Yes, thanks Arlyn.. good info on Alfalfa..
I used to mess around with Cottonseed meal and kelp mixed into my potting soil.. I bought a big bag of green sand once because Martha Stewart was raving about it. It was supposed to prevent peach leaf curl (hahahaha!).. Then there was the bat guano.. I've tried all sorts of things over the years, but I can't remember anymore if I tried Alfalfa. One of the nice things about getting older, is having everything be new again... and again..
