Seedling
3-4 weeksTiny seedlings with thread-like first true leaves emerge within 7-14 days. Plants remain low and delicate.
Keep soil lightly moist but not waterlogged. Provide bright light. Thin seedlings to prevent crowding.
Vegetative Growth
6-8 weeks (first year) or 4-6 weeks (subsequent years)Young plants develop the characteristic feathery, finely divided foliage. Compact mounding form begins to establish.
Water moderately. Do not fertilize heavily; this encourages leafy growth at expense of flowers. Pinch tips once to encourage bushiness.
Budding & Early Flowering
2-3 weeksFlower buds form at stem tips, appearing as tight, clustered heads. First flowers begin opening in shades of red or pink.
Maintain consistent but not excessive watering. Deadhead spent blooms to encourage continuous flowering. Stake if needed in windy locations.
Peak Flowering
6-10 weeks (early summer to mid-fall)Flat-topped flower clusters (corymbs) are fully open, displaying vivid red to deep pink colors. Dense blooming covers the foliage.
Deadhead regularly to extend bloom period through fall. Reduce watering as needed; do not overwater. Watch for powdery mildew in humid conditions.
Seed Set & Decline
4-6 weeks into fall and winter dormancyIf not deadheaded, flowers fade and transition to dried seed heads. Foliage may become less vibrant as temperatures cool.
Leave some flowers to set seed for wildlife and winter interest, or deadhead completely for continuous summer bloom. Reduce watering in fall.

Harvest Tips
Achillea Heidi is grown primarily as an ornamental flower rather than a harvest crop. For cut flowers, harvest stems in the morning when flowers are fully open but not yet fading. Deadhead spent blooms regularly to encourage continuous flowering and maintain plant shape. Leave some flower heads in late summer/fall for seed set and wildlife food. Dried flowers can be harvested by cutting entire stems and hanging them upside-down in a dry, well-ventilated area.
