Answer: Yews are generally problem free although spider mites may colonize within them. You can discourage these pests by hosing the foliage off a few times during the summer months. Spider mites like dry, dusty places. Hosing off your yews will keep these pests at bay. Check your plant for webbing and hold a sheet of white paper in towards the center of the plant, then shake the branches. Spider mites look like little specks of pepper, but they move!
Best wishes with your landscape!
