DIY Compost Box

Hi Friends,

On a beautiful cool day in Florida, I decided to go to my local Lowes and pick up some cedar wood to build this little compost box for my garden. I had some leftover cedar laying around from some Pickets I bought earlier in the year I used for Planter Boxes.This is a sloppy “How To” if you are a newbie to building, but hopefully it can give you some inspiration.


I Started with the Bottom of the box, this was made with some leftover Cedar Boards I had from an earlier project. I used 1×2’s along the sides with two screws going through each board.


The sides were made with (3) 1″ x 8″  Tongue & Groove Cedar Boards. They were actually cheaper in price to get the Tongue & Groove than the regular 1 x 8s.


Looking at the Inside of one the Side Walls.. I used a 1″ x 2″ on the length sides that were 1.5″ Shorter than the entire length. This is so that this Side Face will sit on the Bottom Face. (See next picture).


Two Side Walls Created! You can see now why the 1″ x 2″ on the Side Walls need to be shorter than the length of the entire Side Wall. It rests on the Bottom Face of the Box. I used 3 exterior screws along the bottom of each Side Wall to attach them to the Bottom Face.


The Front Wall of the Box is up! I made it the same way I made the sides, with (3) 1″ x8″ Tongue & Groove Boards. One Exterior Screw on each board on each side attaches it to the side Walls. I also used a couple screws along the bottom board to attach to the Bottom Face.


Constructing the Back Wall- This is the one of the uglier sides of the Box because at this point I was just scrapping together whatever leftover wood I had to make the rest of the box. I used come cedar pickets to build most of the Back Wall.


I used some of the leftover 1″ x 2″ to finish up the Back Wall.


Building the Top Face- I was really scrapping wood together here. This is probably not the best way to build the Top, Like I said I just wanted to use what I had laying around. I used Fence Pickets & leftover 1″ x 2″ Boards to hold things together. I left a big whole in the middle because I bought some Acrylic Glass to cover it up.


Putting on the Hardware!


I bought this Acrylic Sheet because I thought it would be a good idea to let heat in the box. I have no idea if this is true though, I know lots of Compost Boxes on the Market don’t have such a thing. I don’t know much about composting, but I know it takes heat for things to cook and get the decomposing process going, so I thought maybe this would help. We’ll See.


My final Product! I never measured it, it’s approx. 2′ long in each direction.

So It’s been about a month or so since I built this thing and I filled it up pretty quickly, mostly with leaves and pine needles, which I think will take a long time to break down. I’ll post an update if/when I get some compost I can use for the garden!
