Thank you for sharing your experience. May I ask you a question.....If my lawn is approx two acres how much money in chemicals will I use per year using your regimen? The reason I ask is I'm trying to figure out if it's cheaper to do it myself or to hire a company to do it.
Thank you again for the information,
I will answer as best as I can and I am not going to get a calculator. The biggest variance is going to be the difference between wholesale and retail pricing on fertilizers.
Figure you will need 300#s of fertilizer, 6 bags (coverage rated at 16,500 sq feet 50# bag)
If you go with a good 3 way commercial strength such as Vessel, Trimec, Trimec 992 or MecAmine D. @ 1.5oz /1,000 you'll need a little over a gallon.
I use T-zone but it is a LOT MORE EXPENSIVE but smokes hard to kill weeds like creeping charlie and the true yard scourge, wild violets.
I always use a non ionic surfactant to make herbicide work better and reduce drift, Li-700, 16oz/acre or a quart.
I spray Prodiamine 65WDG, a Pre emergent with broadleaf weedkiller at the same time, figure 2#s.
Go to Do my own pest control and you can figure out prices from there. 3 way herbicide you might be able to get at a Co-op or golf course supply if they will deal with you.
