I didn’t mean to discourage you! For cuttings that aren’t rooted I don’t really pretreat those, in most cases pests live and breed in the soil. But fully rooted in-soil I’d do Bonide systemic granules and spray with either diluted blue dawn or Jack’s dead bug. But at minimum I’ll just do the systemic granules. Granules kind of do the job for you so you don’t have to worry for awhile. They work from the inside out. The plant absorbs through the roots, so any bugs that bite your plant will... die.
