In greenhouse I use the Natria Insect, Disease, and Mite Control product. Since I have bromeliads that will get sprayed, following the Natria, I will flush out the "urns" with plain water. I don't know whether this product would do any harm but I don't take the chance that it will. The product has never harmed my other plants as far as I know, but I only use it in the fall.
