Hibiscus, Advice Needed

I've never had much luck with Hibiscus, either in the ground or pots.

Here is my double peach on taken in January ...



... and here it is this morning ...



In the meantime, all the leaves dropped off and these new smaller ones have developed. But, stranger still, the double blooms are now all single blooms! :confused:

Any ideas? Thank you.

 

Its struggling at a guess, think I'd cut it down and hope for a new start.
But thats just me being drastic.

 

Well, you're always drastic, pete, but thanks for answering. Struggling for what? I contacted an American Hibiscus site and was told it needed constant watering ... we're flooding at the moment!

In the meantime I thought should I add some iron pellets?

But going from double to single flowers ..... :confused:

 

Hi Lol, if it`s really wet then let it dry out a bit also to encourage leaf growth give it a high nitrogen feed. David.

 

Thanks, David, we are now dry as hell! :D :D :D

I've moved it's location! :confused:
