Question From: VIRGINIA
Q: Live in Winchester, VA and all limbs on 2 year old crepe myrtal (variety listed as ok for zone 6) turned black during severe cold snap we had for about a month this winter. Does the blackened bark mean all upper branches dead or should I wait until June to see if life comes back?
Jim, If it were in warmer weather I'd say it was sooty mold, which will not kill the tree. I'd be patient and see what happens. Best And Happy Yardening, Nancy
