Creeping Mazus problems — and how to fix them
Creeping Mazus (Mazus reptans) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slugs and snails
The main pest of Mazus reptans. Slugs graze young growth and flower buds, particularly in moist conditions that also suit the plant. Apply iron-phosphate slug pellets or place grit barriers. Checking at night and hand-picking is effective for small plantings.
Drying out / browning in heat
Unlike drought-tolerant ground covers, Mazus reptans browns rapidly in dry, hot weather. Maintain consistent soil moisture, mulch the root zone lightly with leaf mould, and provide afternoon shade in warmer zones.
Winter dieback in cold zones
In USDA zone 5, the mat may die back partially or fully in harsh winters. Protect with a light covering of dry mulch or evergreen branches over winter; the crown usually re-sprouts reliably in spring.
