I keep mine in a metal "ash bucket" and when it gets full, I add to my garden. Ash = good fertilizer... just as long as it's just lump or wood ash. Wouldn't recommend it if you use a lot of lighter fluid.
You should be be careful spreading it in your gardens. You first should have the soil tested by an Agriculture firm. They can then tell you much you can put on your garden per it's size. Ex. 12 pounds per acre.
I was putting it on my garden too untill a friend up the road heard I was doing it. He came down and said he was doing it for several years and then started having a lot of problems with his veggies. He had his soil tested and had far too much of something that was produced by the ash.
Had to really treat his soil to get it back up again and that took a couple years.
So beware and play it safe. I now put mine in the garbage and it goes to a landfill.
As has been stated, wood ash is Extremely alkaline. The only nutrient value it has is potassium (K). And lots of it. But too much of a good thing...well you know.
If you add too much you will throw your pH levels high on the alkaline side. When that happens you plants wont be able to use the nutrients no matter how rich your soil is. A little goes a long way and that includes in the compost pile too. If you make it too alkaline then the bacteria which do the decomposing will die. And they will remain dead. An inactive compost pile will soon start to stink badly and what little decomposition you get will be an anaerobic slimey mess with very little value. I know...
Good to know, and it makes sense. I haven't had that happen yet, but frankly I don't get to light the smoker nearly often enough
. Maybe one day I'll be lucky enough to have time to make my compost pile stink.
Around here, I don't think you can add enough lime to really make the soil too alkaline though. pH ~4 are not unusual in NC. Your mileage may vary......
I hear some folks actually have naturally alkaline soil!!!!Who woulda thunk it?
Just like when you are adding lime, it's better to add smaller amounts more frequently than a large amount all at once. You want to mix it in, add water and give it some time to equalize a bit. Then if you need more you can add more which around here is "you always need more". If you add too much ash at once you're not getting that nice balance you're aiming for and instead are getting a big shot of alky, which if you're in an acid area is enough to stunt or even kill stuff.
I always just dump mine into the rocks that line my patio. Next good rain and you can't even tell it's there anymore. lol. probably because the MES doesn't produce a whole lot of ash each use. Now the wood stove on the other hand... that's a little more difficult to just dump out. A little goes in the garden, a little into the compost, a little here and there everywhere!
