Why 'Emerald' Zoysia Sod Can Look Different

Not all sod sold as 'Emerald' zoysia is genetically identical. UGA turf specialist Clint Waltz analyzed 16 samples sold under this name and found significant DNA variability and differences in spring green-up. Sod farms may believe their stock is true 'Emerald' based on appearance, but differences often only become obvious during seasonal transitions.

If your new patch looks darker and grows slower, it's likely a different variant. Blending may improve over time, but perfect uniformity is not guaranteed.
