Grass clippings? Add with care
If you have a large outdoor worm compost bin, you may want to add grass clippings to the mix. One problem is that finely cut fresh grass often heats up to a temperature that is too hot for the worms! If you want to compost grass clippings, add them to one side of your bin so that worms can move away until they cool off. Another option is to precompost them in a separate pile before feeding them to the worms.
