| 0:00.0 | 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 |
