So I took some very bad advice on how to make my blue hydrangeas vibrant blue. They were blooming white. It was SF Gate website said to mix vinegar with water. So I did that. HUGE mistake, it killed my hydrangeas. So I dug them up and the soil. Put new soil down and new hydrangeas, pink ones this time. They were doing so well. Here in Florida we have had so much rain the last almost two weeks. I wasn't too concerned until yesterday. My hydrangeas are turning black. I don't know what to do or if they can even be saved. Not sure if it's too much water, residual vinegar or both. I will never take the advice of that site ever again. Can someone please tell me if there is anything I can do?

Rotted due to too much water.

Your hydrangeas are right on the edge in zone 9. It is a combination of the intense sun and heat that will make them suffer. They need to be planted in the shade and kept from drying out.

Thank you Bill. I normally water twice a week for 15 mins. The rain here lately has been unreal. I have seen other hydrangeas planted out here in full sun. The ones I planted get morning and late afternoon shade from the house. I hope the rain slacks off soon because I have no where else to plant them. I am afraid moving them now will kill them for sure. 🤷🏼‍♀️

You are welcome.
I love coneflowers. They are rated to zone 9. I figured since I was in Cape Coral, Zone 10, that some how my love for them would safely bring them through. No way!!
They sautéed like onions.

You cant underestimate the intensity of Florida sun. Where you are the sun is almost directly overhead! And when it's near 90, for six months on end, it is hard to grow some of these things!

All the research I did showed it was hardy for zone 9. I used to live in Mississippi for 13 years. They grow great there too and the summers were 115 degrees literally and would snow in winter. I was so glad to move back home to Florida.
