Red Dye
From our facebook page, comes a buggy question.
I have this pot with diff cacti in it. I notice this white stuff since mid summer. Do you know what’s the white stuff growing on them? and why?
It has been spreading already. Thank you for your help. Kenya
Kenya,
You’ve got Cochineal, a pest that will eat your cactus, but on the good side it is the original source for red dye.
I recommend spraying with neem oil, and cleaning the bugs off with alcohol and a soft… paintbrush.
