Okay so im planning on doing some lawns this up and coming season due to requests from snow removal customers. However I am in Northern NJ and not sure what kind of grass grows here... and from reading on this website i guess it really makes a big difference. Anyway my question is what kind of grass is in Northern NJ Bergan County and should i bag it or mulch it? I had someone tell me that if i mulch throughout the summer I will kill the lawn because of suffocating it... is this true? thanks!
