Tree

Colorado Spruce (Picea pungens)

Symptoms
Symptoms of SNEED are yellowing and eventual browning of older needles. Affected branches may be scattered through the canopy. Frequently, by autumn, all of the needles on the affected branches fall off except the newest needles on the tips of the branches. Eventually the canopy of the tree thins, sometimes leaving bare branches.
