Hi everyone, I'm about to seed about 15000sqft at my house and have bought 75kg of blended seed. The soil is hard packed clay so I was going to bring in some topsoil and a few loads of horse manure, then till it all together, seed/fert and roll. NOW, I'm at the point where I just want it DONE! can I lightly till the clay (using skidsteer will tiller attachment) and seed/fert/roll then cover with straw, or should I add some nutrient to the clay first. I dug about a hundred yards out of my backyard to bring up the front yard due to a flooding problem. When this house was built they didn't do anything in the way of landscaping so I'm starting with a clean slate. What's the best fertilizer to use to help seed germinate? Is it necessary or can I manage without the added expense? Thanks for all your input! Matt Here's a few before of the backyard... you can see all the cracked clay and patchy grass. Will grass alone with a thick and healthy root system be enough to keep clay from cracking and opening up like this?
