This large, relatively fast growing asiatic elm has resistance to Dutch elm disease elm yellows (phloem necrosis), but is susceptible to elm leaf beetle. The urban tolerance of this plant is well known. The plant is considered unnatractive by many due to it's ragged habit and loss of branches from breakage. It also has escape potential and is becoming established as a pioneer invader species in many areas, particularly disturbed sites. Wound response of the trees is quite excellent, and it tolerates a wide range of drainage conditions from wet to dry. While it is unlikely that urban foresters will rush out to plant Siberian elms, there may be a place for these trees in exceptionally difficult urban situations, and as a member of the elm family will increase biodiversity in many areas.
The Siberian elms pictured below are planted in a grassy median strip near The Ohio State University, in Columbus, Ohio. The median is slightly depressed, poorly drained and there is no curb. Pedestrian traffic is infrequent. Salt accumulates in the area during the winter, cars tend to hit the trees on a frequent basis, and soil compaction is also a problem. Many other trees would fail in this situation, however the siberian elms have proven up to the task and continue to recover from stress and vehicle damage, providing shade where otherwise there would be none. In an exceptionally difficult situation like this, the Siberian elm may be a good option.
