A gallon ziplock bag of unfiltered wood ash from the wood burning stove (cherry, poplar, ash, and oak) that heats my house.

Includes small lumps of charred wood.

Has a lot of uses - it works great as a soil amendment and fertilizer, use to keep slugs away, use it to make soap, spread instead of salt on snow and ice. I apply a thin layer to my garlic beds every year (see pictures).
