I have a cattleya that I think has spider mites. I have tried spraying it with soapy water but the marks on the leaves are still growing. I am considering trying Bayer rose and flower the granular kind. Will this work or do I need a different Bayer product.
The problem with the granular version of Bayer is that it takes weeks to get to the leaves. I have had success with the Bayer Mite and Disease Control liquid, diluted and applied according to the directions. I would tend to keep it off the flowers, although I have not seen damage from contact yet...... It should be available at Home Depot or one or your local garden box stores here in the US.
