Is this true?
I have some friends who used to live in Phoenix, AZ. We were talking gardening recently and I was complaining that none of my "hot" peppers I planted last year got hot, except for the TAMs which were supposed to be mild. (I planted jalapenos and Anaheims.)
I grew them all in pots and got tons of beautiful peppers. Just not hot. My friends told me that I was overwatering the plants. They said in Phoenix, they never watered peppers except when rain came. This is news to me and I consider myself an experienced gardener.
