On a hot day, water sitting inside the hose can be scalding hot.
If your hose sits in direct sun, it can be hot enough to burn you, OR the plants you're about to water. Let the water flow out before you start: point the hose into the street, or the driveway, or the deck, and flush out the scalding water until it flows cool to the touch. Then it's safe to water your delicate plants.
My husband didn't know this, I remember when I learned about it. I'm guessing it might be worth sharing.
Stay cool this weekend girls!!!
