Gardeners' Notes:


On Dec 10, 2008, realbirdlady from Austin, TX (Zone 8b) wrote:

Very well-adapted to Central Texas. They tend to grow naturally alongside ashe juniper ("cedar"), which is where their name comes from. They're good wildlife habitat, a larval food for a couple of kinds of butterflies, and a good nesting site for birds.

Cedar elm is also generally good as a yard shade tree. They grow fairly quickly, don't result in such deep shade as to leave bare dirt underneath, and have small enough leaves to simple allow to compost in place. They do need some simple pruning, especially when small, to form a strong structure and avoid limb breakage problems down the road. Some people are very allergic to the pollen however.

Very common in South Bexar Country. When clearing brushy land, I tend to leave the cedar elms and mesquites and destroying all the hackberrys. When naturally occuring with hackberrys, the cedar elms won't grow to full height - once allowed the sun, they will spread out and flourish.
