If you are looking for a large and impressive shade tree that resembles the American Elm in stature–look no further! Japanese Zelkova has an appealing vase shaped form with a rounded crown. Green leaves in summer give way to an impressive array of autumn colors ranging from yellow to copper to red. It is highly adapted to our alkaline soils and winds, and prefers frequent irrigation like that found in bluegrass lawns. Another important aspect is it has very few insect or disease issues including Dutch Elm Disease. Native to eastern China, Japan and Korea.
Throughout this site, the following are used as guidelines for watering established plants:
These truly xeric plants can live with our 12 inches of natural annual precipitation and only need a winter watering during a multi-year drought, but they will thrive with a monthly watering. Overwatering will kill some of these. These plants are adapted to intermittent deep
watering with soil drying to a depth of a few inches between waterings. Watering frequency may be every couple of weeks during the active growing season and maybe only one winter watering for optimal care. These plants need regular watering somewhat like a bluegrass lawn so that
they never dry to depth in the root system during the active growing season, and need occasional winter watering to prevent root dessication and resultant plant
death. About sizes of our plants:
Sizes indicated with a # are roughly the equivalent in gallonage; so a #2 is about a 2 gallon pot size; b&b stands for balled and burlapped.
