Seedling
2-3 weeksTiny seedlings emerge with fine, thread-like cotyledons. Feathery foliage begins to develop early.
Keep soil lightly moist but not wet. Provide bright light and good air circulation to prevent damping off. Thin seedlings to proper spacing.
Vegetative Growth
4-8 weeks (first season) or emerges in spring in established plantsPlant develops dense, finely divided foliage with a feathery appearance. No flowers yet; focus is on root and leaf development.
Water moderately during dry spells. Mulch lightly to retain moisture and suppress weeds. Pinch back if leggy to encourage bushier growth.
Budding & Flowering
6-12 weeks (June-September)Flower buds form at stem tips, then open into flat-topped clusters (umbels) of tiny, densely packed deep red to orange-red flowers.
Deadhead spent flowers regularly to encourage continuous bloom. Reduce watering slightly as flowers appear. Stake tall varieties if needed in windy locations.
Peak Bloom
4-8 weeks (peak period within flowering stage)Clusters are fully developed with vibrant deep red coloring. Flowers attract butterflies, bees, and other pollinators.
Deadhead regularly to extend blooming period. Fertilize monthly with balanced or low-nitrogen fertilizer to maintain vigor.
Seed Set & Decline
4-6 weeks into fallIf not deadheaded, flowers dry and develop seeds in tan-brown clusters. Foliage may fade in heat or drought.
Leave some seed heads for wildlife and natural reseeding, or remove for tidiness. Cut back dead growth in fall or early spring. Divide overcrowded plants.

Harvest Tips
Achillea is primarily grown for ornamental flowers and foliage rather than harvesting for consumption. Cut flowers can be harvested when clusters are fully open for fresh or dried arrangements. For drying, cut stems just as flowers fully open and hang upside down in a dark, airy location for 2-3 weeks. Deadhead spent flowers regularly throughout summer to encourage continuous blooming and maintain plant shape. Allow some seed heads to remain for fall interest and self-seeding.
