I now understand and will add this to my "to do" list come June.

Thanks!

OK, another question. ??? When we had our landscaping done recently, they put down a black weed fabric under the stone. Will the epsom salt get through this? Anyone know?

Sometimes I mix my epsom salts with water, especially when there's no rain in site. If you put the salts on top of that black weed barrier, it should dissolve when water hits it and go straight through the cloth.
The drip line is the ground under the outermost area of the canopy. On a tree it would be the ground directly under the branch tips.
