Bahiagrass
Paspalum notatum
grassBahiagrass is a warm-season perennial grass native to South America, widely used for pasture, forage, and low-maintenance lawns in subtropical and tropical regions. It is highly drought-tolerant, disease-resistant, and requires minimal fertilization and maintenance once established. The grass produces distinctive two-pronged seed heads and grows 24-36 inches tall.

Germination
7-14 daysSeeds begin sprouting; fine, hair-like shoots emerge from soil
Keep seedbed moist but not waterlogged for 2-3 weeks. Protect from foot traffic. Avoid herbicides during this stage.
Seedling & Establishment
4-8 weeksYoung plants develop 3-4 leaves and shallow root systems; grass is thin and delicate
Continue consistent moisture; avoid heavy use or grazing. Light fertilization with nitrogen can accelerate growth. Mow lightly if needed to reduce competing weeds.
Vegetative Growth
8-12 weeksRhizomes develop, creating dense turf coverage; grass reaches 6-12 inches tall with expanding root system
Reduce watering frequency as drought tolerance increases. First light grazing can begin once grass is 8+ inches tall. Mow to 3-4 inches if lawn use.
Maturation & Seed Production
Ongoing through growing seasonGrass reaches full height (24-36 inches); distinctive two-pronged seed heads emerge on tall stems
Allow seed heads to mature if seed production desired; otherwise mow to manage height. Mature grass requires minimal maintenance and irrigation. Establish regular mowing schedule (4-6 inches height for pasture).
Dormancy
2-4 months depending on zoneGrass turns brown and stops growing during cold winter months (zones 8-9) or dry seasons
No mowing or fertilizing needed during dormancy. Perennial roots survive cold; grass will green up again with spring warmth.

Common Pests
-
Tolerate low populations; cultural control through mowing and removal of plant debris; insecticidal soap for severe infestations
-
Maintain adequate plant health and vigor; apply Bacillus thuringiensis (Bt) if populations exceed economic threshold
-
Irrigate to drive them deeper; reduce thatch buildup; beneficial nematodes or organophosphate insecticides for severe damage
-
Generally minor; no control usually necessary; maintain good plant vigor
Uses
Livestock Forage & Pasture
CulinaryBahiagrass is a primary pasture grass for cattle, horses, and other livestock in subtropical regions. It provides nutritious grazing year-round in suitable climates with minimal management. [source]
Low-Maintenance Lawn Grass
HouseholdWell-suited for residential lawns in warm climates where it requires minimal fertilizer, pesticides, and mowing compared to cool-season grasses. [source]
Erosion Control & Stabilization
HouseholdThe extensive rhizome system rapidly stabilizes soil on slopes and embankments, preventing erosion in warm regions. [source]
Hay Production
AgriculturalCut and dried for animal feed; produces good quality hay with minimal inputs, making it economical for farmers. [source]
Wildlife Habitat & Food
WildlifeProvides seed food for birds and cover for small wildlife while supporting diverse beneficial insect communities. [source]
Harvest Tips
Bahiagrass is harvested for hay, pasture grazing, or seed. For hay: cut when seed heads appear, typically mid-summer. For pasture: graze when grass reaches 8-12 inches tall, leave 3-4 inch stubble for regrowth. For seed: allow seed heads to fully mature (brown color), then combine or hand-harvest. Mature seed heads shed seed readily.
Fun Facts
- 🌱 Bahiagrass produces distinctive two-pronged (digitate) seed heads that resemble bird feet, aiding seed dispersal by wind and animals.
- 🌱 Native to tropical South America, it was introduced to Florida in the 1920s and has become the dominant pasture grass in the southeastern United States.
- 🌱 Bahiagrass can tolerate soils far too acidic or infertile for most other forage crops, making it ideal for marginal land unsuitable for conventional agriculture.
