David, there are several kinds of plants we have to mist here in Arizona during June because it is so dry before the humidity his for our monsoon. Without a mist or humidity the spider mites move in and you can say bye bye tomatoes, grapes, and several other crops within just a day or two. Once the monsoon humidity comes in July our dew point stays up around 55 so the plants don't get quite so stressed.
Laura and Arlene, I just can't imagine living full time with your humidity! During August when the monsoon is in full swing and they start to irrigate the citrus down in Yuma(where my parents live), their dewpoint stays up in the 60s and 70s. I remember one day last summer it was 105 here and felt like 103, because of the low humidity, and felt like 113 in Yuma! Great for plants, bad for people like me!
