Seedling
10-14 daysTiny seedlings emerge with cotyledons and quickly develop narrow linear true leaves
Provide bright light and keep soil moist but not saturated. Thin or transplant when first true leaves appear. Avoid damping off by ensuring good air circulation.
Vegetative Growth
3-4 weeksPlant develops compact, bushy form with dense foliage; no flowers yet
Pinch back growing tips when 4-6 inches tall to encourage branching. Maintain consistent moisture and remove any dead or diseased leaves.
Flowering
6-12 weeks (or longer with deadheading)Abundant small flowers appear in characteristic ruby-red with white or pale pink picotee edges; blooms emerge continuously
Deadhead spent flowers regularly to extend blooming. Fertilize every 2-3 weeks with balanced or slightly higher phosphorus fertilizer. Water at soil level to keep petals dry.
Peak Bloom & Maintenance
4-8 weeks or until frostPlant is fully covered with flowers; may slow slightly in extreme heat but rebounds in cooler weather
Continue deadheading and fertilizing. Cut back by one-third if plant becomes leggy. Provide afternoon shade in zones 8+ during intense summer heat.
Decline/Overwintering
Variable; until first hard freeze or into next growing seasonPlant stops flowering in frost zones 3-4; may survive winter in zones 5-9 with protection or resprout from roots
In cooler zones, plant will die back; collect seeds before frost if desired. In warmer zones, cut back and mulch lightly for potential rebloom next season.

Harvest Tips
Pinch or cut flowers in early morning when stems are turgid for longest vase life (5-7 days). Remove lower leaves that would sit in water. Continue harvesting or deadheading to encourage more blooms. Collect seeds in late summer by allowing a few spent flowers to dry on the plant; harvest papery seed pods and store in cool, dry place.
