We purchased several nice pots of Calla Lilies and would like to know when & how to propagate them. Thank you so much!
When the leaves die down in autumn, tip out your pots (not at the same time unless you bought the same colour twice...).
There will be these lumpish which-side-is-up bulby-looking things, browny-cream. And there will be little ones. Pot these up separately from the bigger ones.
Each lump has several growing points on the top, like the eyes on a potato, and the roots come from the top, too.
Good drainage and good compost-y planting medium. Wind shelter and around six hours of sun.
Depending on your zone or micro-climate, you can leave them in the ground over winter.
Some hybrids can be slow to multiply. If not much has happened underground this season, replant anyway.
If they set seed you can plant them out quite thickly, then pot on the little tubers for the following season. Hybrids generally won't come true from seed but you could get some interesting results.
Thanks a lot !!! :-D
How do we recognize if seeds have formed for the calla lily? And can we plant them as soon as we see them? Or allow them to dry for months prior to planting? If a flower is "spent", does that mean it will automatically form seeds but the plant help. Thank you so much!!!
