If your blue spruce has needles turning a dull bronze or gray color this month, spider mites are a likely cause, not drought.
These mites thrive in hot, dry late-summer weather and are easy to miss because they're too small to see without shaking a branch over a piece of white paper first.
Left alone, heavy infestations can cause enough needle loss that a spruce never fully recovers its shape. Our plant health care team can confirm mites versus other stress and treat accordingly.
Have you noticed any bronzing or thinning on evergreens around your property this summer?
