Tuber Sprouting
2-3 weeksTubers develop eyes and small sprouts emerge from the planted tuber.
Plant tubers in spring after last frost when soil reaches 60°F. Water sparingly until growth is visible. Ensure tubers are not rotting due to excessive moisture.
Vegetative Growth
4-6 weeksPlants establish stems and foliage, growing 12-24 inches tall with compound leaves.
Provide consistent moisture and full sun. Pinch back stem tips when plants reach 12 inches to encourage bushier growth and more blooms. Stake or cage tall varieties.
Budding & Early Flowering
2-3 weeksFlower buds form at stem tips; the first large blooms appear with characteristic peony-like form.
Deadhead spent blooms to encourage continuous flowering. Provide supplemental feeding with phosphorus-rich fertilizer. Water consistently; dry soil reduces bloom quality.
Peak Flowering
6-8 weeksAbundant large, full blooms with multiple petal layers cover the plant in vibrant colors.
Harvest blooms in early morning when buds are just opening for best vase life. Continue deadheading. Monitor for pests and diseases during this peak stage.
Fall Senescence & Dormancy
4-6 weeksFlowering slows as temperatures cool; foliage yellows and dies back after first frost.
In zones 2-7, dig tubers after first frost, cure and store in cool, dry conditions. In zones 8-10, cut foliage to ground level; tubers may remain in soil if well-drained.
