Pests & problems

• Mealybugs White cottony sap-suckers that gather in leaf axils and along stems, mostly on houseplants and under glass. Dab colonies with a cotton swab dipped in soapy water and isolate affected plants.
• Scale insects Immobile brown or white bumps fixed to stems and leaf undersides, sucking sap and weakening growth. Wipe off with a damp cloth or dab with horticultural soap; watch for the sooty mold that follows.
• Spider mites Red spider mite
• Root & crown rot Root rot from overwatering
• Sooty mold A black film growing on the honeydew left by aphids, scale, or whitefly above. Deal with the sap-sucking pest and sponge the leaves clean.

Garden allies

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

• Ladybird (lady beetle) Coccinellidae
  Hunts Scale insectsMealybugsSpider mites

  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.

• Green lacewing Chrysoperla carnea
  Hunts MealybugsSpider mites

  Its bristly larvae — "aphid lions" — impale aphids, mealybugs, thrips, and mite colonies, eating hundreds a week. Adults feed on nectar and pollen from small open flowers and overwinter in hollow stems left standing.

• Hoverfly Syrphidae
  Hunts Scale insectsMealybugs

  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.

• Big-eyed bug Geocoris spp.
  Hunts Spider mites

  A stubby 3 mm bug with enormous wrap-around eyes, working the soil surface and the low foliage for aphids, mites, thrips and insect eggs. It is the main natural check on chinch bugs in a lawn and it is killed outright by insecticide.

• Minute pirate bug Orius spp.
  Hunts Spider mites

  A pinhead-sized true bug that is the best natural check on thrips, and happily spears aphids, mites, and insect eggs too. It needs pollen when prey is scarce, so keep something flowering nearby.

• Predatory mites Phytoseiulus & Amblyseius
  Hunts Spider mites

  Fast orange mites that hunt spider mites egg-by-egg, and cousins that clear thrips and fungus-gnat larvae. Sold as a biological control for greenhouses; outdoors they follow humidity — mist and mulch, don’t dust with sulfur.

• Rove beetle Staphylinidae
  Hunts Spider mites

  Slim, quick beetles with short wing cases that hunt in soil and litter, taking root-fly eggs and larvae, fungus-gnat larvae, and mites. Mulch and undisturbed ground keep them resident year-round.
