I found a way to keep hydrangeas from wilting in a heat wave
We had a big wedding order last July in Austin, and the forecast said 105 degrees. I knew the blue hydrangeas would be mush before the ceremony. My usual trick of cold water and floral foam wasn't cutting it. Out of pure panic, I filled a spray bottle with ice water and a single drop of clear dish soap, shook it up, and gave the blooms a very light mist right before they left the shop. I told the delivery driver to keep them in the coolest part of his van. The bride texted me a photo three hours later, and they still looked perfect. The soap seems to make the water stick to the petals longer, giving them a bit of a cooling shield. I've done it on four events since with the same kind of weather, and it's worked every time. Has anyone else found a different trick for extreme heat that doesn't involve a walk-in cooler?
