What to know before hiring
- Most JoCo lawns are cool-season grasses such as tall fescue or Kentucky bluegrass, so fall (September into October) is the main window for core aeration and overseeding.
- Ask whether a quote is per visit or a seasonal program, and which applications (pre-emergent, broadleaf weed control, fertilizer) are included.
- Clay-heavy soils common across the metro compact easily; aeration helps water and nutrients reach roots.
- Confirm mowing height. Cutting fescue too short in July and August stresses it during heat.
Common questions
What does a lawn treatment program usually include?
A typical program spreads pre-emergent crabgrass control in spring, weed control and fertilizer through the season, and a fall feeding. Ask each provider for their exact schedule in writing.
Is fall really the best time to seed?
For cool-season grasses, yes. Soil is still warm and air is cooler, which favors germination and gives seedlings time before winter.
