We are doing an established grass area. Husband wants to put top soil and your directions didn't mention it. Please advise.
You do not have to use top soil with Pennington Smart Seed Sun & Shade Mix Grass Seed, but you can. You just want a good smooth, somewhat firm seedbed when planting the Sun & Shade mix.
