Growth Stages

Dormancy/Planting

Planting occurs once in spring

Corms are dormant and ready for planting; they appear as hard, rounded bulb-like structures.

Plant corms pointed-end up in spring after last frost. Choose a location with excellent drainage. Space 4-6 inches apart.

Sprouting & Vegetative Growth

3-4 weeks

Shoots emerge from the soil and develop sword-like green foliage. Plant grows rapidly, developing 6-8 leaves.

Keep soil consistently moist. Apply balanced fertilizer every 2-3 weeks. Remove weeds promptly. Stake plants if necessary for wind protection.

Bud Formation & Flowering

2-4 weeks

Flower spike emerges from the center of the plant. Buds form along the spike and gradually open from bottom to top.

Maintain consistent moisture and apply higher potassium fertilizer to promote blooming. Remove any diseased foliage. Deadhead spent flowers to encourage longer blooming.

Peak Bloom

2-3 weeks

Flowers are fully open along the spike, displaying the characteristic red petals with white throat markings.

Cut spikes in the morning when 1-2 bottom flowers open for cut arrangements. Continue deadheading. Enjoy the blooms.

Seed Development & Decline

3-4 weeks

Flowers fade and fall; seed pods may develop. Foliage begins to yellow. Corm enlarges underground for next season's growth.

Remove spent flower spikes to redirect energy to corm development. Continue watering and fertilizing with lower nitrogen formula. Allow foliage to yellow naturally before cutting back.

Harvest Tips

Cut spikes in early morning when the first 1-2 florets are open; use a sharp knife and cut at least one-third of the stem length from the base; place immediately in cool water with floral preservative. For dried arrangements, cut when flowers reach full color and hang upside down in a dark, well-ventilated space. Leave at least 4 leaves on the plant to feed the corm for next season.
