Growing: Tulips

By Ellen Brown

Growing: Tulips
Botanical Name: Tulipa
Life Cycle: perennial
Planting Time: fall
Height: 4" to 30"
Exposure: full sun to light shade
Soil: rich, well-drained soil
Hardiness: zones 3 to 8
Bloom Time: spring
Flower: a variety of brilliant solid and mixed color patterns (except blue); saucer-shaped with 6 petals (except doubles); 400+ cultivars
Foliage: blue-green, smooth, thick, upright leaves with a blade-like shape; 6 to 10 inches long
Propagation: bulbs
Suggested Use: beds, borders, cut flowers, walkways and mass plantings
Growing Hints: Plant bulbs from 4 to 8 inches deep and 4 to 8 inches apart in the fall. Bulbs should be free of mold or black spots and the outer tunic (brown layer) should be intact. If bulbs fail to bloom, they may have been handled or stored improperly before purchasing. For example, bulbs stored above 70ºF may not bloom well-or at all the first year, but may emerge the second year. If you want bulbs to bloom south of zone 8, you'll need to cold treat the bulbs (in the refrigerator) for 4-6 weeks before planting or buy bulbs pre-chilled. Bulbs can be moved or discarded when leaves die back and should thrive in dry soil conditions after flowering.
Interesting Facts: The absence of emerging growth may be an indicator that rodents have made a buffet out of your bulbs. Placing chicken wire over the tops of holes after planting or mixing blood meal in with the dirt used to refill the planting holes will discourage most rodents from snacking on your hard work.
