Understanding Rhizomatous, Stoloniferous, and Bunch-Type Grasses

Different grasses spread in different ways. Understanding these habits helps you pick the right mix and set realistic expectations for how quickly your lawn will fill in and repair damage.

Growth Habits Explained

  • Rhizomatous (Kentucky bluegrass): Underground stems that send up new shoots. Excellent self-repair and filling power.
  • Stoloniferous (some fescues, bentgrass): Above-ground runners. Good at spreading but can be thatch producers.
  • Bunch-type (tall fescue, perennial ryegrass): Grow in clumps, no spreading stems. Rely on tillering; don’t fill bare spots on their own.
Why it matters: A pure tall fescue lawn will need overseeding to repair wear. A KBG-dominant lawn will knit itself back together faster.
