Hibiscus problem

Our Hibiscus has been growing magnificently and looked really healthy until recently. Was hoping for super flowers but unfortunately the many buds won’t fully open and some are falling off too soon. Leaves also yellowing and falling off. Any advice?

    Buds drying up and not opening is usually down  to lack of water at the roots. 

    I see your shrub is in a pot. I suspect it’s not been getting enough water. 

    It wants to grow into a large shrub … have you  got somewhere you can plant it in the ground?

    In the meantime dunk that plant in its container into a deep trug full of water and leave it there for a few hours … then take it out and let it drain.

    Take a look at this recent thread … see how big this hibiscus is?

    Thanks. I will do just that. No space in ground I’m afraid but will put into a bigger pot before next spring. Will that be ok?

    That should help, but make sure you have an appropriate medium for it to grow in -not just compost  :)
    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...

    Bad News. The lovely hibiscus is just getting worse despite increased watering. Leaves turning yellow and just falling off. New Buds turning yellow and falling off. Flower buds that are pink not opening fully, some part opening then turning a darker purple then falling off. Something is definitely wrong. It was looking so healthy before the days and days of rain we had here in Bolton in August. 
    Please help as I want to do the right thing for next year.

    It wants to spread its feet, it need putting in the ground or at least a 60cm or more pot with garden soil.   It wants to grow into a tree it’s being stunted and it’s giving up.

    I had just the same problem with one,  I put it it the ground and it’s grown on beautifully,  unfortunately never had a flower on it.
