Growth Stages

1

Dormancy & Planting

Variable; dormancy lasts 8-12 weeks before sprouting

Dormant bulbs are planted in fall (September-November) for spring emergence or in early spring for summer blooms.

Choose firm, disease-free bulbs. Ensure excellent drainage by adding sand or perlite to planting holes. Plant with pointed end up. Water lightly after planting.

2

Sprouting & Growth

3-4 weeks

Green shoots emerge and elongate, developing 6-8 linear leaves along the stem. Roots establish and the plant grows 2-4 inches weekly.

Apply mulch around base to retain moisture and regulate soil temperature. Stake tall varieties early. Water deeply once weekly. Remove any fallen debris from foliage.

3

Budding

2-3 weeks

Flower buds appear at the stem tip and along the upper stem, swelling noticeably. Buds show the golden-yellow color and begin to elongate.

Continue deep watering. Apply balanced fertilizer (lower nitrogen, higher phosphorus & potassium). Remove lower leaves if they yellow. Ensure adequate airflow.

4

Blooming

2-4 weeks (individual flowers last 5-7 days)

Large trumpet flowers open sequentially, displaying golden-yellow petals with darker spotting, recurved margins, and prominent stamens. Flowers emit strong sweet fragrance.

Enjoy the blooms; deadhead spent flowers to encourage further blooms (leave stem & leaves). Support heavy-flowered stems with stakes. Reduce watering slightly if rainfall is adequate.

5

Decline & Dormancy

6-8 weeks

Petals fade and fall; seed pods develop if flowers were not deadheaded. Foliage gradually yellows and senescence begins.

Allow foliage to remain until completely yellow (6-8 weeks post-bloom); this rebuilds bulb energy reserves. Reduce watering gradually. Do not remove foliage until fully dormant. Apply low-nitrogen fertilizer to support bulb development.

Common Pests

  • Hand-pick beetles and larvae daily; use neem oil or spinosad spray. Remove debris where beetles overwinter. Apply insecticidal soap for severe infestations.

  • Spray with water to dislodge; use insecticidal soap or neem oil. Encourage beneficial insects like ladybugs.

  • Increase humidity by misting foliage; use miticide if severe. Remove heavily infested leaves.

Harvest Tips

Cut stems for arrangements in early morning when flowers are just opening or still in bud stage. Remove lower leaves that would be submerged in water. Cut at an angle with sharp shears.
