Never seen anything like that, Mark! But there was a period last spring when I was out late a time or two and heard that strange rustling in the leaves on the ground - loud enough that I thought it was mice- but I could never see anything (except some leaves moving) and realised it was all over the place! In daylight I could see on some beds that had a light coating of leaves, that the dried leaves had been pulled into regularly spaced little piles!

LOL! The Year of the Worm! Sounds like good rich soil and a VERY WET year! Yes, I fondly remember the spring of 2011 with its great Lake Peden. I imagine most of the worms here just plain drowned. As another point about root invasion: The tip of a root leader is like one cell thick. That can get through a real small hole. When it does, if it finds nice goodies on other side of hole, the root will grow large forcing a larger hole in order to devour nice goodies; something to consider when planning barriers in soil.

Mark, I have that number of earth worms in my compost heaps!
It is different species of worms in different kinds of soil. I think I have 10-12 species of worms in my garden.

Given the general lack of enthusiasm for landscape cloth, I've decided not to use it. My thanks to everyone for the info & advice!
