I have a Crinum in a 14 inch x 14 inch pot. It has been in the pot for 3 years but never flowered, although it has plenty of healthy leaves. It is situated on a stone patio and is in the sun from about 9am till 4pm. Can you tell me why it does not flower please?
When purchasing Crinum Lily bulbs you should look for the words, 'bloom ready'.
Even you purchase these mature type bulbs it can take 2 to 3 years for the newly planted bulbs to take root and settle in.

My crinum lily bulbs seem very crowded since they have multiplied so much. Would I get more flowers if I thin out some of the bulbs
Plant Woman,
Yes, giving your crinums more space and some additional nutrients usually does improve flowering. See the last tip here: https://www.leafari.com/crinum-planting-guide.html
Good afternoon, Can you please tell me how crinum lilies do in windy conditions? I am busy establishing a shady garden under an avenue of pine trees, with clivias, veltheimias, Mona Lavender plectranthuses, and would like to add my crinums to the group. We are living quite near the sea and are getting some heavy sea winds now and then. Would you recommend putting a few scadoxuses to the mix too? Thank you so much! Kind regards, Renée in Mossel Bay, South Africa
A Crinum Lily can reach 3 to 5 feet in height when mature. This height plant could be very vulnerable to high wind conditions.
Blood Lily may be a better choice at a mature height of around 2 feet.

What should I do when my lily is finished blooming?
Yes, you can prune back the spent flower stems.

How do I separate these lilies?
They propagate similarly to many flowering bulbs. Just make sure to do it in the winter. Here is an article that will explain more: http://www.gardeningsolutions.ifas.ufl.edu/giam/plants_and_grasses/flowering_plants/crinums.html
I am remodeling an area of my garden here in central North Carolina(zone 7b) and have dug up two Crinum, 'Ellen Bosanquet' and 'Mrs. James Hendry', which I'd like to share with friends. There are at least 5 large (4"+ diameter) bulbs of each and many offsets as they have been in a moist, well drained section against the brick wall of the house with morning sun for 6+ years. I assume the bulbs should be replanted ASAP. Should the roots be kept moist until replanted? Fertilized when replanted? Any special tips or advice on transplanting these bulbs will be appreciated.
Yes, Crinum bulbs will do best if they are replanted right away. However, they can be stored for up to a year in a cool but not frozen, ventilated, dark area.
To transplant now, you can keep the roots moist for a few days with some damp towels or newspaper, but they will also be fine if you don't. Make sure the roots are left on the bulb and handled gently. This article will show you how to plant the bulb:

I have a cranium lily in a pot. The leaves are variegated lighter green and white. It is about 32"tall and flowers periodically. A rust colored fungus(?) has developed at the base of some leaves and has moved outward about a third of the way to the leaf end. Beyond a poor appearance cannot determine what, if any, damage may be occurring. Will appreciate any information. J.Cannon Ponce Inlet, Fl.
Rust fungus is a difficult issue to resolve, after it has set in.
Removing the diseased leaves and disposing of is the first step.
Continual treatment with Neem Oil is a treatment that I use in my own garden.
