Bermudagrass Seeding Rate
Bermudagrass seeding rates from university extension services — new lawns and overseeding, with every figure attributed. Sources on the methodology page.
New lawn
| Context | Rate | Source |
|---|---|---|
| common bermudagrass, hulled seed | 1–2 lbs per 1,000 sq ft | University of Georgia Cooperative Extension, B1533-2 |
| common bermudagrass, unhulled seed | 3–6 lbs per 1,000 sq ft | University of Georgia Cooperative Extension, B1533-2 |
| common/seeded bermudagrass, new lawn | 1–2 lbs per 1,000 sq ft | NC State Extension Gardener Handbook |
| new lawn | 1–2 lbs per 1,000 sq ft | University of Missouri Extension |
A 5,000 sq ft new lawn needs about 5 to 30 lbs of bermudagrass seed at the published rates.
About warm-season grasses
Bermudagrass and zoysiagrass are the two warm-season lawn grasses covered in this research, and extension guidance for both splits by seed type and cultivar rather than by state. Common bermudagrass grown from hulled seed needs a light seeding rate, a figure University of Georgia Cooperative Extension, NC State Extension, and University of Missouri Extension report within a consistent range of each other. Unhulled bermudagrass seed still carries its seed coat, germinates slower, and needs a much heavier rate than hulled seed, per University of Georgia Cooperative Extension. Improved bermudagrass cultivars bred for finer texture and color, such as Coastal and Tifton types, produce few viable seeds and get planted from sprigs or rhizomes instead of seed. Anyone buying bermudagrass seed should confirm which type is in the bag, since hulled and unhulled seed call for different rates and hybrid cultivars are not sold as seed at all.
Zoysiagrass presents the reverse problem: seed exists, but most zoysiagrass lawns still get established from sod, sprigs, or plugs, because most cultivars do not produce seed that germinates reliably. NC State Extension, University of Georgia Cooperative Extension, and University of Missouri Extension each publish seeding rates for zoysiagrass, but those figures apply only to a small number of seed-propagated cultivars, including Zenith and Compadre. Anyone shopping for zoysia seed should confirm the cultivar is one of the few bred for seeding, since a bag labeled only "zoysiagrass" with no cultivar name may not perform as advertised. Warm-season grasses split their seeding guidance by seed type and cultivar more than by climate zone, the opposite pattern from cool-season grasses, where geography drives most of the rate differences extension services report.
Cool-season grasses show roughly 20-40% rate variation between neighboring states/regions, reflecting climate and pure-stand-vs-blend context. Warm-season grasses split more by seed type (hulled vs. unhulled) and cultivar (seeded vs. vegetative) than by geography. Ranges below are honest regional spread, not error.
Common questions
How much for 1,000 sq ft?
1–6 lbs per 1,000 sq ft for a new lawn, per the sources above. Overseeding takes less.
Why do the sources disagree?
Regional climate and pure-stand versus blend context. We show each source's figure with attribution instead of averaging them.
Rates are extension-published starting points. Your state extension service's lawn calendar beats any national table for timing.
