Re: RE:CULT: overhead watering vs rainfall


I want to add another variable to the mix (not that there's a lot we 
can do about it):

In my town, the water is TERRIBLE; the minerals in the soil make 
crusts on everything in sight.  So when my gardens begin to die by 
August-September, with the same care as before, someone suggested it 
was the water.  We have little summer rainfall too, so I have to 
water almost daily to keep companion plants alive.  (I'd water much 
less if I were dealing with iris only.)

Therefore, overhead and drip watering is the same water, which ain't 
the best.
