Ashful
Minister of Fire
Does anyone spread the ashes on their lawn to lower the soil acidity? I heard that it's good for the grass, similar to an application of lime. Aparantly it also is a good source of potassium for the grass.
I've screened my ashes with a fry basket and have about three 5-gallon buckets of nice fine powdery ashes.
Curious to hear from someone who has tried it though. Any thoughts or suggestions?
I haven't looked into this, but I'd be surprised if the amount of ash generated by one woodstove contains enough base to make any difference over a large area like a lawn. I use dolomatic lime to the tune of a few thousand pounds per acre, when my soil approaches the low end of the ideal pH range, and even that only bumps the level a few tenths of a point.
If the ash contains enough base to actually change pH with the sort of volume any one of us produces in a year (100 - 200 lb?) it would have to be so basic it might burn the lawn. It would be a small area treatment, at best.
