Tomato & basilPair
Tomatoes · Basil
Classic neighbors: basil likes similar warm soil and steady water; flowers draw small beneficials when you let a few bolt late.
Borage & tomatoesPair
Borage · Tomatoes
Borage flowers for bees; young leaves are edible (hairy texture). Self-seeds freely—place where volunteers are welcome.
Chives & carrotsPair
Chives · Carrots
Low allium scent along a carrot row is easy to tuck in; perennial chives need a permanent edge so you do not disturb carrot roots yearly.
