The Zelkova is a wide-spreading, vase-shaped tree with beautiful fall colors and attractive toothed leaves. In the fall, trees usually show red, yellow, orange, and green leaves all at one time.
A close relative of the elm, the Zelkova shares its fast growth but not its disease problems. It is suitable for planting in a lawn. Annual pruning when young is necessary to remove competing branches so the tree can develop a few, strong main branches.
Note that any tree grown in a lawn may develop surface roots unless irrigation is properly managed. Tree roots need both air and water in the root zone. Lawns are frequently overwatered, resulting in water-logged soil with no air in the root zone. Check your tree’s root zone to see if it is water-logged or too dry. The best method is to dig a small hole about 12 inches deep and look at the soil: if it is bone dry, there is not enough water; if it is muddy, there is too much water; if it is moist like a cake, it is just right. Alternatively, you can use an inexpensive moisture meter from your nursery or hardware store and look for a “moist” reading.
