tcjim, thanks for all the great information and patience with my lack of knowledge!
Im guessing the lime should be powder and not granules?
I have a question about the aerator they have there. I am just starting out, the aerator looks like it was bought used from the local rental place. I think it is missing something though... It is the type that you put block or whatever on for weight. The tines are "C" shaped. I dont see how you would adjust the depth on the aeration. There are wheels on both sides. with a lever on each. when you set them forward the aerator rolls on the wheels. But that is all they do. There are holes in the side of the aerator where you could possibly adjust something, but I have no clue...Is it supposed to ride right on the tines? Pretty bumpy that way...
