Bob, I'm glad that you were able to get your timers set up to water when you are not able. But as you said, it's a necessity because of other obligations. I do hope that your load lightens soon enough, so that you can get back to regular gardening chores.
I have a similar problem with aging parents, who won't accept their limitations, and look forward to setting up an irrigation system. I've been having problems keeping my asthma under control, and that has put a big dent in my gardening this season. But, I'm hoping that having a home nebulizer (for breathing treatments) and remembering to wear a mask when working outdoors will take care of that problem. Wishing you well in your gardening endeavors with the arrangements that you do have in place.
Stone, you are right about people being spoiled with A/C. I normally work outside during the summer, but with health restrictions, I've had to cut that back and stay inside more. I just wear long sleeves with the air on and take a light sweater with me when I have to go shopping or in a public building for long. Here in SC and near the coast, we have excessive humidity levels along with the heat that creates a problem with staying outside very long this summer. It can be a dangerous combination.
