Soil & Planting

Companion Plants

• Cherry Tomatostrong

  Garlic is the strongest Allium fungal suppressant; allicin compounds in soil powerfully inhibit Fusarium, Pythium, and Phytophthora — three main soilborne threats to tomato

• Bird's Eye Chilistrong

  Garlic volatiles (allicin, diallyl disulfide) most effective at repelling spider mites and aphids from chili plants; intercrop 1:4 ratio

• Kalemoderate

  Kale ground cover retains soil moisture around garlic; different pest profiles

• Kailan / Chinese Broccolimoderate

  Kailan ground cover retains moisture around garlic; different pest profiles

Plants to Avoid Nearby

• Long Bean

  Garlic is the most phytotoxic Allium to legume Rhizobium; allicin levels from garlic are 3–5× higher than shallot; keep minimum 80 cm separation from all legumes

• Edamame

  Garlic is strongly antagonistic to soybean/edamame nitrogen fixation; never plant within 80 cm of edamame planting

• Groundnut / Peanut

  Garlic root exudates toxic to legume nitrogen-fixing bacteria

• Garden Pea
