Garden Q&A: Why have my camellia plants never flowered?

Whether you're a gardening beginner or expert, Irish Examiner columnist Peter Dowdall has the answer to your questions

Camellias set their flower buds in late summer and autumn for blooming in the following spring.

I have two camellia plants, nearly three years old. Neither of them has flowered, ever. l changed the soil hoping that they would flower this year but nothing. Can you advise me on this please?
