What are wood ashes (npk?)

as far as npk numbers which number is it?

wood ashes are good for flowering. high in potash (potassium)

so is it the middle number or last?

i think they act as a ph up also... dont quote me on that, but i worked for a xmass tree farmer last year and he said that the lumber mills would drop off tons of ashes on a piece of land to raise the ph of the soil for free. they do this because they run out of room for the ashes the guy was telling me...

Woodash does, indeed, "sweeten" the soil and is used to raise the pH.

I remember I had a bonfire randomley drunk in the middle of my moms yard one time then the grass grew there like 5x greener and faster for like 2yrs(she was pisstt lol) so I was like free organic ftw does it matter what type of wood I use (treated or not)?
