Garden allies

Beneficial predators that hunt this plant's pests — grow their favourite flowers nearby to recruit them. companion plant

  • Ladybird (lady beetle) Coccinellidae

    The gardener’s favorite ally: adults and their alligator-shaped larvae each eat thousands of aphids, plus scale, mealybugs, and other soft-bodied sap-suckers. Grow flat, open flowers for the adults and never spray a colony that ladybird larvae are already working.

  • Hoverfly Syrphidae

    Bee-mimicking flies whose legless larvae graze aphid colonies clean while the adults pollinate. A ribbon of shallow, nectar-rich flowers kept in bloom all season recruits wave after wave of them.
