How to Grow Tulip — Tulipa

Sharing is caring!

Tulips are classic spring-blooming bulbs prized for their showy flowers that come in a wide range of colors–nearly all colors except true blue. Many tulips are bicolored. the most familiar tulips have elongated cup-shaped blooms, but there are also tulips with bowl-shaped blossoms and double-flowered cultivars. There are goblet- and star-shaped tulip blooms as well.

Tulip flowers are borne on slender, upright, usually unbranched stems reaching upwards from basal linear and strap-shaped leaves. Tulips grow from plump teardrop-shaped, tunicate bulbs.

There are about 100 species of tulips and hundreds of named cultivars. All are organized into 15 divisions based on flower shape and origin. Grower catalogs use the divisions to organize their offerings. Roughly, tulips are divided into two groups, species tulips, and hybrid tulips.

The smaller species of tulips are best used in informal beds, borders, and rock gardens. Taller, larger hybrid tulips are dramatic and good choices for formal, massed beds, and in clumps in the flower garden or shrub border. Tulips make excellent cut flowers as well.

While all tulips bloom well the first year, many decline in the following years, especially some hybrids. Choose tulips from the following division for best performance: Darwin Hybrid Tulips, Triumph Tulips, Kaufmanniana Tulips, Fosteriana Tulips, and Greigii Tulips. Species of tulips that are good performers are Tulipa batalini, T. humilis, T. saxatilis, and T. tarda. (See below)

When to plant Tulips

  • Plant tulips in mid-autumn in Zones 3-7; work compost and bulb fertilizer into the soil.
  • In Zones 8-11, place bulbs in the refrigerator for 6 to 10 weeks before planting outdoors.
  • Tulips can be forced indoors for winter bloom pot bulbs in fall, place the pots in a refrigerator or outdoors if temperatures are cooler than 40°F (4.4°C) for four to six weeks, and then bring them indoors to grow and bloom.

Spacing and planting Tulips

  • Space tulips 4 to 10 inches (10-25cm) apart.
  • Plant tulips 4 to 6 inches (10-15cm) deep.
  • For best effect, plant tulips in groups, use 6 bulbs of smaller tulips and 3 or more bulbs of larger tulips in each group.

How to water and feed Tulips

  • Tulips need ample water during growth and bloom and moderate water after.
  • Add bonemeal or an all-purpose fertilizer to planting holes when planting bulbs.
  • Fertilize tulips with an all-purpose fertilizer in spring when shoots begin to emerge.

Tulips care

  • Mulch tulips for winter protection in Zones 3-4; cover bulbs with chopped leaves. In very cold winter regions, mulch with 6 inches of evergreen boughs. Remove the mulch when leaves appear in early spring.
  • Remove flowers as soon as they fade to prevent seed set and encourage bulb development.
  • In spring, after blooming, allow foliage to die back before removing it.
  • Tulips can be forced indoors. Seed Planting above.

Growing Tulips as houseplants

  • Tulips can be purchased in bloom or bulbs can be forced into bloom at home.
  • To force your own tulips, pot the bulbs in fall in a well-drained, soilless medium and place five to six bulbs in a 6-inch pot.
  • Plant the bulbs with the flat side against the rim of the pot.
  • The tip of the bulb should be just below the medium.
  • Place the pot outdoors, either protected in a cold frame or buried in the ground.
  • If temperatures do not drop below 40°F, the pot and bulbs must be refrigerated. Chill the bulbs for 12 to 16 weeks or until the bulbs have 2 to 3 inches of top growth.
  • Move the pot to a room where the temperature is cool, light is direct and humidity is medium to high.
  • Keep the medium evenly moist.
  • Fertilizing is not necessary.
  • Tall varieties may be staked.
  • After the tulips have finished blooming they can be planted outdoors where they may bloom the following year.

Tulip common problems

  • Root and bulb rots are common in wet or poorly drained soil.
  • Gray mold, slugs, snails, and aphids can be a problem.
  • To protect bulbs from rodents that will dig them up, plant bulbs inside a wire mesh cage or place a wire mesh on top of the planting beds.

Tulip propagation

  • Sow seeds of species in autumn.
  • Separate offsets of species and cultivars after lifting in summer, replant, and grow on.
  • Divide species tulips every two to three years when flowers start to become smaller; if flowers become very small, discard the bulbs.
