That's also a cool method, Brownrexx.
Tx for info about the mulch Svalli. I spent a few hours looking at different types last night - I'm amazed there are woven plastic fabrics that are rated to last up to 25 years.
It would be so worth it, although you do have to burn the holes or else they unravel.
I think this is what PH and PMcG are using for garlic.
I had some woven blue plastic tarps when I was first cutting wood here.. my goodness they didn't last more than a couple of years, and I literally spent.. days I guess if not weeks of my time trying to pick up the million little blue fibers that scattered everywhere.
Something that lasts long is the best choice, but I will need some reassurance it can survive our freeze and thaw winters.
One thing mentioned about the woven stuff is that it allows air and water through. But you had success with a solid piece as well, and no drip irrigation - that's good to know.
Garlic and potatoes are two crops that rarely ever get watered even once during the season here.
