Planting Instructions
To plant Argentine Bahia grass seed, start by preparing a firm seedbed in the spring or early summer, then sow the seeds and maintain consistent moisture. The entire establishment process is low-maintenance but requires patience, as the grass can take several weeks to germinate and fill in.
Site Selection
- Sunlight: Choose a location that receives full sun, as Argentine Bahia grass thrives with at least eight hours of direct sunlight per day.
- Climate: Plant in the late spring or early summer. These warm-season seeds germinate best when soil temperatures are consistently above 65°F. Avoid summer planting, which can lead to weed issues, but fall planting may be possible in very warm climates
Soil preparation
-
Clear the area: Remove all existing vegetation, debris, and weeds. Consider using a non-selective herbicide on actively growing weeds and waiting at least seven days before tilling.
-
Test the soil: Argentine Bahia grass prefers acidic soil with a pH between 5.5 and 6.5. Conduct a soil test to determine if you need to add lime to adjust the pH.
-
Amend and till: If starting a new lawn, loosen the top 2 inches of soil using a tiller or rake. For overseeding, simply rake to loosen the surface.
-
Add fertilizer: Apply a starter fertilizer based on your soil test recommendations. Wait until after the seeds are planted to apply nitrogen, as early application can encourage weeds.
-
Firm the seedbed: Lightly roll or cultipack the area to ensure a firm seedbed and good seed-to-soil contact. Your footprints should sink no more than 1/4 inch.
Seeding
-
Spread the seed: Using a broadcast or drop spreader, apply Argentine Bahia seeds at the recommended rate. For a new lawn, use 10 lbs per 1,000 square feet; for overseeding, use 5 lbs per 1,000 square feet.
-
Cover lightly: Rake the seeds gently to work them into the top 1/4 to 1/2 inch of soil. Do not plant them any deeper.
-
Use a nurse crop (optional): To prevent soil erosion and retain moisture, you can add a temporary nurse crop like brown top millet. The faster-growing millet provides cover while the Bahia grass establishes.
Watering and ongoing care
-
Water daily: For the first two to three weeks after planting, keep the soil consistently moist by watering daily with a fine mist. The area should stay damp but not soggy.
-
Be patient: Argentine Bahia has a variable germination period, with sprouts typically appearing in 10 to 30 days. Full establishment can take 2 to 3 months.
-
Reduce watering: Once the new grass reaches 2 to 3 inches tall, reduce watering to a deep, infrequent schedule of about 1 inch per week during dry periods.
-
First mowing: When the grass reaches a height of 4 inches, you can perform the first mowing, cutting it down to 3 inches.
