Palmer's Indian Mallow problems — and how to fix them
Palmer's Indian Mallow (Abutilon palmeri) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frost dieback
Temperatures in the low -3°C range (mid-20s°F) will kill stems to the ground, but established plants with protected root crowns typically resprout from the base in spring; plant near large rocks to buffer frost.
Root rot in heavy or wet soils
Prolonged soil moisture — especially in winter — quickly leads to fatal root rot; this desert native must be grown in the sharpest possible drainage and never supplementally irrigated in the cool season.
