Planting & Care

Where to Plant

  • Sunlight: Big Bluestem requires at least 6 to 8 hours of full, direct sun daily to maintain its structural integrity. While it can survive in partial shade, the stems will likely flop over and the iconic blue-green and purple hues will be much less vibrant.
  • Soil: This grass is incredibly adaptable and thrives in anything from heavy clay to rocky slopes. If you have extremely sandy soil, mixing in a bit of compost helps hold moisture while the deep roots establish themselves to reach the water table.

Watering Requirements

During the first growing season, water your Big Bluestem twice a week to ensure the root system reaches deep into the soil profile. Once established, this native grass is exceptionally drought tolerant and typically relies on natural rainfall alone. If you overwater a mature plant or provide inconsistent irrigation, the grass may grow too tall and weak, causing the center to splay open.

Pruning Tips

Since this grass provides excellent winter interest and shelter for birds, wait until late winter or very early spring to cut it back. Use sharp shears to trim the entire clump down to about 3 or 4 inches above the ground before the new green shoots emerge from the base. This "haircut" clears out the old growth so the plant can focus all its energy on the fresh, vigorous stems of the new season.

Fertilizer Needs

Big Bluestem actually prefers lean soil, so a single application of a balanced, slow release fertilizer in early spring is all it needs. Avoid using high nitrogen fertilizers late in the summer because this encourages succulent growth that won't harden off properly before the first frost. Excessive feeding can also lead to "lodging," where the plant becomes top heavy and falls over under its own weight.

Frequently Asked Questions

Is big bluestem grass invasive?

  • Big Bluestem is not invasive and is actually a well-behaved native grass that stays in clumps rather than spreading aggressively. This prairie native adapts well to zones 4-10 and maintains a tidy 2-3 foot width even at full maturity. Plant it confidently in borders or naturalized areas where you want reliable, architectural structure.

What does prairie grass look like?

  • Big Bluestem prairie grass grows 4-6 feet tall with a columnar form, displaying blue-green summer foliage that transforms to reddish-bronze with lavender tones in fall. The distinctive forked seed heads appear July through October, earning it the nickname "Turkey Foot Grass." Plant in full sun for best color development, available at naturehills.com.

What planting zones is Big Bluestem Grass hardy in?

  • Big Bluestem Grass thrives in USDA hardiness zones 4 through 10, making it adaptable across most of the United States. This native prairie grass tolerates a wide range of climates from cold northern regions to hot southern areas. Plant it in full sun for best results.

How often should I water Big Bluestem Grass after planting and once established?

  • Big Bluestem is drought-tolerant once established and rarely needs supplemental watering. Water newly planted grass regularly for the first growing season to help roots develop. Once established, this native prairie grass thrives on natural rainfall alone in zones 4-10.

Should Big Bluestem Grass be cut back in fall or spring?

  • Cut Big Bluestem in late winter or early spring before new growth begins. The seed heads provide beautiful winter interest and wildlife value through the cold months. Cut stems back to 4-6 inches above ground in February or March for best results.
