I had been repotting a number of succulents I propagated back in the Fall. When I started pulling some of the cuttings out I noticed that one by one, they all had a root aphid or similar infestation. It’s just about time to take all of my cuttings and specimen succulents outside with the remainder of my outdoor trees. What makes this even harder is I live in DC so my backyard is very compact. Segregating the infected is not necessarily an option.
Back in 2015 you had a great article where you tested about 6 different methods of treating root infestations. Any chance that data has been collected and shows which trees benefited the best from each approach?
