Most lawn diseases are fungal issues correct? Other than that the problems are caused by other issues such as pests, compaction, poor soil conditions? Am I right in this theory? And then... the NPP will solve most of these too correct? *Disclaimer: I fried in the sun today so if that is a stupid question I apologize. I was going to hire some help but thought I would tuff it out and do the work myself and keep the money.
