Why Tulips Produce Leaves But No Flowers

Most hybrid tulips bloom reliably for only a year or two—hence Dutch growers replant annually. Only species (botanical) tulips return perennially. Poor flowering can also stem from how the bulbs were treated the previous year.

After blooming, leave foliage intact until it fully yellows and dies back; this recharges the bulb for next year. Deadhead spent flowers to prevent seed formation, which diverts energy from bulb development.
