melon + Borage** — Borage attracts bees for melon pollination.
33. **Bean + Sunflower** — Sunflowers attract pollinators; beans can climb sunflower stalks.
34. **Eggplant + Calendula** — Calendula attracts beneficial insects for eggplant pollination.
35. **Pumpkin + Sunflower** — Sunflowers attract native bees critical for pumpkin pollination.

### Microclimate Modification Pairs

36. **Lettuce + Tomato** — Tomatoes shade lettuce from midday sun, delaying bolt by several weeks in warm climates.
37. **Lettuce + Corn** — Corn provides afternoon shade for heat-sensitive lettuce.
38. **Spinach + Corn** — Corn shades spinach, extending the harvest window in zones 7+.
39. **Radish + Squash** — Squash leaves shade soil, retaining moisture around shallow-rooted radishes.
40. **Lettuce + Sunflower** — Sunflowers provide partial shade and windbreak for lettuce.

### Multi-Benefit Pairs (Classic Combinations)

41. **Corn + Bean + Squash (Three Sisters)** — Corn provides a trellis for beans, beans fix nitrogen, squash shades soil. The oldest documented companion planting system.
42. **Tomato + Carrot** — Carrots loosen soil for tomato roots; tomato shade extends carrot harvest.
43. **Onion + Lettuce** — Onions repel pests; lettuce fills space between slow-growing onion rows.
44. **Onion + Beet** — Onions repel pests; beets and onions have compatible root depths.
45. **Onion + Tomato** — Onions deter aphids; both thrive in similar conditions.
46. **Celery + Cabbage** — Celery's scent confuses cabbage moth; both prefer cool weather.
47. **Radish + Cucumber** — Radishes mature quickly, breaking soil crust before cucumber vines spread.
48. **Pea + Carrot** — Peas fix nitrogen; carrots fill the space beneath pea trellises.
49. **Corn + Cucumber** — Corn provides a windbreak and partial trellis for cucumber vines.
50. **Garlic + Strawberry** — Garlic deters aphids and fungal disease around strawberry beds.

### Key Antagonist Pairs (Avoid Planting Together)

- **Fennel + most vegetables** — Fennel is allelopathic; root compounds inhibit growth of tomatoes, beans, peppers, brassicas.
- **Onion + Bean** — Alliums inhibit legume growth.
- **Garlic + Bean** — Same allium-legume antagonism.
- **Potato + Tomato** — Both nightshades; share late blight (Phytophthora infestans).
- **Cabbage + Strawberry** — Brassicas out-compete strawberries for nitrogen.
- **Dill + Carrot** — Cross-pollination risk (same family, Apiaceae).
