Growth Stages

1

Tuber Sprouting

2-3 weeks

Tuber is planted and begins producing small sprouts and root development; minimal visible growth above soil.

Plant after last frost when soil is warm (60°F+). Keep soil consistently moist. Provide stakes or support structure early. Avoid over-watering before sprouting.

2

Vegetative Growth

4-6 weeks

Leafy shoots emerge and grow rapidly; plant develops multiple stems and a bushy shape with dark green foliage.

Pinch out the top 2-3 inches when plant reaches 12-18 inches tall to encourage branching. Apply balanced fertilizer every 2 weeks. Maintain consistent moisture and mulch to retain water.

3

Bud Formation

2-3 weeks

Flower buds appear at the stem tips; plant reaches full height and continues to thicken with additional lateral shoots.

Switch to higher-phosphorus fertilizer to encourage blooming. Increase watering as bud development demands more moisture. Stake heavily to support large flower heads.

4

Flowering

8-12 weeks (until frost)

Large, full decorative blooms open with soft peachy-apricot coloring and full, ruffled petals. Multiple flowers are produced continuously.

Deadhead spent flowers regularly to encourage continuous blooming. Harvest flowers in early morning for cut arrangements. Monitor for pests and diseases. Continue regular watering and feeding.

5

Tuber Dormancy & Storage

4-6 months

Foliage blackens after first frost; underground tubers enter dormancy for winter rest.

After frost, cut back foliage to 4-6 inches. Dig tubers carefully, allow to dry for several days, dust with fungicide, and store in cool (50-60°F), dark, dry location. Check periodically for rot.

Harvest Tips

Cut flowers in early morning when stems are fully hydrated, using sharp pruners. Cut long stems (12+ inches) just above a leaf node. Remove lower foliage below the waterline in vases. Flowers last 7-14 days in a vase with regular water changes and floral preservative. For longest vase life, harvest when outer petals are just fully open. Continuous deadheading of spent blooms in the garden encourages more flower production.
