The bark is grayish pink that becomes grooved as the tree diagram matures . The cedar elm is susceptible to Dutch Elm disease , wetwood , blackspot and anthracnose .

Dutch Elm Disease

Dutch Elm disease has carry off the elm Sir Herbert Beerbohm Tree population . Cedar elms are not as affect as other elm species , but are still in danger . The disease is a make by a fungus that is go around by the elm barque beetle as it tunnels under the bark . The fungus blocks the connective tissue of the tree , depriving the upper branches of water . Symptoms start with leaf curling on the upper branches , according to the USDA Forest Service . Leaves turn yellow , then brown . Another telltale sign is upright streaks in the underbark .
