Whispy Wonders: Propagating Mexican Feather Grass (Sporobolus tenuissimus) for a Dreamy Landscape

Mexican Feather Grass (Sporobolus tenuissimus), with its airy plumes and graceful movement, has become a beloved staple in gardens across a range of climates. This elegant grass adds texture, movement, and a touch of whimsy to any landscape.

Division: Sharing is Caring for Mature Clumps

Dividing established clumps is the most common and efficient method for propagating Mexican Feather Grass. It’s best done in early spring just as new growth emerges or in fall when the weather cools down. Here’s how:

  1. Prep the Clump: Water the mother plant thoroughly a day or two before dividing to minimize stress.
  2. Digging Up: Carefully dig around the clump, ensuring you dig a wide enough circle to avoid damaging the roots.
  3. Division Time: Gently lift the clump and use a sharp, clean knife or spade to divide it into smaller sections. Aim for sections with a good amount of healthy roots.
