Hi Paul, I tried your suggestion on the worm holes. The grass seed came right up and I think its spreading. I used fescue. I couldn't dig 2 feet deep because it's under a tree, so I dug as deep as I could, about a foot. I only dug up 1 worm in the process. I also tried it yesterday in the front yard and didn't find any worms at all. One of the holes I dug was 2 feet deep because there was an old fence post there. Also, I used this same method to transplant some monkey grass around a tree. looking good so far! Thanks for your web site!
