DIY Compost Bins

Part of our green house project was creating a compost system to supply nutrient rich fertilizer for our crops.  After a bit of Pinterest browsing, I came across an idea that used plastic barrels raised on a stand so they could be filled, rotated and emptied easily.  I showed the picture to the Hubs and he whipped me up these.

I placed them right behind the green house where they get full sun exposure and there’s extra room for the stand supports. Although they currently sit on a slight incline I plan to remedy that when I add gravel around the green house so that they sit level.

The design is fairly simple.  He cut a panel door in the side of the barrels and created holes for the metal rod to go through the center of each barrel.  In a stroke of genius he added a weight to the opposite side of the barrel from the door so that the hardware wouldn’t cause the barrel to always rest with the door upside down.  He also added several large bolts that protrude into the barrel from the outside to help with the mixing process when it’s spun.

I’m still figuring out the right ratios of brown and green material and haven’t been great about keeping it damp to aid in the break down, but it also hasn’t been very warm here this summer so I’m not sure that if I had I would see much difference.  Luckily there’s never a shortage of material to add to the bins so we’ll continue the trial and error method with a bit of research until I get it just right.

If you compost I’d love to hear your tips and tricks both for cultivating the pile and using the resulting material in your garden!  Leave me a comment with what works or what doesn’t for you – it might just be something that helps me decrease this learning curve. 🙂
