I have had four pine trees removed, but because of their location the tree people cannot use the grinder to get rid of the stumps. I would like to remove them without using harmful chemicals. I heard you could put lime on them. I could chop them out,but my wife does not like the idea ( possible heart attack). One time we put a wine barrel on top of the stump with some flowers in it, and eventually the stump rotted, and we could pull it out with our hands. Location does permit this method. Any suggestions.
Thanks
Tom
