Pros: Cheap ($7-$8 at Walmart), easy to apply
Cons: Covers about half what it says. Works at first, then dies. Not for dry climates.
I bought about 10 bags (100 sq ft) of patchmaster. I had both small patches to fix, and some areas that were a couple of feet wide. I live in Colorado, so the sun is intense. Most of my bad areas are places that get sun most of the day. My shaded ares did not need repair. The product did not cover even half of what was claimed, but it is easy to put down. I planted in April. I hand racked the area and put down a bit of topsoil (miracle grow) before putting down this stuff. I used gloves, cuz it is just shredded news paper (you can see the print) with seed and fertilizer added. It gets blue/green stuff all over your gloves. I watered twice a day. Grass came up great, matching the existing grass wonderfully. Some areas grew faster than others, but I got grass wherever I planted. I mowed after a few weeks. I mowed 4 times total. I even fertilized as suggested with scott's plus after the recommended period. It looked great for a couple of months. Then the big areas started to die, and even some of the smaller patch areas. Only the smallest areas remained. I was watering normally every day in the evening. Now (august) it is all gone except a few areas that had really small patches. Any patch of size is once again barren. Increasing water did not slow or stop the decay. Maybe this stuff will work in a less dry climate, but not here in high desert Colorado. It says it is bluegrass seed, which is suppose to be good for my climate, but it did not get the job done.
