I am a newbie on this forum and plead ignorance, but I have two problems.1 I live in Las Vegas, and wonder what special precautions I need to take to protect my plants from the blistering heat. I now have them on a covered patio, that is sunny in the morning and shaded in the afternoon. Our weather forcast for the end of this week is for temperatures in the 90's for Saturday and Sunday.What can I do to help my tomatoes when the temp gets to 110-112??? Problem number 2, on the profile section of the applicat to sign up, the age thermometer doe not go down low enough for my birthday.I was born in 1929, and 1930 is the lowest age shown. Please don't hold this against me. Thanks for your help.
