pruning Hibiscus

Can anyone tell me how and when to prune Hibiscus plants. I have two in pots, this is their second season and they have not done well just a few flowers this year, none last year. What kind of compost should I use to replant them.

  • I've just purchased two but desperate to find their place in the garden image I never even considered pots thought they were a garden plant so perhaps that's why your not having much of floral display ( then again what do I know imageimage)

  • Assuming you are growing hardy hibiscus, then plant them in the ground in full sun, at least 6 hours worth. Then prune them in the spring - the flowers grow on the same year's growth so don't be shy. If you are growing the tender ones, then move them into a sheltered spot, say a covered porch (needs to be more than 4 degrees), and repot them in the spring, and prune as before. I grow both sorts, and this works for me. They are such beautiful flowers, it is definitely worth the effort. Good luck. 

  • They are H. Oiseau blue so I am looking forward to the flowering  Thanks Catherine that guides me to the perfect spot image

  • I hope so, Primrose, it was trial, error and deaths (of the poor wee plants) that got me there. image

    Thank you all for your advice. I will see how they get on in the spring.

  • I agree with Catherine Whitehead.  I have many hardy hibiscus and they are all in the ground, they love sun, give them a sunny spot and they'll flower all summer, my favourites are the blues, single and double flowers.  Good luck and enjoy their beauty.

    The hardy ones - hybiscus syriacus types - are deciduous and often don't get their new leaves again until June in may garden if we've had a hard winter.   This year it was early May.

    Hibiscus rosa-siniensis is from tropical China and not frost tolerant at all so, whilst it may enjoy a sunny spot outdoors in summer, it needs to be brought in once temperatures cool and protected till the last frosts are well past in May.

  • We are on the subject of hibiscus, I am sure what MILs stands for.  Yes, hibiscus do shed their leaves, and remain barren until Spring.
