Spreading Wood Ash On Garden Beds - January 2024

Last week, I read this post from Lee Reich where Lee compares spreading their hardwood ashes to conjuring the dark arts and had a little laugh.  I also...quickly learned a bunch - including how wood ash is a good source of Potassium (the "P" in N-P-K) and how a garden amendment that I've heard about/read about - Potash - is (obviously) the root word from Potassium, but is made up (mostly) of Ash.  Hence the name.   Lee talks about how the spreading of wood ash isn't a precise project; rather just a thin 'tossing' of the ash on the beds does the job.   Because we burn a lot of fires during the Winter, we end up with a surplus of ash that I collect at a couple of intervals when I clean out the fireplace and ash bucket.  Over the years, I've posted about how I've spread this ash - around trees in 2019 and on top of some snow in the perennial beds in 2022 .   I ended up with a bit more than five gallons of ash from Cherry, Birch, Oak, Hickory and....well
