The small leaves are glossy green and pest-resistant. This tough tree is extremely drought-tolerant. It's a dependable, fast-growing shade tree. The fall color of trees' foliage greatly livens our landscapes. The grayish, stifled look of leaves infested with spider mites is a result of their feeding on plant juices.
Spider mites thrive in hot, dry weather.
For mild infestations, hose the foliage to wash off the mites. For severe problems, spray with an approved chemical by label directions. Drought-stressed plants have less water in their plant tissues. The chemicals that enter the leaves will be more concentrated and may burn the leaves. Pest control is easier and safer while plants are outside for the summer than after you bring them in this fall.
