Bought a yellow arum lily bulb a few years ago, the first year it had one flower on it the next two years it had none but we did have hard winters, so I dug it up and put it in a pot in the conservatory now its all green leaves but no flowers, i water and feed it, is there anyting else I can do.
I have 2 in the garden that both usually flower. At the moment both are still all leaves, I'm hoping improved warmer weather will bring them to flower later this summer.
