Hello I am in North Vancouver BC. I have a couple of Japanese Spider Lily bulbs that are struggling. They should bloom around the end of September and then produce leaves. They have been in the ground for about 20 months so we are coming up to winter number two. No flowers and at the moment the leaves are only about an inch long. So they don't seem very happy, but they are still in the land of the living. Do they take a long time to get established? Is North Van too cold for them? Should I dig them up and perhaps put them in a pot and treat them as indoor plants? I loved these flowers when I saw them in Japan so I really want them blossom and flourish (plus the bulbs were quite expensive...). Suggestions welcome!
