I have no experiance with seeding. I am about to seed my on yard at my new house. The yard now is infested with broadleaf weeds which I sprayed about 2 weeks ago and they are dieing. What do I need to do now to prep for spreading the seed? I have 5 lbs of centipede seed and need to cover 16,000 square feet. I have thought about using a tiller and tilling the yard about 1" deep spreading the seed and then racking it in. I had some one tell me to just spread the seed then cover it with top soil. I had a few more ideas like using a rake on the front of my wb for dethatching to scuff the ground but not shure if that would be enough. The other idea was to aerate and then spread the seed. Please tell me what will work best I do not want to waste the seed on something that will not work. Thanks.
