When we moved to the apartment, we found the holy grail of cardboard for all of our gardening needs. Our building has a special recycling area that keeps empty "clean" boxes separate from the regular trash. I guess with the amount of residents moving in and out there are always a plethora of boxes, not to mention, everyone ordering mail order items and having boxes left over (gotta love Amazon!).
We went down a couple of months ago and picked up a bunch, loaded it all into the car and drove it to the farm to store in the barn. Then I spent an hour pulling off all the tape (always pull off the plastic tape, it WON'T break down) and it was ready for use.

I've used them in the raised beds for both the garden and the orchard. They kill grass and weeds better than anything I've found. Best of all, after a few weeks under the dirt, they just become their own compost as they break down.
I've used them to make the flower beds in front of the garden fence, it makes life so much easier. I liked having the 'flaps' to use behind the landscape timbers. It has kept the grass from encroaching behind the fence.

They looked great when they were first done. Then I just filled and topped it off with soil. The beds are doing great and so far, they are weed and grass free, a month out from building.

Most recently I used some in the front flowerbeds when I made them. It's a great way to not have to take up all the grass and weeds, this will just smother it out.
The next plan is to try just putting cardboard sheets down (in the future bee yard) with maybe some rocks or bricks on top to hold it in place and then hoping it will smother out the grass. Then I plan to just put soil on top and plant some flower seeds directly into the soil. No timbers around it or outline of a bed, just a "flower mound".
Anyone ever done anything similar?
