Water regularly, provide bright light, protect from strong wind; avoid fertilizing heavily to prevent tender growth
Vegetative Growth
2-4 monthsPlant develops bushy foliage and branching structure; leaf pairs are opposite and elongated
Prune to shape and encourage branching; begin light fertilizing with balanced formula; maintain consistent moisture
Budding
2-3 weeksSmall flower buds form in terminal clusters at branch tips; buds are tight and compact
Maintain steady watering and warmth; increase phosphorus fertilizer to promote blooming; avoid overhead watering to protect buds
Flowering
4-8 weeks per cycle; multiple cycles in warm climatesClusters of star-shaped flowers open in vibrant colors; flowers attract pollinators; blooms persist for weeks
Continue regular watering and fertilizing; deadhead spent blooms to encourage more flowers; maintain 70°F+ temperatures for continuous blooming
Rest/Dormancy
2-4 months (winter in subtropical zones)In cooler seasons, flowering slows significantly; plant may lose some foliage in temperatures below 60°F
Reduce watering and fertilizing; protect from frost and cold winds; maintain minimum temperature of 50°F; prune to shape for next season

Harvest Tips
Ixora is grown for ornamental flowers rather than harvest. Deadhead spent flower clusters by pinching or cutting just below the spent blooms to encourage continuous flowering. Cut flower sprays can be used in arrangements; harvest in early morning when flowers are fully hydrated. Prune in late winter or early spring to shape plant and remove dead or crossing branches.
