Does anyone know why my arum lillies will not flower?

They have not flowered since I got them three years ago. They are in full sun and I keep them well watered.



might be the full sun that's the problem - Arum like a bit of shade and damp soil.

Hi Mims

I have put a newer one in a pot that has no draining so always a bit damp (and pongy) in shade and no sign of life yet.!

Arum creticum is sweetly scented, but the others do stink... You could throw a bit of sulphate of potash round it (this is good for flower formation) and see if it helps.

Thanks Mims - although I think its probably more the soggy earth than the plant!

Nics all plants need drainage even if they like damp soil... Arum's like semi-shade but do not particularly need moist ground, ours are under a big ash tree. I would suggest you move that this autumn you move the ones in the ground out of full sun and also repot the one in a pot into a pot with drainage holes

Brilliant - thanks

Oh yes, indeed. No drainage and the plant will drown (if it doesn't rot first, lol).
