I just found this thread. I live in east Texas, it gets very hot here in summer. I have seen photos on this thread of lush blooming pots of geraniums. The ones I buy in early spring seem to wither in the heat, even with water. I would love to have some large pots of healthy, blooming geraniums throughout the summer and would really appreciate some tips on how to maintain this great plant in the heat - I just read it is a heavy feeder - what kind of fertilizer and how often, soil/water/light requirements - any tips and suggestions would be very much appreciated. Also, are certain colors better bloomers than others - seems the bright red does the best. Thanks!
