Mixing hardwood ash with soil?

I'm creating a group of amendments to mix together and add to my soil. I'm lacking on the potassium side and have already spent quite a bit on amendments. I have a fire pit though full of big hardwood, can this be added to my soil for K?
If so what would the ratio be in accordance to the rest of my amendments?
There has been cardboard and possibly some random things burnt and mixed in with the coal, would this be okay?

For the most part I'm using a 1:1 ratio for mixing my amendments together. I plan on making a soil batch for veg and for final transplant right before flower so the mixtures I plan vary slightly for the one sided amendments, i.e blood meal(6-0-0)

What I do with my hardwood ashes is to get them out of the firepit the morning after I have a fire. then mix them with pee. Just stir in enough to make a thick paste. I let that sit {in yogurt containers} for 2-3 months. Mix in rock dust or anything else that sounds good, and add to soil mix.

Edit: I haven't actually added any to my soil mixes yet. I just started a few months ago when I saw a You Tube video about it.

No pee needed but treat woodash as lime as it will raise your pH. I use woodash all the time

Okay I thought I read that somewhere too. So what would be the right ratios of mixing with this so I don't accidently nuke my amendment mix with potassium? Just go with a 1 cup to 1 cup like the rest? Then add between 2 to 3 cups of total mixed amendments per cu. ft.?

I use about a cup to 25 gallons of soil. Woodash is mostly calcium but you are right that it is high is K.

Ash is also very light with an Assigned NPK of 0-0-6 by weight. Using for years in and out with nothing bad ever happening. Top dressing is a fave here as it is very soluble. Burned off wood or grassy areas explode under all that ash. Ash was a very big export in Colonial times.

This may be a stupid question...but....what about ash from organic bud? I have a coconut shell (my ash tray lol) that's full of powdered white/grey ash ...might as well use it if it's beneficial

I vape and all my ABV goes to worm bin or my mix. With properly raised weed, there isn't much ash.

Ashes help keep bugs away too. A lot of buggy critters dont like to crawl or creep across it. Its best not to let fresh ashes touch your plant tho -- it could burn.

I'm hoping more so for something that will last a while in the soil, sounds like that might wash away fairly quickly, if I have to top feed I will though.
I saw some stuff at the garden store, forgot what it was, maybe something like "mirate of potash", anyway it said it was 0-0-60 and didn't have much mixing directions on the bag so I was worried about over doing it if I bought that stuff.
What about banana peels, how would I use those?

muriate of potash is a salt that only should only be used by certain chloride tolerant plants like celery and such I think. Potash refers to a potassium salt I think(dont quote me). Wood ash is not the same though and has potassium but it is not water soluble like processed muriate of potash.

Hardwood ashes used to be used to make Lye soap -- picture Granny Clampett with her big iron pot -- so you have to be careful. I have no idea if it will work on MJ but I always use it around my veggies. I do know it keeps crawling bugs away. Dont use fresh ashes and keep them from actually touching the plant.

Just add a light sprinkling. If you put down too much the shit stays around for a long time.

Why not fresh? And how old do they need to be? I just burnt a bunch yesterday and was probably going to mix up the amendments and soil with a few days, then it would sit for probably 3 to 4 weeks before being used

Nice to have ashes around. The town crew burned a big dead oak and it smoldered for days. I scooped up buckets full of ash later which has many sugar cube size charcoal chunks and maybe 5% sharp sand. Best ash I’ve ever had!!!!

You are good to go as the heat of combustion has already made all those fast chemical reactions already happen. So you now have K and minerals left after cleansing by fire.

Sweet. Yeah I think this is actually the 3rd day that it's been going, looked outside and almost nothing but a big pile of white ash but still has smoke coming from it lol I'm ready to bag up the ash and be done with it but don't want to put it out with water and wash away all the good stuff either. I guess it'll go out eventually lol

Do not water,

You leach hardwood ashes with boil water to make lye. It was a major export from the colonies in the 16 and 1700's. Lots of forests cut down and burned for that trade.
