Hydrangeas

http://homeguides.sfgate.com/grow-zone-9-hydrangeas-23725.html

I'm sorry to say I have never been able to grow them down here in Florida either. They grew beautifully up in New Jersey. I just don't think they can adapt to the weather In zone 9.

Hi J, Here's a link that may help! https://www.gardeningknowhow.com/garden-how-to/gardening-by-zone/zone-9-10-11/zone-9-hydrangeas.htm

Good luck!

They should be mulched well and require lots and lots of water in the summer. I live in zone 8b Tallahassee and it gets very hot here. I have mine oriented so they get only early to mid morning sun. You might try planting them in semi shade. Don't forget to feed them.

And, YES, they can definitely be grown in zone 9

I am in Zone 9 too and it is just too hot and dry where I am, they have lovely foliage but never bloom but other areas of Zone 9 have been successful, just takes more work. You have a great link offered by Suzette, give it a try!

Hydrangeas need potassium and calcium. For this I blend banana peels, egg shells, and coffee grounds in the blender with a little water and feed them. Also, after they are done blooming, be sure to prune them back right away to encourage new blooms. Hope this helps, it did mine
