Why Choose Drought-Tolerant Grass Seed and Mulch for the Southwest?
Before diving in, let’s arm you with the essentials. Southwest lawns (USDA Zones 7-10) demand warm-season grasses like Bermudagrass and native mixes that root deep (up to 4 feet) for water access, paired with mulches that lock in hydration and cool soil by 10-20°F.
Key Factors for Informed Decisions
- Drought Tolerance: Grasses that go dormant (brown but alive) in dry spells and rebound fast; mulches reducing evaporation by 50-70%.
- Heat Resistance: Thrives in 90-110°F without scorching.
- Soil Compatibility: Handles alkaline, sandy, or clay-heavy dirt common in AZ, TX, NM.
- Maintenance: Low water (1-2x/week once established), minimal mowing, weed suppression.
- Eco-Benefits: Water savings align with restrictions; natives boost pollinators.
- Cost vs. Value: Upfront prices balanced by longevity (5-12 years for mulch, perennial grasses).
