|What soil amendment will encourage root growth for my zoyzia grass?|
|If you are just now planting zoysia, it does best in a soil with the pH of 6.0-6.5 and getting the soil tested would be the first step. Then you can incorporate lime (if needed) and ferilizer (depending upon your soil test, but usually a complete fertilizer such as a 10-10-10 should be mixed into the soil). Then the area should be leveled and planted. If your zoysia is already installed and growing, you should fertilize with approximately 15 lbs of a complete fertilizer per 1000 sq. ft. of lawn area in the spring. This is the main feeding of your zoysia lawn. For supplemental feedings, you can apply 2-3 lbs of Nitrogen to your Zoysia during the course of the growing season. Space these applications out about 50-60 days apart. The usual ratio of NPK for zoysia is a fertilizer is a 16-4-8. Zoysia is slow to establish, but once it does, it will grow thick and lush and crowd out most weeds.
Best wishes with your lawn.
