Germination & Seedling
2-3 weeksTiny seedlings emerge with narrow cotyledons and first true leaves appearing. Seeds are very small and require light to germinate.
Keep soil consistently moist but not waterlogged. Provide warmth (60-70°F) and light for germination. Thin seedlings to 18 inches apart after true leaves emerge.
Vegetative Growth
8-12 weeksPlant develops bushy foliage with narrow, lance-like leaves on branching stems. Height increases gradually with no visible flower buds yet.
Water regularly to maintain moist soil. Pinch back stems in early summer to encourage bushier growth and more flower production. Apply balanced fertilizer monthly. Mulch to conserve moisture.
Budding & Bloom Initiation
3-4 weeksSmall button-like flower buds form at branch tips. Buds transition from green to showing color at the yellow or red sepals.
Continue consistent watering. Reduce nitrogen fertilizer to encourage more blooms over foliage. Support tall varieties with stakes if needed. Remove any dead leaves.
Flowering
6-10 weeksDaisy-like flowers with prominent yellow, red, or orange petals and distinctive rounded button centers open sequentially on each stem. Blooms continue for 6-8 weeks.
Deadhead spent flowers to extend bloom period and promote more flowering. Water consistently. Stake taller varieties (3-4 feet). Cut flowers last 7-10 days in a vase.
Seed Set & Dormancy
4-6 weeks until frostAfter final blooms fade, flower centers develop seed heads. Foliage gradually yellows and withers as plant enters dormancy in fall.
Allow some flowers to remain for seed development and winter bird food. Cut back stems to 4-6 inches after hard frost. Leave seed heads through winter for wildlife and ornamental interest. Do not fertilize.

Harvest Tips
Cut flowers in early morning when fully open but fresh. Harvest stems just above a leaf node. For seed heads, allow flowers to remain on plant until centers brown and dry completely (late fall), then cut and store in paper bags for seed collection. Deadhead regularly for continuous blooming throughout the season.
