(Question)
I have two such plants that have not blossomed for several years. How can I get these plants to flower?

Attached below, you will find a link to a previous question regarding Amaryllis care and re-flowering which was answered by the Toronto Master Gardeners some time ago. Your question is a very common one as many people want to save these beautiful flowering bulbs and enjoy them for multiple years.
Good luck.
