My tiger lilies won’t bloom

My tiger lilies won’t bloom

My boyfriend got me a pot of tiger lilies a month ago. Initially, they were in full bloom, but after the blooms fell off, they wouldn't bloom again. Now some of the bottom leaves are drying up. What's up? How can I get the plant to bloom again?
