Seedling
2-3 weeksTiny seedlings with cotyledons emerge and develop their first true leaves with characteristic fine, feathery texture
Keep soil lightly moist but not wet. Provide bright light. Thin seedlings to prevent crowding. Do not bury seeds; they need light to germinate.
Vegetative Growth
4-6 weeksPlant develops bushy rosette of finely divided, fern-like foliage in green tones. Multiple stems emerge from the base.
Water moderately during establishment. Once roots are deep, reduce watering. Pinch tips to encourage bushier growth if desired. No fertilizer needed; prefers lean soil.
Budding & Early Bloom
2-3 weeksFlowering stems elongate and develop tight clusters of unopened buds at stem tips, gradually showing red-orange coloring
Maintain consistent (not excessive) watering. Deadhead spent flowers to encourage continuous blooming. Stake tall stems if needed in windy locations.
Peak Flowering
6-8 weeks or more with deadheadingFlat-topped flower clusters (corymbs) open fully, displaying vibrant red-orange blooms that attract butterflies and bees. Flowers mature from the center outward.
Deadhead regularly to extend bloom season through fall. Refrain from fertilizing, which promotes foliage over flowers. Cut stems for arrangements as desired.
Senescence & Dormancy
Fall into winter; 3-4 monthsBlooms fade and dry on the plant; foliage may turn bronzy or reddish in cool fall temperatures. Plant gradually enters dormancy in winter.
Allow spent flower heads to remain for winter interest and wildlife food. Cut back old growth to 2-3 inches in early spring. No supplemental water needed unless drought extends into dormancy.

Harvest Tips
Cut flowers in early morning after dew dries, when blooms are fully open but still vibrant. Cut stems at least 6 inches long just above a leaf node to encourage bushier growth and more blooms. Yarrow flowers dry beautifully for arrangements—hang bundles upside down in a cool, dark location. Fresh-cut flowers last 1-2 weeks in water; dried flowers last months or years.
