Junipers are very susceptible to a disease known as Phomopsis blight, juniper twig blight or juniper tip blight. This disease is most severe on juniper, red cedar and horticultural varieties of these plants. It also occurs on arborvitae (Thuja or Platycladus), cypress (Cupressus), Douglas fir (Pseudotsuga), fir (Abies), hemlock (Tsuga), larch (Larix), redwood (Sequoia), white cedar (Chamaecyparis) and yew (Taxus). Phomopsis blight can be a real problem in nurseries or where plants are growing close together.
