Ashes from the barbeque
I cleaned out the barbeque grill this weekend and got a good amount of ashes from last year. I remember my grandfather used to add wood ashes to his tomato garden and he had great tomatoes. Can I use these ashes from charcoal briquettes? I do use lighter fluid to start the fire, but I would think that has to be gone by the time the briquettes have turned to ash.
