Seedling
2-3 weeksTiny seedlings emerge with thread-like cotyledons and quickly develop their first true leaves
Provide bright, indirect light. Maintain consistent moisture. Keep temperatures around 65-70°F. Provide good air circulation to prevent damping off.
Vegetative
4-6 weeksYoung plants develop multiple sets of linear, blue-green foliage and form compact mounds without blooming
Pinch growing tips when 3-4 inches tall to encourage bushiness. Ensure full sun for compact growth. Keep soil moist but not soggy. Apply balanced fertilizer every 2-3 weeks.
Flowering
8-12 weeks (can extend with deadheading)Plants become covered with small, fragrant flowers with fringed petals in various colors and patterns
Deadhead spent flowers regularly to extend blooming period. Maintain consistent watering. Apply low-nitrogen fertilizer to encourage flowering over foliage. Watch for pests.
Peak Bloom
4-8 weeksPlant reaches maximum flower production with dense clusters of continuous blooms throughout the canopy
Continue deadheading diligently. Reduce fertilizer to minimal levels if plants become leggy. In hot climates, provide afternoon shade to prevent flower fade.
Decline/End of Season
Variable, typically late summer onwardBlooming slows as temperatures rise or as plants approach their annual life cycle; foliage may look tired
Plants may be removed and composted or cut back for potential regrowth. Collect seeds if desired before removing plants. Plan fall planting for cool-season reprise.

Harvest Tips
For cut flowers, harvest in early morning when stems are fully hydrated. Cut stems at an angle just above a leaf node. Remove lower foliage to extend vase life (typically 7-10 days). Deadhead spent flowers on garden plants throughout the season by pinching off flower heads just below the bloom, which encourages continuous flowering.
