Japanese Boxwoods - Knowledgebase Question

Hi, my mature boxwood shrubs have been yellowing and look to be dying. I thought it was the 100 degree heat and sun but now I suspect insects. Only a few are still green but they are now showing signs of yellowing. Any idea as to what is wrong? Thanks!

Yellowing foliage almost always indicates water stress - usually too much. Poorly draining soils can actually suffocate roots. Other things to look for are spidermite insects. You'll see webbing where the leaves meet the stems. Usually the leaves are stippled green when spidermites are feeding. Hope this information helps you determine just what's going on with your boxwoods.
