Sand Bluestem

Andropogon hallii

Sand Bluestem is an evergreen, perennial grass native to North America. It is one of the dominant plant species found in sandy prairies and can often reach up to 4 ft in height. Although long-lived, it matures in late summer and produces tufts of light-brown, spike-like flowers that develop into slender, bead-like grains at the end of the stem. Its foliage is a bluish-green and usually grows in clusters, with long, thin leaves taking the shape of a blue-green fan. Its grassy texture and unique color contribute to its popularity as a landscaping ornamental grass and make it a valuable wildlife habitat for birds and small mammals.

watering

Sand bluestem typically prefers drier soils, and can tolerate drought. Depending on soil type and weather conditions, water weekly to every 2 weeks as needed. In general, 1-2 inches of water per week during the growing season should be sufficient. Avoid over watering, as this can lead to root rot or fungal diseases. During hot, dry weather, water more frequently. If the soil is sandy or heavy clay, you may need to water more frequently. If the plant wilts or shows signs of drought stress (yellowing leaves), you may need to increase water frequency.

sunlight

Sand Bluestem requires 6 to 8 hours of sunlight per day in order to thrive. It prefers direct sunlight, although it may tolerate some shade. The best time of day for Sand Bluestem to receive the most sunlight is between 10am and 4pm.

pruning

Sand Bluestem should be pruned annually in late winter or early spring, before the start of its active growing season. Prune off any dead, damaged, or broken stems, as well as any stems that may be growing too close together. Pruning should involve removing the top ¼ to ⅓ of the stems, leaving the thicker, branchier stems at the base of the plant intact. This will promote bushier growth and a more attractive appearance.
