Under Siege? Not Really, Just Go For A Walk

I have no trouble with people buying chocolates or wine instead of flowers to celebrate anniversaries, birthdays or peoples’ lives. We should all have choices. However, the other night I felt like I was entering the Republican caucus. I was minding my own business by the television set and became more than a little upset.

Fertility should be at least 150ppm nitrogen, but avoid ammonia in the fertilizer. Plants are best grown at a somewhat higher pH than usual, between 6.4 to 6.8.
