Use the plant water needs as a guideline. Actual plant water needs will vary for several reasons, including weather conditions, soil type, sun exposure, root depth, wind and elevation. Adjust your watering schedule as needed to meet the plants' needs at your site. Water recent transplants more often than established plants.

Autumn Purple ash is a medium size shade tree grown for the striking purple color of its leaves in fall. It develops a uniform, rounded crown as it matures. Due to the presence of the emerald ash borer in Colorado, tree care professionals are no longer recommending ash trees be planted in Colorado.
There is a beautiful autumn purple ash growing at the Xeriscape Garden. It has a moderate growth rate and a uniform, rounded shape. The fall color is very attractive.
Prune when young to achieve a structurally sound tree. For existing trees, protect them from emerald ash borer once the insect is found within a 50 mile radius. It is currently limited to the Boulder/Denver area.
