That is what I thought, just worried about the light aspect! Thanks 4P Keith I wouldn't worry about that Keith, as the growing tips/buds will still be in the dark in the compost. I eventually cheated and brought the pot inside on the kitchen window sill. It's coming up now so no more worries. |

Green Goddess is flowering it's socks off but the rest are very disappointing.
Why?

Thanks The witch. 2 of your links re Crowborough which is OK but all mine are different coloured varieties and I do exactly what it says on the tin. What about specialist nurseries? |

From my Reader's Digest New Encyclopedia of Garden Plants and Flowers:- Cultivation:
Plant the rhizomes of Z. aethiopica and its cultivars 10cm (4in) and about 40cm (16in) apart in moist or wet, fertile soil. If treating s an aqutic plant, place in a planting basket at a depth of 15-30cm (6-12in.)
Plant Z. elliottiana and Z. rehmannii in 20-25cm (8-10in) pots, in John Innes No. 2 or 3 or in a moist, peat based compost. Keep in a greenhouse over winter, then in late spring or early summer plant them outside or place the pots outside. Feed regularly and reduce watering in late summer before bringing the plants inside once more. Are your plants very young Mick - it's still very early in the season to decide that they are failures.  Nope. Had them for years. I'm trying potbound now. Perhaps I should repot and just keep the big corms. I've got 2 editions of the RD book but mainly use the early one. |

Not repotted since 2006 but fed regularly.

I've trwled through a fair number of sites.
It seems to be:-
rich soil
full sun
moist
Tomato fertiliser
Large quality corms about 4" deep and 12" apart.
Commercial growers suggest dipping in gibberellin to increase flowering.
I think I may dump most of mine at the end of summer if they don't perform and buy from a specialist for next year.

My Zantedescia are just poking their heads up from the compost Mick, as are my Cannas, you seem to be weeks ahead of us in Birmingham! The white Arum in the pond is already flowering though...perhaps the others have been too dry? : |

As SL says, mine in the pond is onto it's second flower, but the one I have in a pot, purplish one is doing well, but no flowers yet, though I have just re potted it a few days ago. What's gibberellin, some sort of growth hormone, I suppose? Edit. Should have just looked it up, shouldn't I? It mentions sex in that article!!  |
