|It doesn't decompose, it deteriorates.|
Landscape cloth. I don't care what you hear about it, what you read, or what anybody says. Don't do it. Landscape cloth was the all time stupidest gardening decision I've ever made.
I thought I could use it to conquer my wire grass. I thought I could eliminate it by smothering it out. I was lured by the so-called "guaranteed."
I spent days laying the stuff out and pinning it down.
I spent more days covering the entire area with wood chip mulch. The directions said 6 to 8 inches of their brand of rubber mulch, but I would never use that because it won't decompose. The rubber mulch should have been a red flag before I ever bought it.
But it's lightweight! (Flimsy). It is porous to let rain in through! (And sunlight). By the end of the summer the wire grass was happily beginning to poke its way up on through it.
By the following summer, the wiregrass had taken it over. Eventually it matted the landscape cloth to the ground. The only way to get it out was to dig it out. The "Guarantee"? Well, if you don't follow the directions to a "T" (i.e. apply those 6 inches of rubber mulch) any warranty is null and void.
This spring Dan took the tiller to it so we could plant corn in that spot. What a mess. The wiregrass matted landscape cloth bound up the tiller and left squillions of bits and pieces of petroleum based landscape cloth all over the place. I'll probably be picking them up till the day I die.
But at least the corn looks good.
Your turn. Have you made a worst gardening mistake?
