Teddahlia
Ted, I love your dahlia knowledge and stories! - and of course, pictures of your gorgeous dahlias. Will try to never complain about the measly 80s here in NW Wa state on this island. 90 rarely happens. But one year it went up to 100 degrees with high humidity on July 4. I'm from Phila. area and loved the steamy hot humid summers there in my youth. I felt homesick but happy to see that high humid temperature, put on my wide brimmed straw hat and a gallon of water, and went to a garden job in a lovely dahlia patch that day and enjoyed sweating and drinking and watering - and the shade of the dahlia plants.
It would be different if it were a regular occurrence as it seems to be now in the west. (and many other places.)
Condolences to all of you who live in hot dry heat. One would need automatic timed watering there. Hoping the heat wave breaks soon and you all stay safe and hydrated.
