Companion planting is nature's way of creating harmony in the garden. By growing certain plants together, you can naturally repel pests, attract beneficial insects, and improve overall plant health.
Classic Companion Plant Combinations
Tomatoes + Basil: Basil repels aphids and improves tomato flavor Carrots + Chives: Chives deter carrot flies and save space Marigolds + Everything: These flowers repel nematodes and many garden pests Lettuce + Tall Plants: Use vertical space and provide natural shade
The Science Behind Companion Planting
Pest Confusion: Mixed plantings make it harder for pests to find target plants Beneficial Habitats: Diverse gardens attract predatory insects that eat pests Root Partnerships: Different root depths access various soil nutrients Chemical Warfare: Some plants release compounds that deter specific pests
Plants to Keep Apart
Allelopathy: Some plants don't play well together
- Black walnut trees inhibit tomatoes and peppers
- Fennel should be isolated - it inhibits most vegetables
- Avoid planting beans near onions and garlic
Creating Your Companion Plan
Start small with proven combinations, then experiment as you learn your garden's unique ecosystem. Keep detailed notes about what works in your specific conditions.
Remember: companion planting is part art, part science, and always an adventure!
