Fall Lawn Fertilizer
Scotts Turf Builder WinterGuard Fall Lawn Food (32-0-10) Review
★★★★★ 4.6/5 editor rating
The fall feeding that does more than any spring one: root building and potassium winter-hardiness for northern lawns.

Our Verdict
For cool-season lawns, fall is THE feeding season — this is purpose-built for it: nitrogen for root reserves, potassium for cold tolerance, no phosphorus to trip regulations. September plus a late-October repeat sets up next spring's lawn before winter even starts.
✅ Pros
- Purpose-built for the most important feeding window of the northern year
- Potassium hardens turf against winter stress and disease
- Phosphorus-free — compliant with fall application rules
- Sets up spring green-up without spring surge feeding
⚠️ Cons
- A timing product — wrong tool for southern summer lawns
- Fast-release portion still demands careful spreader work
- Respect state cutoffs (e.g. Pennsylvania bans applications after Dec 15)
