Monkey Grass (Liriope) Decline in New Orleans: Causes & Fixes

Monkey grass thriving in some spots but yellowing/dying in others points to localized root-zone issues.

Three Likely Culprits

Root eaters: Voles, gophers, or grubs. Dig a declining clump—check roots.
Loose soil: Roots need firm contact. Water settling or foot traffic creates air pockets.
Poor drainage: Liriope likes moisture but rots in standing water. Soggy soil = dead roots.

Pull a yellow plant. Black/mushy roots = rot (drainage). Chewed roots = pests. Loose soil = firm it in.
Replant divisions in amended, well-drained soil.
Top-dress with compost. Water deeply but infrequently.

Liriope is tough. Fix the micro-site, and it recovers fast.
