Hi! Just wanted to thank you for the organic lawn care info. We took your "weird idea" and did our own version. We dug out plugs in our lawn about 1 1/2 ft. by 1 ft. and then dug down about 1 1/2 ft. into the dense CA clay. Tough work! We mixed our homemade compost with the clay and refilled the hole, placing the plugs back into the soil and watered them in. It's been about a year and a half -- you can tell where we've worked--the grass is green, fast-growing and more drought-tolerant. This is our rainy season lawn improvement project. When dry season comes, there's just no working with that clay! I can only speculate on the chemical abuse it may have received in seasons past, but no more! This is just to get a good foundation going. Once the soil is healthier we'll just do the "mow high & fertilize" thing.
