I recently moved my fire pit down to the new homestead and I may do a

0:18.8

celebratory bonfire here with some of the scraps that I have from the old place and that kind of brings you to the question

0:25.9

what if anything can you do with the wood ash that's left in your fire pit after you have a nice little bonfire with your family or friends.

0:34.5

Can you actually do something with that in the garden?

0:37.2

And the answer is, of course, yes.

0:39.6

Now, first of all, just a little disclaimer, you don't want to use ash from treated wood from

0:45.5

anything that may be in there that is being out of plastic or metals so use your

0:50.4

best judgment here you don't want to use ash from charcoal.

0:54.0

If you burn a lot of random trash, I mean, hopefully we're not doing that in our backyard.

0:58.4

But if you are, then that is not the type of ash that you want to use.

1:02.1

You want to use straight up wood ash. So if you have

1:06.2

that, what does it actually contain? Well, wood ash contains a lot of potassium and a lot of

1:12.0

calcium as well as magnesium and phosphorus, copper, and zinc.

1:17.8

It has quite a bit of calcium like I mentioned and so it can increase the pH of soil. So it will make your soil more alkaline

1:25.9

if that's something that you need as in raising the pH. So if you were to add it into a

1:30.7

pH of six soil it's going to bring it to a number that is above six.

1:35.3

So you need to make sure that you test your soil before you do that so you know you're not making

1:40.4

it some sort of massive adjustment up in the pH scale to get it to more

1:45.0

alkaline soil which again most annual fruits and vegetables do not want a

1:50.4

hyper alkaline soil like somewhere under seven, which is pH neutral, they would prefer that.

1:56.4

So is it a good idea?

1:58.6

Well, yes, it is, and in small amounts, I wouldn't be concerned about process and technique. I would probably just toss a little
