After the leaves are dead you can cut them back and just leave the bulbs until next year when many will bloom again. High quality bulbs should come back for about 3 years, but they do get weaker year after year. I would like to receive my spring bloomers (like tulips, daffodils, etc) in spring/summer.
1 Deadhead tulips after flowering. 2  Allow the foliage to yellow for about 6 weeks after flowering before removing it. 3  The bulbs of Species tulips may be left in the ground for several years; others may be lifted annually, once the leaves have died down, and ripened in a warm, dry place. Plant tulip bulbs in the fall, 6 to 8 weeks before a hard frost is expected and when soils are below 60 degrees F. (See our frost charts.) This timing ranges from early autumn (Zone 4) to late autumn (warmer zones).
