One of the very best things about worm composting is that it doesn't need to take up much room. It's the perfect way for an apartment gardener to make some rich nutrients for their plants. But the bins, they can be expensive. So make your own...
The San Francisco Chronicle has a great article on vermicomposting — great because it could potentially save you around $70. Instead of buying a worm bin for $100 you could make your own for under $30 following their simple instructions.
Apparently it also takes less than an hour to build! Let us know if you give it a try.
