Lime Application for Zoysia Grass: Test First, Then Apply

All lawn grasses, including zoysia, perform best when soil pH is in the optimal range (typically 6.0–6.5). If the soil is too acidic, fertilizer nutrients become unavailable. Don't guess—get a soil test through your local Extension office or a service like the University of Georgia's soil testing lab.

Lime takes several months to fully react in the soil, so applying it a week early or late makes no practical difference. Even centipedegrass, which tolerates lower pH, benefits from proper liming. A soil test tells you exactly how much to apply.
