Dormancy/Leafless
2-4 monthsPlant drops all leaves and becomes dormant during cool winter months (December-March in Northern Hemisphere). Branches appear bare and woody.
Minimize watering to every 3-4 weeks. Stop fertilizing. Move indoors in cold climates or protect from frost. Temperature should stay above 50°F.
Leaf emergence
3-4 weeksNew leaves begin sprouting from branch tips as temperatures warm in spring. Leaves are glossy, elongated, and dark green.
Resume regular watering as growth begins. Increase watering frequency gradually. Begin fertilizing with balanced or bloom-promoting fertilizer every 2-3 weeks.
Vegetative growth
4-8 weeksPlant develops full canopy of leaves and stems elongate. No flowers appear yet; focus is on foliage development.
Maintain consistent moisture (not soggy). Fertilize every 2 weeks with balanced fertilizer or one higher in nitrogen. Prune to shape if desired. Monitor for pests.
Flowering
6-12 weeks or moreClusters of fragrant five-petaled flowers appear at branch tips in colors ranging from red to pink, yellow, cream, and bicolors. Flowers are 2-3 inches across.
Switch to phosphorus-rich fertilizer (higher middle number) to promote blooms. Maintain consistent watering—do not let soil dry completely or flowers may drop. Deadhead spent blooms to encourage more flowers.
Seed pod development (optional)
6-8 weeksIf flowers are pollinated, elongated seed pods develop. Pods mature over weeks and split open to release winged seeds.
Remove seed pods if you prefer the plant to focus energy on more blooms. Allow pods to mature only if you wish to collect seed for propagation.

Harvest Tips
