Hi there, I have some otherwise very healthy Resilience lilly pillies that are recently having a problem that started with one plant, but now all 7 seem to have it. The new growth is small and completely curling in on itself. No discolouration anywhere. I can see no mealy bugs, and I can't find a solution anywhere online because every website wants to tell me that the problem is psyllids, which is not what this looks like (it is also a psyllid resistant cultivar). I really need these trees to keep growing strong as they are a privacy screen, any advice would be very much appreciated!
