What to do about cochineal on cacti and prickly pear plants
Our “gogga” of the month for July, cochineal, are sap-sucking insects that feed only on cacti and prickly pear plants. Feeding causes discolouration of plants, swelling around the area which has been fed on
What does this mean for me/my plants?
Use a combined contact and stomach insecticide, together with a wetting agent – prickly pear bushes have a wax type leaf and whatever you apply will just run off. Top tip: if there are no water restrictions in your area, try and loosen the cochineal with a hose pipe and high pressure nozzle prior to spraying, as the insect burrows deeply into the holes. Visit your local GCA Garden Centre for advice on how to treat cochineal infested plants!
