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.

Boulder raspberry is a native shrub grown for its large white flowers. Naturally occuring in the mountains and foothills along Colorado's Front Range, it has an arching, vase-shaped growth habit with thornless branches.
In May and June, it produces large white single flowers. Later, small raspberry-like fruit appear, but are grainy and inedible. Birds like to eat the fruit.
Boulder raspberry has large, beautiful white flowers in early summer. The plant is not that noticeable when out of flower. It produces more flowers when older canes are cut out.
Prune out one-third of older stems in late winter to encourage more flowers.
