Have some questions for you all but first I wanted to say I hope everyone had a wonderful Christmas. I did. Anyways, I have this client that asked me to do a renovation on her lawn and I agreed. As you can tell this is my first one. I'm going to kill all the grass and then go over it with an overseeder. But is it neccessary to kill the exisiting grass if I use an overseeder? I'm basing this question on the fact that my local rental stores will have one. Then of course I will apply a good starter fert to it. Irrigation in place so it will be easy to keep moist. I'm charging her $45/sq.ft. + Rental fees for this-does that sound reasonable? I thank those who wish to help me-I have done a couple extensive searchs aleady that have helped alot. I just wanted to run this by others before I perform this in the spring. THANKS!
