FAQ’s on this Composter

Can You Buy Two and Put Them Together for One Large Bin?
You can connect two compost bins and get four times the volume. It will work great for collecting leaves. If you don’t fill the bin, you will likely need stakes to keep it rigid.
What Kind of Stakes Do I Need?
As stated above, the sides become rigid once you have several inches of material in the bin. However, if you need the bin to be more rigid, you might want to consider staking the sides. Most people find that any garden stake will work just fine.
Is it Hard to Get the Compost out of the Bin?
It is not complicated. All you need to do is remove the clips and unwrap the bin from the pile. Just remember to put the top layer of material back in the bin since it probably has not finished the composting process.
