BTW...let me add that this site is great. Thank you so much for the info!!
And, I wanted to add a little bit about what my lawn looks like now. There is is green sprinkled with some brown is the sunny areas. The sides look great (they get a lot of shade)
I do have one area that has gotten very patcy.
We recently had a million weed pop up. Not sure where they came from. Some was crabgrass (i think, i'm new to all of this) and the others were tall, fast growing grass looking weeds. My husband and I spend 6 hours over the past two weekends pulling them. We got a good deal, but will probably have to make another pass.
I don't know if that was the right thing to do or not, but I definely don't want to put down chemicals.
I did hire an organic lawn care guy to put down some treatments. Thought I'd let him go at it this first year and then I'd try to take over after. But, I'm wondering if, with the clay, it is a lost cause.
OK...here I go again - back to the infrequent watering...can I do that with clay? And, if I already have some brown patches, do I still just look at the healthy grass to see if it is curling to determine when to water next?
I don't know how long it would take me to dig hole...but I will tell you that the clay is pure. I'll get out the shovel this weekend and check to see how hard it is. It probalby varies in different locations.
