I disagree. If Lester is trying to grow plants native to our area, the

generally prefer some amount of alkalinity. But if he or she is trying to
grow vegetables in the garden or any of the MANY not-exactly-native

plants
that can do well here but suffer to some extent from our excessive
alkalinity, the ashes will be of benefit. And recycling brush in the
city: (1) if Lester is clearing brush and burning it, this probably means
his/her property is outside the city; and (2) putting brush in the

landfill
really seems wrong to me. Instead, shouldn't we try our best to recycle

this
waste by composting or burning it (or both), instead?

The addition of wood ash will tend to RAISE the pH of the soil. That
is, make it MORE alkaline, not less. As T.H. noted, our soil and our
water are both quite alkaline and the addition of still more is
unlikely to be helpful. I agree that composting the brush,
particularly if you have a brush grinder to break it down, is a better
way to dispose of it. I frequently scatter ashes over the top of my
compost heap. Not an ideal solution, but it seems to help cut the
alkalinity enough and helps enrich the compost.


Burning's a waste; if you can't compost it, build a brushpile. Birds and
small critters will love it.

And, FWIW, brush and yard waste in Austin is trucked to Hornsby Bend, where
it's mixed with sewage sludge to make Dillo Dirt. It doesn't get
landfilled. See: http://www.ci.austin.tx.us/water/dillo.htm
