Thanks for the link, Seedfork.
That is my thinking also.
I have considered landscape fabric, but I've always seen weeds eventually poke through or around it.
The fact that it pretty much kills everything underneath is a no brainer.
I plan to slowly, but surely put in some type of raised beds with mowed lawn in between.
I have lots of fence posts from when we had horses here, and since they are rated for underground use,
they should hold up fine being laid down like a "log cabin" type raised bed.
I think those worms that are as thick as your finger are "night crawlers." I have some here along with the other earthworms.
