Very easy to do when you've got a clay environment and nothing drains. In fact, the clay holds the moisture for a lot longer than the sandy environment around here. For what it's worth, I'm 20 minutes north of the OP, so I'm pretty confident that I know the type of soil I have here by Cape Cod. Well, he's either got sprays or rotors and I've talked with him (not in this thread) about watering differences between the two and how sprays will need shorter watering times due to their ability to flood an area faster. Around here in our pure sandy environment, you need a lot of moisture. I've been in this industy for the past 12 years in this area and I'm pretty confident that our soil's water holding capacity is pretty much non-existant. Just because I didn't post a consideration for his soil type or growth pattern doesn't mean I don't know what I'm talking about. I think you underestimate where I live because I don't have my location listed as a state. Well, I live 20 minutes away from his town so I don't have to post about what's going on in his area as I already know this information. Yes, anyone can throw Nitrogen at a lawn and make it look good. After dealing with turf for 12 straight years, I'm pretty confident in what I see, hear, and deal with on a daily basis to make a pretty good judgement call on things. I ask a lot of questions before giving out information. I'm licensed to apply these products in Massachusetts, I hold a commercial certification in tree/shrub with the state of Massachusetts, and I also hold a dealer's license in the state of Massachusetts. I used to have also have a license to apply in Rhode Island but I gave that up as I no longer work in that state. Tupersan/Siduron is not the only way to deal with weeds and crabgrass pressure as Quincloric is another product but that's a conversation for another day. I will not get into a conversation on natural based products because I have never seen them work as effectively as people claim and neither have the Professors who teach their classes at U-Mass Amherst - of which I've sat through too many to count. Not really guessing when he's in my area and I know the conditions. That's your opinion Whatever you say. You're over 3,000 miles away in another state and recommending things that work for your area - none of which are effective for our area. It sounds like you're the one who's guessing on most of this stuff. Yes, I am a dealer for these products but that doesn't diminish my knowledge of what's going on. I can also recommend many products from other companies that we don't carry so that doesn't diminish anything either. Hell, I can show him how to improve his lawn with pretty much any company's products. It's all in the "Why's, How's, Timing of treatments, and active ingredients." Being a vendor for products doesn't make me illiterate or diminish my capacity to help steer people in the right direction.
