EZ Seed is the duct tape of lawn care — it's not the most elegant solution, but it works, and it works every time. The combination of grass seed, mulch (ground wood fiber), and fertilizer in one product solves the three biggest reasons bare spot repairs fail: poor seed-to-soil contact, seeds drying out, and no starter…

- Overseed bare spots once frost risk passes
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Mow at recommended height weekly
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
- Core aerate compacted areas
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
- Avoid walking on frozen turf
