Companions

Keep apart: the tomato family (nightshades). Cabbage-family crops and tomatoes compete and can stunt each other.

Keep apart: Horseradish. Horseradish spreads aggressively. Give it its own spot.

Keep apart: Strawberry (June-bearing), Strawberry (everbearing). Cabbage-family crops can stunt strawberries.

Keep apart: Mint. Mint spreads aggressively into neighbors. Keep it in a pot.

Keep apart: Fennel (bulb). Fennel slows the growth of most garden plants. Grow it on its own.

Keep apart: Sunchoke (Jerusalem artichoke). Sunchokes spread aggressively and shade neighbors.

Tips

  • Cover crops before the bugs find them. Put row cover or insect netting over cabbage, kale, and other greens the day you plant. It keeps out cabbage moths and flea beetles with no spraying at all.
  • Move crop families every year. Pests and diseases build up in the soil. Don't plant tomatoes where tomatoes, peppers, potatoes, or eggplant grew last year: they're one family and share the same problems.
