So I've struggled with a spider mite problem in my potted figs for over a year and a half. Apartment dweller in Ontario, and had tried multiple applications of End All and other such sprays from various nurseries. Works for a few weeks, and then they're back. Tried frequent misting, homemade olive oil and soap sprays, and still no luck. Then in desperation late this winter, I decided to try a 'nuclear' option. Had some flaxseed oil and figured, if it's a dilute oil and soap emulsion that's basically killing the mites, why not COMPLETELY cover the plant in oil, then wash it off? It's dying slowly anyways, and I couldn't stand the smell of End-All inside anymore. So I covered the soil with duct tape to prevent the oil and water from getting into the soil. Then I drenched the leaves, bark, and everything with the flaxseed oil, and promptly washed it off with bar soap, lathering the tree leaves and bark, and finally giving it a good rinse with water. Did it damage the leaves? Absolutely. But did new healthy leaves grow back? You betcha. And it's been several months now, and still no evidence of any mites. Fingers crossed, but I thought I'd share my experience in case it helps anyone else. Flaxseed just happened to be what I had at the time. Not sure that the type of oil matters... anyone else try something this crazy?
