Companion Planting for a Baby Food Garden: What to Grow Together

Some crops grow better next to each other. Some actively hurt each other. For a baby food garden where space and yield both matter, knowing the basics will save you from planting tomatoes next to broccoli, or fennel next to anything.
Good companions
Tomatoes + basil
The classic pairing. Basil may repel aphids and whiteflies from tomato plants. They also taste great together, which matters when you are making pasta sauce for the family and soft tomato wedges for the baby.
Carrots + onions
Onions repel carrot fly. Carrots repel onion fly. Growing them in adjacent rows is a natural pest management strategy.
Beans + corn + squash
The Three Sisters. Corn provides a natural trellis for beans. Beans fix nitrogen in the soil. Squash shades the ground and suppresses weeds. All three are excellent baby foods.
Lettuce + tall crops
Lettuce bolts in heat. Planting it in the shade of taller crops like tomatoes or corn extends the harvest window.
Bad companions
Fennel + almost everything
Fennel releases chemicals that inhibit the growth of most vegetables. Grow it in its own container or at the far edge of the garden.
Tomatoes + brassicas (broccoli, cabbage, cauliflower)
Both are heavy feeders that compete for the same nutrients. Give them separate beds.
Beans + onions/garlic
Alliums (onions, garlic, leeks) inhibit the growth of beans and peas.
Layout tips for a baby food garden
- Group heavy feeders together (tomatoes, squash, corn) and light feeders together (beans, peas, root vegetables).
- Rotate crop families each year to prevent soil depletion and disease buildup.
- Plant herbs (basil, parsley, mint) at the edges where they can attract beneficial insects without competing for space.
