Lace bugs and rhodies

Asked June 6, 2020, 8:27 PM EDT

  • Is it okay to just remove the old leaves damaged by last year's lace bug infestation leaving the new growth only? I sprayed with neem oil about a week ago and am finding a few adult lace bugs under most of the old leaves. They have not moved on to the this year's growth yet.

If you remove the damaged leaves, ALL of the older ones will be gone. Yes, the new growth looks fine now, but it, too, will be damaged before long.

Instead, keep a watch on the undersides of the leaves for the new hatch of youngsters. They're black, about an eighth-inch, and slow moving. Blast them off the undersides with a harsh water blast from the hose.
