The heat has arrived and this year may seem unusual to you, but to have one of these extremely hot summers, that everyone wants forget, happens occasionally in Texas. Texas is no stranger to extreme heat any summer but if you were in Texas in 1980 as I was, you endured one of the hottest summers on record. I was working for Texas A&M Extension Service and I remember all the problems associated with that summer heat. We learned a lot about plant care during that time.
