I have a tall (20-25 feet) cedar hedge that is infested with spider mites. Given the height of the trees, I cannot easily spray them with insecticide. As an alternative, I was thinking of blasting away the mites with a power washer. If done on a regular basis, the mites may be reduced in number sufficiently for the trees to survive their attacks. I was thinking of purchasing a 1700psi electric washer for this purpose. Makes sense ?
