I'm looking to fill some patches on my lawn that are left over from last year's addition of a layer of topsoil. They seem resistant to the typical loosen soil, apply seed and water approach -- which I've done a couple of times. Each time, I get more coverage but there are still some patches. I want to finish it off with a convenient mix.
Costco has a bag of premixed dirt, seed, starter fertilizer (and likely peat) which seemed like a good idea. But, I choked on price.
I understand the guidance re. soil testing in comments... and I certainly have concerns with the amount of sand that was in the top soil (a neighbour is convinced that, with the amount of clay we've got, it will 'eventually' turn into a nice loam). However, I can't help but think that a convenient mix applied to the areas will address the patches where either the birds keep eating before it establishes or the sand was a bit concentrated, etc.
Anyone have a recipe they're able to share?
