I have a fairly large rhodo in the Cowichan Valley of Vancouver Island which has recently become infested with spider mites. I am wondering what would be the best, eco friendly, way to get rid of them - a spray or whatever. A small hand-held trigger bottle will be too small, so I need something that would work in a hose-end sprayer. Thanks!
Use some garden sulphur mixed in water and sprayed on a cloudy day......it is a miticide and can be used as a fungicide as well. Ian
