Can you put potash on your zoysia grass?

Yes, you can apply potash (potassium) to zoysia grass, as it is beneficial for promoting root health, drought resistance, and overall vigor. It's best to conduct a soil test first to determine the existing nutrient levels and to ensure you're applying the appropriate amount. Typically, potash can be applied in the spring or early summer when the grass is actively growing. Be sure to follow the recommended application rates to avoid over-fertilization.
