Lawn Soil pH: When to Lime, When to Add Sulfur

Real calcitic lime in a bag small enough to handle — and small enough that you need to check the maths before you buy it for a lawn.
Our Verdict
The lime itself is the right material: calcitic limestone is what a soil test calls for when it says lime, and powdered acts faster than pelletised. The problem is size. Ohio State caps established lawns at 100 lb of limestone per 1,000 sq ft in one application, so a 6 lb bag treats roughly 60 sq ft at that ceiling — fine for a soil-test-driven spot correction or a bed, a false economy for a whole lawn. Buy this for a small area or a raised bed and buy pelletised by the 40 lb bag for turf.
✅ Pros
- Calcitic limestone — the material soil tests actually specify
- Powdered reacts faster than pelletised
- OMRI listed for organic gardening
- Small bag is easy to store and handle
⚠️ Cons
- 6 lb treats only about 60 sq ft at Ohio State's 100 lb per 1,000 sq ft ceiling — not a lawn-sized bag
- Powder is dusty and drifts; pelletised is easier to spread evenly on turf
- Lime works over months, not days — this is not a rescue product
- Never apply without a soil test: liming a near-neutral lawn locks up iron

Where This Product Matters
Matched against each state's actual disease, weed and pest pressure.
Colorado
Colorado hub →⚖️ Colorado soils are alkaline. Lime is the wrong direction here — CSU's amendment is elemental sulfur, not limestone.
South Carolina
South Carolina hub →⚖️ Centipedegrass actually prefers acidic soil, so liming a South Carolina centipede lawn without a soil test invites iron chlorosis rather than fixing anything.
Washington
Washington hub →⚖️ WSU limes only below pH 5.5 and caps established lawns at 35 lb per 1,000 sq ft per application to avoid lime layers in the thatch — a stricter ceiling than Ohio State's.
