What to do with your leftover BBQ ashes? Why not use it in your garden?
Ashes are leftover 'un-burnable' minerals such as potassium. It will help your garden, especially if your soil is too acidic.
On the other hand, you should not add wood ash to your soil/garden under the following conditions:
- If the ashes came from briquettes rather than charcoal lumps (some unknown additives may have been introduced in the manufacturing process).
- If you have lots of meat and fat drippings in the ashes (attracts pests and is not good for the soil).
- Your soil is already alkaline.
- If your plants love acidic soil (berries).
The best advice is to buy a soil pH meter, understand what type of plants you want to grow, and measure periodically.
