Hello, I have a question regarding Hydroseeding. My front lawn was completely destoyed by this years hot weather. A friend of mine owns a landscaping and lawn cutting buisness and is planning on hydroseeding this Saturday. He sprayed and killed the whole yard a month ago and it is complete dead. I hate to bother him with questions about this procedure as he is so busy and he thinks I bug him with questions, haha. So, what am I to expect from this procedure? Do you think he will bring in new soil? He told me to mark where all under ground wiring is as I have many lamp posts in yard.
