This is the question we hear more than any other: “I had it seeded before and it didn’t take.” If that’s happened to you, there’s almost always a reason — and it usually comes down to one of a few things.
The most common culprit is timing. Seeding in spring sounds logical, but cool-season grasses — the only type that survives Long Island winters — need to establish before summer heat arrives. Spring-seeded lawns often don’t have enough time. The fall window, from late August through October, is when soil temperatures are still warm enough for germination but the brutal heat has broken. That’s the window that works in Suffolk County.
The second issue is equipment. A broadcast spreader drops seed on top of existing turf or bare soil with no real soil contact. A lot of that seed never germinates — it dries out, washes away, or gets eaten. We use a professional seeder that opens the soil and places seed at the correct depth, which is why our germination rates run 75–85%. That’s not a guess — it’s what the equipment delivers.
Third is seed selection. Suffolk County’s coastal climate, sandy soil, and cold winters require specific cool-season grass varieties. A generic national seed blend formulated for somewhere else won’t perform the same way here.
