Buying Guide
Key considerations when choosing summer grass seed
- Sun exposure: Match seed type to your yard’s sun pattern (full sun, partial shade, or mixed). Tall fescues and Bermudagrass perform differently under heat and light conditions.
- Water and drought tolerance: Consider blends that emphasize deep rooting and water efficiency for hot summers.
- Soil preparation: Proper dethatching, aeration, and soil amendments improve germination and establishment.
- Overseeding vs. new lawn: For problem areas, select blends designed for overseeding; for bare patches, patch repair mixes can work best.
- Establishment window: Plant during cooler parts of summer or in spring/fall timelines when temperatures favor germination.
- Fertilizer vs. soil improver: Some blends include nutrients; others focus on root development and soil conditioning. Align with existing soil health.
