permaculture

[Marimike6@cs.com]

The one class of plants I've found don't respond well to being peed upon are 
the conifers-- cypress, fir, pines, hemlock and the like. They turn yellow 
and 
lose their needles in fairly short order.

Other than that I think those urban environments-- alleys near bars, say-- 
that get lots of adventitious pee share a second problem that may be much 
more 
devastating to the flora... compacted ground. Wherever you get a lot of foot 
traffic you quickly get down to the broad leaved plantains, lambs' quarters 
and 
beggars' lice. And after that... bare dirt.

Break up the ground routinely, whenever it gets well compacted. Then plant 
nothing. Those weeds that quickly fill the space will, by definition, be 
comfortable with a urine soaked environment.
