The bed was actually put in two summers ago (counting this summer) but due to circumstances I couldn't take care of it (or the rest of the garden for that matter) all summer and it became overgrown with weeds. So I decided that I would put down the cardboard and chips to cut down on the growth that had established roots. I dug and scraped as best I could but no way I could ever get all the rooted weeds out. By covering them and then preening in the spring I hope to have a decent looking garden. Plus I am now investigating having plants in pots that I can put on top of the chips between the larger plantings. Iris, lilies, geraniums, begonias, nasturtiums do really well under those conditions (pots). And I can move them or replant much more easily.
Got two more bags of chips today. So will continue the process while it is clear and crisp.
