SolanaceaeCan you plant chives and tomatoes together?
Yes. Chives and tomatoes grow well together. Tomatoes had less disease next to chives in a field trial, and chives kept pests off tomatoes in a greenhouse or pot trial. That rests on two studies, so treat it as a lead, not a rule.
Why chives and tomatoes work together
Less disease. In a field trial, tomatoes had less disease next to chives.
Intercropping with aromatic plants enhances tomato productivity and disease resilience through elevating soil nutrients and enzyme activities. (Yu Y · 2026 · Pest management science)Fewer pests. In a greenhouse or pot trial, chives kept pests off tomatoes.
Garden charts recommend it. 2 garden chart entries recommend growing them together. None of them cites a source. Charts pass on gardening tradition; they are not tests.
