Lots of dead patches, no worms in lawn!
I have a tall fescue lawn, in the mojave desert. I have heavy clay soil, but amended about 20% with good compost to loosen it up. I seeded last spring and it grew great, nice and green. I aerated last fall, as well as fertilized and overseeded. I fertilized again in april, and dug up a couple dead patches and re-seeded those. I still have a lot of dead brown patches.
When I dug up a couple of the patches that were dead, there were no grubs or any visual of what would be causing the problem. I also noticed there are no worms in lawn at all. I think I need to get some worms in there to help loosen up the soil since it's such compacted clay soil (even with compost). What's the best route to take here? We're still in the 70's right now, maybe 80's by next week. But by the end of June we'll be close to 100 degrees outside.
Where can I buy worms to put in my lawn? Can you buy them dried up online, then when they are re-wetted they come back alive? Just throw them on top of the lawn and water them in?
