Composting with Hay Bales: Build a Bin That Becomes Compost Itself

Hay bales make a fantastic compost bin: they provide brown material in summer (when greens abound), and the bale walls eventually decompose into the pile. Source spoiled hay from farms (end of season) or garden centers (fall decor).

How to Build a Hay-Bale Bin

1. Arrange bales in a square outline; add a second layer on back and sides.
2. Fill center with compost materials.
3. Low front allows easy turning; high walls retain heat.
4. When compost is done, cut twine, add bale straw to pile. Twine can tie tomatoes.

Herbicide Caution

Some hay is treated with persistent herbicides that harm food crops. Test finished compost: mix 2:1 with potting soil, grow beans vs. pure potting soil. If plants are identical, compost is safe for food gardens. If stunted, use only for landscaping.
