How do I care for my curling Hibiscus flowers?

Curling leaves can be a sign of drought or salt stress.

Yes I denitely think it is to dry soil, salt only happens when you live near the sea. Or after a snowy wintertime using salt to prevent slding and falling, I think.

Don’t know for sure; but, I just read that this same thing is happening with roses. Their advise was to dig down 6 inches near the roots to see if the dirt was dry or damp. If too dry, they are not getting enough water!

The flowers themselves only last one day. It doesn't matter if you pick the flower and put it in your hair as Hawaiian girls do or if you leave it on the plant. It will still last only one day. Enjoy them while you can. They are beautiful

too little water the leaves will be drooping down; it they are not it's not too little water, try something else.

Be careful when you water. Water at the base of the plant. Do not get the rest of the plant wet- unless you are using rain water. Also do not water with COLD water from the tap-allow water to warm to room temperature first.

They definitely need WATER!

How do I keep rabbits from eating the leaves and flowers??

Janet, I can see your plant looks healthy. It's not how you are watering. It is simply that the Hibiscus flower only lasts 1 day
