Planting & Care

Where to Plant

  • Sunlight: Full sun is essential for this grass to maintain its upright structure and metallic blue color. Provide at least six to eight hours of direct light daily or the stems may flop and lose their narrow, columnar shape.
  • Soil: This plant is famous for its versatility and thrives in almost any soil from heavy clay to dry sand. If you have extremely poor soil, adding a scoop of compost at planting helps, but avoid over-enriching the area as this grass actually prefers lean conditions to stay sturdy.

Watering Requirements

During the first growing season, water your Heavy Metal Switch Grass once or twice a week to help the deep root system get established. Once mature, this native grass is exceptionally drought tolerant and typically only needs supplemental water during extended dry spells. Inconsistent watering or overly wet feet can lead to weak stems, while consistent moderate moisture results in the best height and flower cloud production.

Pruning Tips

Because this grass blooms on new wood, you should cut the entire plant back to about three or four inches above the ground in late winter or very early spring before new green shoots appear. Think of this like a fresh haircut that clears away the old, tan foliage to make room for the vibrant blue growth. Leaving the dried stalks up through winter provides great visual interest and shelter for songbirds, so there is no rush to prune in the fall.

Fertilizer Needs

Apply a light application of a balanced, slow release fertilizer once in early spring as the plant begins to wake up. Avoid using high nitrogen fertilizers late in the summer because they can stimulate soft, lush growth that won't have time to harden off before the first frost. This grass is a light feeder, and over-fertilizing is often the primary reason for a plant "lodging" or falling over in the garden.
