How to Plant Bahia Grass
How to plant bahia grass from seed. Argentine variety selection, seeding rate, soil preparation, watering, and germination timeline for new bahia lawns.
Always plant Argentine bahia for home lawns. Pensacola bahia is cheaper but too coarse and open for residential use. Look for 'scarified' seed, which has been mechanically scratched to improve germination. Unscarified bahia seed has a hard coat that slows and reduces germination. Expect to pay $4 to $6 per pound for quality Argentine seed.
Plant when soil temperature is consistently above 65 degrees: late May to early July in zone 8, April to June in zone 9 to 10. Bahia needs a full growing season to establish before winter dormancy. Planting too late (after July) risks thin, immature turf going into its first winter.
Bahia tolerates poor sandy soil but establishes faster in prepared ground. Till the top 2 to 3 inches, remove debris, and grade smooth. Bahia prefers acidic soil (pH 5.5 to 6.5). If your soil test shows pH above 7.0, apply sulfur to lower it. Do not add lime unless pH is below 5.0.
New lawns: 8 to 10 lbs per 1,000 sq ft. Overseeding thin areas: 5 to 7 lbs per 1,000 sq ft. Bahia seed is larger than bermuda or fescue, so the higher rate is needed. Broadcast in two perpendicular passes with a spreader set to half rate. Lightly rake to achieve quarter-inch soil coverage.
Keep the top inch of soil moist for 21 to 28 days. Light watering twice daily (10 minutes per zone) works better than one heavy soaking. After germination, transition to deeper watering every 2 to 3 days for 4 weeks, then reduce to rainfall-only as roots establish. Bahia's deep root system develops quickly once seedlings are established.
Mow for the first time when grass reaches 4 inches, cutting to 3 inches. Use a sharp blade. Avoid heavy traffic for the first 8 weeks. Apply 0.5 lb nitrogen per 1,000 sq ft at 6 weeks after germination. A full bahia stand takes one full growing season to fill in completely.
