Species Rock Wormwood

Rock Wormwood

Artemisia woodii

Rock Wormwood (Artemisia woodii) is a low-growing, mat forming perennial shrub native to western North America. It is green-gray in colour and grows up to 2 inches tall. It forms dense, spreading clusters of narrow, needle-like leaves with tiny white flowers. The plant produces a large number of seeds that can remain dormant for many years, leading to regrowth even in adverse conditions. It is tolerant of drought, poor soil, and burial under debris, but prefers a well-drained site high in calcium and low in nitrogen. Rocks Wormwood can be used in rock garden beds, for erosion control, as a low-growing ground cover, or as an attractive border.

watering

Big Sagebrush species require infrequent watering and can survive brief periods of drought. The ideal amount for this species is 1-2 gallons of water, spread over the entire root zone, once every 3-4 weeks. If temperatures are warm and the plant is actively growing, water may need to be increased to once every 2 weeks. The soil around the plant should be allowed to dry out between waterings to a depth of 3-4 inches. It is important not to overwater as this will lead to root rot.

sunlight

Big Sagebrush (Artemisia tridentata) is a shrub that thrives in arid climates and requires plenty of sunlight to grow. This plant species prefers full sun, or 6 to 8 hours of direct sunlight per day, during its peak growing season between early spring and late summer. During other times of the year, Big Sagebrush may do well with slightly less sunlight, provided that there is some degree of natural sunlight available. It is important to note that Big Sagebrush is a hardy species that can tolerate a variety of sunlight conditions, but it is best to provide direct sunlight during its peak growing season if possible.

pruning

Big Sagebrush (Artemisia tridentata) should be pruned back in early to midsummer once the plant has flowered. If the shrub is being used for a specific shape, annual pruning is recommended. Pruning should involve removing up to 1 third of the oldest branches to keep the plant healthy and compact. Additionally, dead or diseased branches should be removed during this pruning session. For managing the size of large shrubs, reach into the shrub and stagger pruning so that an even distance is maintained between branches. Prune with sharp tools to ensure heath and clean cuts.
