Zoysia Fertilizer & NPK Guide
Zoysia needs 2-3 lbs of nitrogen per 1,000 sq ft per year — significantly less than bermuda's 3-5 lbs. Recommended NPK ratio is 4-1-2 (e.g., 16-4-8). Apply PGF Complete at the LOW end of the bag rate. First application when zoysia is fully green and actively growing (soil temps 65°F+), NOT at first green-up. Space applications every 6-8 weeks during the growing season — no more than 3 granular feedings total. Over-fertilizing zoysia accelerates thatch buildup, its biggest maintenance problem. Stop all granular nitrogen by early September to allow proper hardening before dormancy.
Frequently Asked Questions
How much fertilizer does zoysia need?
Apply 2-3 lbs of nitrogen per 1,000 sq ft per year, split across 2-3 applications during the growing season. This is about 40% less than bermuda requires.
What NPK ratio should I use on zoysia?
Use a 4-1-2 ratio like 16-4-8 (PGF Complete). Apply at a lighter rate than bermuda — 0.5 lbs N per 1,000 sq ft per application is plenty.
When should I fertilize zoysia?
First application after full green-up in late spring, a second in mid-summer, and optionally a light third in early fall. Never fertilize dormant zoysia.
