Catnip repels flea beetles that pockmark beet leaves; different root zones mean minimal competition.
Catnip's strong mint-family scent repels cabbage moths, flea beetles, and aphids from brassicas; attracts parasitic wasps.
🤝 Collards
Catnip's strong scent masks collards from harlequin bugs and cabbage loopers; both thrive in similar growing conditions.
Attracts beneficial wasps and predatory insects that parasitize potato pests; may provide general aromatic camouflage. Note: No peer-reviewed evidence supports catnip as a Colorado potato beetle deterrent.
Catnip repels aphids from roses; its gray-green foliage and lavender flowers complement rose beds aesthetically.
Catnip deters squash bugs and cucumber beetles; flowers attract bees essential for squash pollination.
Catnip deters aphids and whiteflies from tomatoes; attracts pollinators that improve tomato fruit set.

⚠️ Keep Apart (4)

Both are mint-family spreaders that compete aggressively for space; their combined growth creates an impenetrable, over-crowded mess.
Both are aggressive spreaders in the mint family; planting together creates an uncontrollable tangle where neither thrives.
Catnip's spreading habit can overrun low-growing parsley; different water needs (catnip prefers drier soil).
Catnip's bushy growth shades out low strawberry plants; cats attracted to catnip may trample strawberry beds.

📝 Growing Notes

Contains nepetalactone , attracts and intoxicates ~70% of cats (genetic trait). Also repels mosquitoes, cockroaches, and termites (research shows nepetalactone is 10x more effective than DEET for mosquitoes). Excellent bee plant , flowers heavily and for extended periods. Catmint (Nepeta × faassenii) is a showier ornamental cousin with less medicinal value. Self-seeds readily; deadhead to control spread. Square stems, opposite leaves typical of mint family. Cats may roll on and destroy plants , protect with wire cage or plant decoy patches.
