This guide covers sowing Bermuda grass seed: ground preparation, dose calculation, sowing with the cross pattern technique, very light covering with compacting, and gentle watering with sustained moisture. Follow these steps to establish Bermuda lawn from seed with the cross pattern technique that prevents thin patches and the right watering for the early stage.
Product specifications
Cynodon dactylon (Bermuda) is the most widely sown warm-season grass in the world. Fine blade, dense, aggressive in spreading, it withstands heavy foot traffic and recovers quickly after mowing. Our seed comes hulled and coated with nutrient and fungicide for higher germination. The 22.7 kg bag covers 700-1000 m² at a professional dose.

Step by step for sowing
Sowing Bermuda follows the same general rules as Paspalum, with small variations in dose and temperature. The critical phase is the first 14 days: permanent moisture and the right temperature.
Prepare the ground
Remove vegetation, debris, and stones. Till to a depth of 15-20 cm (6-8 in) and level with a rake. In heavy or poor soils, incorporate coconut fiber substrate or organic matter into the first horizon. Water 24-48 hours before sowing so the soil is moist but not waterlogged.
Calculate the dose
The dose for coated Bermuda is 22-30 g/m² (4.5-6 oz per 100 sq ft), slightly lower than Paspalum because the seed is smaller and germinates denser. In areas with good preparation and abundant watering 22-25 g/m²; in demanding areas 30 g/m².
Sow with the cross pattern technique
Use a rotary spreader for large surfaces; sow by hand with cross dispersal for small plots. Divide the total dose into two halves, sow the first in one direction and the second perpendicular. This compensates for irregularities and achieves a more uniform distribution.
Cover very lightly and compact
Pass the rake very gently so the seed is covered with barely 3 mm (0.1 in) of soil. Then pass a light roller or press with a board to encourage contact between seed and soil, which is what triggers germination. Bermuda seed is even smaller than Paspalum seed: any excess depth drastically reduces germination.
Water gently and maintain moisture
Water immediately with a low-pressure sprinkler (not a strong jet that moves the seed). During the first 2-3 weeks, keep the soil moist at all times: 2-4 short waterings per day. Germination begins at 5-10 days with the right temperature (24-30 °C). From day 14 onward, space waterings progressively.
Bermuda excels for moderate-to-high traffic surfaces: family gardens with children, amateur sports turf, municipal green areas. If your project is for a football pitch or golf course with heavy traffic, consider hybrid Bermuda varieties (Tifway, Tifgreen) that are denser and more resistant than common Bermuda. For ornamental and residential use, common coated Bermuda gives excellent results.
Do not sow Bermuda in coastal areas with saline soil or watering with brackish water. Bermuda does not tolerate salinity above 7,000 ppm: within a few weeks it yellows and dies in affected areas. For those cases, use Paspalum vaginatum, specifically designed to tolerate up to 35,000 ppm of salinity without problems.
Complementary products
A successful Bermuda sowing relies on these products:
The coconut fiber substrate incorporated into the top horizon improves aeration and water retention for the germination phase. The coconut biomat is the essential covering if you sow on a slope or incline: it keeps the seed in position and conserves moisture. The Paspalum grass seed is the alternative for coastal areas with salinity, where Bermuda does not work.
Maintenance and care
Bermuda lawn requires regular maintenance to keep its density and appearance:
- Seed storage: in a cool, dry, dark place. Once the bag is opened, use it within a few months to maintain germination quality.
- First mowing: when it reaches 6-7 cm (2.5 in), cut to 3-4 cm (1.2-1.5 in) with a sharp mower. Bermuda benefits from lower cuts than Paspalum.
- Regular mowing: Bermuda grows fast in hot weather: cut every 5-7 days in midsummer, every 10-15 in transition. Never cut more than a third of the height in a single mowing.
- Fertilization: Bermuda demands nitrogen. Apply a nitrogen-rich NPK fertilizer every 6-8 weeks during the growing season.
- Aeration and verticutting: once a year, perform core aeration and verticutting to remove thatch (a layer of accumulated organic matter). It is essential for the long-term health of the lawn.
Frequently asked questions
What is the optimal time to sow?
In the Dominican climate, best between March and June or between September and October. Optimal soil temperature: 22-30 °C. Bermuda germinates quickly (5-10 days) in these conditions. Below 18 °C germination is slow or nil. Above 35 °C watering must be very frequent to prevent dehydration.
Why is my Bermuda lawn turning yellow?
Common causes: nitrogen deficiency (fertilize), excessive watering with waterlogging (space waterings and improve drainage), foot traffic in areas with soft soil (use a lawn paver in high-traffic areas), or watering with poor-quality water. If it yellows only in specific areas and the water adds salinity, consider switching to Paspalum.
How long does it take to cover the whole ground?
With the correct dose and proper maintenance: germination at 5-10 days, visible lawn in 3 weeks, acceptable coverage at 60 days, dense established lawn at 90-120 days. Bermuda is aggressive, spreading by stolons and rhizomes: the few bare patches that remain after the first germination close on their own in 2-3 months with regular watering and mowing.
