They are in fact and they’re showing up earlier than normal, as many things are this spring. Mites, not might, that is-on junipers, evergreens, Pyracantha ,even vegetable plants and winter annuals. From a distance it might appear that your plant was just caught in a dust storm. A dusty brown to grayish look covering some if not all the plant. Upon closer inspection you might see fine webbing (if problem is pretty advanced) but hardly ever can see the pest with the naked eye. The best way to see them without magnification is to tap or shake a limb of leaf of the affected plant onto a piece of light colored paper and wait for the tiny specs to start moving about. Mites are fast breeders and spread quickly- they suck the plant out of chlorophyll which also why the plant might have a funny color to it. Keeping plants clean and free of dust is one way to minimize mite populations. Depending on what type of plants they are on, treatments can vary. One of our favorites is Spinosad. It is safe to use on any ornamental and on fruits and vegetables. If you’re not sure what might be wrong with your plant, if anything, please bring in a sample and we’ll gladly make a recommendation for you!
