Hi Julie, funny you should say that about your Hibiscus, as I have just been reading a letter sent up to my gardening mag. about this - (not you, was it?
The reader asked why her 2 Hibiscus had never flowered, even though they'd been in the ground for about 5 years.
The Experts reply was as follows:
"Failure to flower is quite common with woody plants, it is is often easy to remedy once the cause is known.
How is the leafy growth on them?
Poor leaf growth suggests the plant is growing in the wrong place with the wrong conditions. Moving it will be the best solution.
However, lush leafy growth can be caused by over feeding with high-nitrogen fertilisers, and will be at the expense of the flowers.
If this is the case, you could try6 to redress the balance with a late summer feed of sulphate of potash to help this year's wood to mature and encourage the production of flowers.
Next spring, feed just once with a slow-release general purpose fertiliser.
Another problem could be the light levels.
Hibiscus does best in full sun and a sheltered position.
Plants that need full sun rarely flower to their full potential in shade or even partial shade.
Hibiscus needs a long, hot summer to flower well. In cool summers, or on North and East-facing sites, they may struggle to flower."

So there you go. Perhaps that's some help, Julie?
