Dormant Lawn in Memphis, Tan Grass vs Dead Weeds

If your lawn has turned tan, beige, or straw brown, that is usually normal winter dormancy for warm season grasses like bermudagrass and zoysia here in West Tennessee. Dormant grass is simply resting. It is not actively growing, but it is not dead. If you are wondering what a dormant lawn Memphis winters create should look like, the color change is usually normal for warm season grass.

What confuses many homeowners is when a lawn looks tan in some areas and darker or thinner in others. That contrast matters.

In the side by side photo, the left lawn shows a uniform tan color. This is classic healthy dormancy. The turf still looks tight and woven together, just without green color.

The right lawn tells a different story. The darker, thinner, patchy areas are typically dead warm season weeds left over from last year, not dying grass.

When those weeds die off in winter, they leave behind dark brown to nearly black stems, a thin and matted texture, and visible gaps where weeds once crowded out turf.

A simple rule of thumb helps. Dormant grass looks like tan carpet. Dead weeds look dark, thin, and patchy.

Why does this matter? Those thin areas allow sunlight to reach bare soil,

which creates the perfect conditions for spring weed germination.

That is why pre emergent timing is so important. By the time weeds are visible in spring, they have already germinated.

In West Tennessee, effective weed prevention starts before spring fully arrives, not after. Dormancy is normal. Dark thin patches are the warning sign. Getting ahead of weeds starts now, not later.
