Okay, this is actually a thread on my personal lawn and not my customers. My lawn was orginated in fall '03. The lawn came back and look awesome in '04 but when late summer rolled around, I had an orangish iron-colored dust on the grass and when I would mow, it would get the whole front of my Grasshopper all orange. Also, the lawn started getting splotchy. I thought maybe grubbs so I put down some Grubb-X. Figured it couldn't hurt but I didn't really believe it. Now this year, the splotchy-ness (word?) of the lawn remained and with the dry conditions this year, the lawn just doesn't look healthy at all. I got a soil sample and I was low in N and Pot. Also, my pH was 7.2. I have just about 1.5 acres of grass. I put down 100 lbs N, 200 lbs PotAsh, and 200 lbs Sulfur. It seems that it has helped some. Now, I planted a bunch of trees last year and all were doing great. I have a type of silver maple (forget exactly which) out front that was one of the bigger trees. It came back great this spring and then about 2 weeks ago, it decided to die. So, now it has me thinking what the heck is going on. I am wondering if I am going to see the orange dust again this year too. Any thoughts???
