mealybugs on Echinocereus Fendleri

Quick answer

If your Echinocereus Fendleri has mealybugs, the most likely cause is: Mealybugs are listed as the most important pests of cacti including Echinocereus fendleri; the white woolly female lays up to 500 eggs three times a year, with each batch hatching in roughly 10 days, and a soil-dwelling root-mealy form attacks the roots before any sign shows above the surface, so a sickly plant is the first hint that root mealies are present.

Start here:

  1. 1. Shake off the old soil and dip the entire root system of an infested Echinocereus fendleri in methylated spirit, then let the roots dry before re-potting into fresh, sterile cactus compost.
  2. 2. Spray the stems, crown and any exposed roots thoroughly with a relatively environmentally benign plant spray such as neem oil or insecticidal soap, repeating every 7 to 10 days until no fresh white woolly masses appear.
