Our Review
Scotts PatchMaster is purpose-built for one job: repairing dead patches. It's not a lawn renovation product. It's not for new lawns. It's for those ugly 2-foot bare spots where your dog killed the grass, the sprinkler head flooded an area, or disease took out a section.
The 3-in-1 formulation (seed, mulch, fertilizer) is the right approach for patch repair. The mulch layer retains moisture directly around the seed — critical for small-area repairs where the surrounding turf draws moisture away from the seeded zone. The starter fertilizer primes germination without burning seedlings. The result is faster, more reliable patch establishment than bare seed on bare soil.
At BSR 121, this is one of the most-purchased repair products on Amazon. The 10 lb bag covers up to 275 sq ft — enough for 2-3 typical dead patches or one larger repair area. Germination in 5-7 days under good conditions.
The limitation: this is a sun and shade blend, not a dedicated shade product or warm-season product. If you're repairing bermuda or zoysia, you need the Scotts EZ Seed Bermuda instead. If your patch is in full deep shade, Pennington Dense Shade is the better match.

What the Community Says
Common perspectives from the lawn care community
“Put down Scotts PatchMaster Lawn Repair Mix Sun + Shade last fall and the difference from my old lawn is night and day. The color alone makes it worth the premium over big box store seed.”
“I have a lot of mature oaks and was skeptical anything would fill in under them. Scotts proved me wrong. Not perfect, but way better than what I had before.”
“Perfect for someone who doesn't want to obsess over their lawn 24/7. Threw it down, kept it watered, and it came in thick without me babysitting it.”
