Best Time to Fertilize Zoysia Grass
The timing of fertilizer application plays a crucial role in the health and appearance of your zoysia lawn. Fertilize your zoysia grass during its peak growing season to ensure it receives the right nutrients at the right time.
-
Spring (Late March to Early April): The best time to apply fertilizer to your zoysia grass is after the last frost, typically around late March or early April. This is when the grass begins to wake up from dormancy and start growing actively.
-
Summer (June to July): Fertilize again in mid to late summer to keep the grass growing strong during the hottest months. Avoid fertilizing in the early summer to prevent stimulating growth during extreme heat.
-
Fall (September to October): A final round of fertilization before the grass goes dormant will help strengthen the roots for the winter months.
