Hello all I thank all of you for providing the information I was looking for. I think my only problem is getting the cool fluctuating temperatures. Cool weather is very limited here. Leo ,you mentioned the hot and humid summers with rain. Actually when I first moved here four years ago, there was a drought going on and you could go without rain for weeks or even over a month . Some folks on well water actually had no water at all. The last year or so, it's been more normal and I have resorted to poly over a shade cloth. ( I grow everything in pots so I can rescue the valuable and rare from hurricanes.). Some cactus seem to withstand the heat and rain, but the ones that turn out to be vulnerable are an unhappy surprise so I keep all succulents sheltered from the rain. Again thank all of you for the ongoing information. Cherry G. Cape Coral Fl
