Propagation
1-2 weeksSoft stem cuttings develop roots in water or moist soil, typically showing tiny white root initials
Take 3-4 inch cuttings from healthy stems; place in water or moist perlite; maintain humidity and bright indirect light; roots appear in 1-2 weeks
Establishment
2-3 weeksYoung rooted cuttings develop their first true leaves and establish a compact root system in soil
Pot rooted cuttings into 2-3 inch pots with potting mix; maintain consistent moisture; keep in bright indirect light; pinch growing tips to encourage bushiness
Vegetative Growth
Ongoing, 4-8 weeks to mature sizePlant grows rapidly, producing new leaves and stems; trailing varieties develop long runners while upright types become fuller
Provide bright indirect light to maintain variegation; water when top soil feels slightly dry; feed with diluted balanced fertilizer every 2-3 weeks; pinch tips regularly for bushier habit
Flowering
Intermittent, 2-4 weeks when triggeredSmall, delicate flowers appear in terminal spikes (typically purple, pink, or white depending on variety); non-essential to foliage display
Flowering is optional; pinch off flower spikes to direct energy to foliage if desired; flowers are attractive but short-lived
Maintenance
Several months to years with proper careMature plant maintains its size and appearance with regular care; may become leggy if light is insufficient
Prune back leggy growth by 1/3 to refresh plant; continue regular watering and feeding schedule; repot to larger container annually or as needed

Harvest Tips
Plectranthus is grown for foliage rather than harvest. Pinch off growing tips regularly (every 4-6 weeks) to encourage bushier growth and prevent legginess. Remove lower leaves that become yellowed or damaged. Some varieties can be used as culinary herbs; harvest fresh leaves as needed by pinching stems. For fragrant or culinary types, harvest in morning after dew dries for best aroma.
