Spreading Hardwood Ash on Clay Soil - March 2026

Image
The pizza oven bed that I created last year is full of heavy, hard-to-drain clay soil.  While, it may not be a perfect solve, I still laid down a patch of firewood ash (hardwoods only) on top of the mulch after I cleaned up the screened door fireplace for the season.   I've done this in the past like here in January 2024 and typically spread the ash around to different spots in our garden or just dump the bucket into the compost bin in the far back of the yard.   Here, below, is the ash on the pizza oven bed: I need to lay down some organic material on this bed in the next few weeks ahead of planting dahlias here to give them a better shot at success.   The other thing I've done that involves ash is doing some small in-place burns with my mini torch.  I'll get out there and do some of these around the beds, too.  

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 a...

Spreading Hardwood Ash As Tree Fertilizer

'Tis the season for fireplace burning in our house - and likely in yours.  That means that you'll have to deal with the ash that gets left behind after the wood burns.  We burn hardwoods exclusively (so far this year, we've burned Cherry and Birch) and that means we end up with hardwood ash.  Turns out, it has value in the garden as a soil conditioner and fertilizer.    According to the Oregon State University (Notice...I did include *the* for those other OSU lunatics) Extension office , hardwood ash can aid in making the soil an environment that supports plant and tree growth.  From the OSU Extension article : Because wood ash is derived from plant material, it contains most of the 13 essential nutrients the soil supplies for plant growth, according to Dan Sullivan, OSU Extension soil scientist.  "When wood burns, nitrogen and sulfur are lost as gas," Sullivan said, "but calcium, potassium, magnesium and other trace elements remain. The carbo...
