Ash can be found in abundance around the home. There is charcoal ash, ashes from the fireplace or fire pit, and ashes from things you burn such as paper. We had 23 years of old tax records, receipts, and daycare enrollment forms in our attic and that’s far too many to keep.
We could have shredded them, but that would have taken a month. So for faster disposal, while protecting personal information of myself and all of my past clients, we burned them. We spent a day burning in a barrel and enjoyed the fire by roasting marshmallows and sitting around it watching the flames.
In our city, we are allowed to burn recreationally so we did it for a family activity. Of course on a Saturday when the kids weren’t here.
How to use ash in compost
Using ashes in compost can be tricky. If you use too much, you make the pile too alkaline. If the compost or soil in the garden is too alkaline, it prohibits the plants from absorbing iron which can cause deficiencies. You can layer the ashes in the compost and it will add a ton of lime and potassium to your compost which is great for garden plants.
Spread 1/8 inch of ashes on the pile, then 3-9 inches of browns or carbon materials, then 3 inches of green such as kitchen scraps. You can also just compost paper without burning it first in the same way and with the same effect.

Ashes from burning paper are also good to use. Cardboard ashes are good for the garden. And ashes from straw or other dried grasses are good as well.
Ashes from charcoal should not be used in the garden as they contain chemical residue that could harm your plants. You also don’t want to be eating chemicals.

Experiment with using a little bit of ash in your garden if you have some that you need to use. We are doing that this year and our cole crops or cool-season crops are growing like gangbusters. I’ve also not had any slugs in my lettuce like I usually do. Hopefully, as the season moves on that will last.
We sprinkled a tiny bit on our beds and put the rest in the compost to break down and add potassium later in the season.
