Well, there is one of my boxes for my veggies next year. This one will be for my verticles and my long carrots. The boxes are built on a double thick layer of cardboard (I had a lot of flat boxes that we could not use -- too large for anything). They will be filled with my planting mix and seedlings, or seeds, planted directly there.
That orange stuff also has cardboard under it. It is a plastic, fake "mulch" weed barrier. I'm hoping to keep the weeds out with this. In any case it is really nice to walk or kneel on -- sort of cushy. I may put real bark on top of it and it won't wash off.
I meant that the cardboard boxes were too large to pack, or store anything in. They were left at our business by a former customer (now out of business) who used to ship machines in them that were lifted by a fork lift.
I was trying to figure out what you meant by “3 timbers high”, etc. Now it makes sense. That’s a nice box!
