I guess this is the appropriate forum for this question since it is maintenance related... My current "compost pile" is basically a hole in the ground that I dug. It's not very effective. I really don't want to buy one of those plastic bins that your turn with a crank. I am wondering if I can build a simple frame out of 2 x 12 lumber (untreated) say maybe 4 feet by 4 feet and only 12" high which will basically be just the width of the board. Would this serve the purpose of a composter? Will it need a cover, like plywood? I'll be throwing a lot of chick poo and pine shavings in it plus other normal compostable items. I understand that I may have to replace it in a couple years due to not using treated wood. With the low cost, I'm ok with that. I'd rather not use treated wood since I'll be using all that compost in the garden and around fruit trees.
