Seedling
2-3 weeksTiny seedlings with first true leaves appearing; very delicate with thin stems
Keep soil moist but not soggy; provide bright indirect light; maintain 70-75°F temperature; provide gentle air circulation to prevent damping-off disease
Vegetative Growth
3-5 weeksPlant develops branching stems and oval-shaped, wrinkled leaves with hairy texture; compact bushy form emerging
Pinch growing tips when 3-4 inches tall to encourage bushiness; gradually increase light exposure; fertilize every 2 weeks with balanced fertilizer; maintain consistent moisture
Pre-flowering
2-3 weeksPlant becomes fuller with more developed foliage; first flower buds begin forming at stem tips
Continue pinching side shoots until buds appear to maximize flowering; switch to higher phosphorus fertilizer to promote blooms; ensure full sun exposure
Flowering
6-12 weeks or until frostAbundant tight clusters of small purple flowers appear at branch tips; intensely fragrant blooms attract pollinators
Deadhead spent flower clusters regularly to encourage continuous blooming; maintain consistent watering; apply balanced fertilizer every 3 weeks; provide support if needed
Decline/Dormancy
Variable by climateFlowering slows as temperatures drop and day length decreases; foliage may yellow slightly
Reduce watering frequency; stop fertilizing; in zones 9-10, cut back by half and bring indoors or mulch heavily; in warmer zones, plant may flower year-round
