If you're like me and wondering what to do with your used, unwanted cardboard boxes, they can find a second life as mulch for your garden.
I pick up appliance boxes from the appliance store. I only use brown cardboard with minimum or no ink. I peel off the tape, open the box up flat and lay in in my paths or on new beds that I want to keep growth-free. I find if I use smaller pieces and there is any crack between pieces of cardboard, weeds will find a way.
Paper degrading can lead to slightly acid conditions so you may want to use a bit of lime.
Violet Lane writes that she uses cardboard to start new beds over the winter. It's not pretty, but it's practical. See pictures here. While I probably can't get away with it given my homeowner's association rules, maybe shredded or covered with wood chips could work. Thoughts?
