Here in central Texas, Sept. and Oct. have been very dry, with less than 1" of rain over six weeks. Most of our friends and neighbors given up on their gardens. We still have vegetables growing because we harvest rainwater when we get it, store it and use it to keep our plants alive and producing. We were talking to our local agricultural agent, and he said more and more farmers and ranchers were harvesting rainwater to water crops or livestock. They are doing it on a large scale, while we are harvesting on a small scale, but the benefit of having water when needed works for all of us. He said that it is important to have water when you need it, and in the near future, having water when you need it may be "iffy". If you are in an area prone to droughts, either temporary or long-lasting, you might want to look into harvesting rainwater for use during the dry times.
