We were able to get about 50 heavy (steel?)shelves from my husband’s work. <<<
What a wonderful find, should work for compost too.
Can you also use them for your canned and stored foods?
If you run out of the supports, try a dead tree limb, well planted in the ground and uses as a support for vines.
I have even had good luck with the bushy branches laid flat on the ground and used to support beans.
LOL, I like picking beans from a bean tree.
“Can you also use them for your canned and stored foods?”
We only got the metal shelves, no supports. I don’t know if they even have the supports or not - it was from the printing company hubby works for.
