Companion Planting Guide
Companion planting is best when you keep it simple: pair plants to help with pests, pollination, or space.
Easy companion planting combos
- tomatoes + basil
- tomatoes + marigolds
- carrots + onions
- cucumbers + nasturtiums
- lettuce + taller plants for light shade
What to avoid (common conflicts)
- don’t crowd heavy feeders together (they compete)
- avoid pairing plants that need totally different watering
