Companion planting basics
- Good companions can deter pests, improve pollination, or make efficient use of light and root depth
- Bad companions typically compete for the same nutrients, attract shared pests, or release growth-inhibiting compounds
- Tomatoes are one of the most companion-sensitive crops in a home garden — basil and carrots are classic allies; brassicas and fennel are classic conflicts
