How to Grow Dallis Grass
Dallis Grass
Paspalum dilatatum
grassDallis grass is a warm-season perennial pasture grass native to South America, known for its productivity and palatability for livestock. It thrives in warm climates and moist soils, producing distinctive seed heads and lush foliage. This grass is valued for hay production, grazing, and erosion control in subtropical and warm temperate regions.

Germination & Establishment
3-4 weeksSeeds germinate within 7-14 days under warm, moist conditions. Young seedlings develop fine leaf blades and shallow root systems.
Keep soil consistently moist but not waterlogged. Maintain warm temperatures (70-85°F ideal). Protect from heavy grazing or mowing during this phase.
Vegetative Growth
4-8 weeksPlant develops more robust root systems and expanded leaf area. Dense tillers form, creating a productive sod. Bright green, coarse leaf blades are characteristic.
Maintain moderate moisture. Apply balanced fertilizer (10-10-10 or higher nitrogen formula) for vigorous growth. Begin light grazing or mowing when grass reaches 6-8 inches.
Flowering & Seed Production
6-8 weeksDistinctive seed heads emerge 2-3 feet tall with finger-like spikes radiating from a central point (digitate panicles). Flowering occurs in mid-to-late summer.
Allow seed heads to mature if collecting seed or promoting natural re-seeding. Continue adequate water and nutrients. Manage grazing to avoid trampling seed heads.
Seed Maturity & Dormancy Preparation
4-6 weeksSeeds mature and darken. Plant begins hardening off as temperatures cool toward fall and winter. Some foliage may senesce, but perennial plants remain living.
Reduce grazing pressure to allow plant rest. Avoid over-fertilizing late in season. Water only if extreme drought occurs. Prepare for dormancy in frost-prone areas.
Winter Dormancy & Spring Regrowth
8-16 weeks depending on zoneIn cooler zones (8-9), foliage browns and growth slows dramatically. In warmer zones, growth continues at reduced rate. Spring warmth triggers rapid green-up.
Minimal care during dormancy. Avoid heavy grazing in late fall. Early spring fertilizer application promotes faster warm-season recovery. Remove dead growth if needed.

Common Pests
-
Monitor for defoliation; allow natural predators; apply insecticidal soap or neem oil if severe; maintain healthy plants to outgrow damage
-
Usually minor on grass; remove webs if feasible; encourage beneficial insects; chemical control rarely needed
-
Maintain adequate moisture; apply water spray to foliage; use miticide only in severe cases; promote natural predators
-
and
(various species)
Improve air circulation by managing thatch; avoid overhead irrigation late in day; apply fungicide if disease severely impacts foliage; select disease-resistant management practices
Uses
Livestock Forage
CulinaryDallis grass is highly palatable to cattle, horses, sheep, and goats, providing nutritious pasture and hay. Its digestibility and productivity make it valuable for sustainable livestock production. [source]
Erosion Control & Stabilization
HouseholdThe dense root system and rhizomatous growth habit make Dallis grass excellent for stabilizing banks, controlling erosion on slopes, and preventing soil loss in moist areas. [source]
Wildlife Habitat & Forage
WildlifeProvides cover and forage for native wildlife including grasshoppers, quail, and other ground-foraging species. Seed production supports granivorous birds. [source]
Seed Production
CraftDallis grass seed is commercially produced for pasture establishment and is collectible by hand-harvesting or mechanical means for replanting or restoration projects. [source]
Nutritional Forage Quality
MedicinalResearch indicates Dallis grass forage contains beneficial nutrients and compounds that support animal health when properly managed; its nutritional profile is valuable for grazing animal nutrition. [source]

Harvest Tips
For hay production, cut at boot to early bloom stage (head emergence) when forage quality is highest, typically mid-to-late summer. For grazing, allow grass to reach 4-6 inches before grazing animals are introduced, and remove before being grazed below 2-3 inches to maintain productivity. Seed heads can be hand-harvested or mechanically collected 7-10 days after heads fully emerge and begin to dry.
Fun Facts
- 🌱 Dallis grass produces distinctive 'finger-like' seed head spikes that can radiate 5-10 points from a central axis, resembling an open hand—a feature that makes it easily identifiable in the field.
- 🌱 Native to South America (Argentina and Brazil), Dallis grass was introduced to the southern United States in the early 20th century and has become one of the most important warm-season pasture grasses in subtropical regions.
- 🌱 Dallis grass can produce high yields—under good management, it can produce 4-6 tons of dry hay per acre annually and sustain continuous grazing, making it exceptionally productive for warm-climate agriculture.
