I live in northern PA, and our winter temps can go down to 20 below. My question is about ant hill dirt. I know where there are a few large ant hills. Is this dirt safe to add to my garden?
I would avoid using this dirt in the garden simply due to the possibility of there being unhatched eggs or remaining ants that may come along with it.
I read the article on using wood/fireplace ash in compost or directly in the garden, and it was very helpful, especially in regards to what type of wood was burned, but what about charcoal ash from the bbq?

Typically, it is not recommended to use ash from BBQ charcoal due to the chemicals that are used to create it. It is best to pass on using this in your garden or compost.
