Establishment & Care
tomato
Solanum lycopersicum
Nasturtium acts as a trap crop for aphids and repels whiteflies, reducing pest pressure on nearby tomato plants. The pungent volatile compounds deter thrips and spider mites.
Rosemary
Salvia rosmarinus
Rosemary's volatile oils (camphor, borneol) are reported to repel bean beetles and cabbage loopers; nasturtium also repels these pests, creating a complementary deterrent layer.
cabbage, broccoli, and allies
Brassica oleracea
Nasturtium acts as a trap crop for aphids, drawing them away from brassicas. It also attracts beneficial predatory insects that consume brassica pests.
Bronze Fennel
Foeniculum vulgare
Fennel is allelopathic to most companion plants; its root exudates inhibit germination and growth of Tropaeolum and many other species. Fennel is generally best grown in isolation.
