Zoysia grass seeding rate

How much zoysia grass seed you need

Zoysia grass seeds at about 2 lbs per 1,000 sq ft for a new lawn and 1 lbs per 1,000 sq ft to overseed an existing one — so a 5,000 sq ft lawn takes roughly 10 lbs new or 5 lbs overseeding. That rate is the single biggest driver of how much seed you buy; the rest is your actual square footage.

The rate is set by seed size and how the plant fills in. Zoysia grass is a warm-season grass, and it spreads to fill gaps, so a lighter rate goes a long way. Over-seeding past the recommended rate just wastes seed and forces seedlings to compete.

Timing matters as much as quantity: sow zoysia grass in late spring to early summer when soil is 65–70°F. Germination and coverage also depend on seed quality (check the tag's purity and germination %), seed-to-soil contact, and steady moisture for the first few weeks — buy about 10% extra for bare or high-traffic spots.

Zoysia grass seeding tips

• Sow in late spring once soil is reliably warm — seeding too early in cold soil rots the seed.
• Apply zoysia grass at 2 lb/1,000 sq ft for a new lawn (1 lb to overseed) — spread half in each direction for even coverage.
• Keep the top inch of soil consistently moist until germination — light, frequent watering beats one deep soak.
• Hold off on weed-and-feed until new grass has been mowed 2–3 times; pre-emergent herbicides also stop grass seed from sprouting.
