Establishment
4-8 weeksYoung vine with tender green stems and small ovate leaves. Plant is adjusting to new location.
Water regularly to keep soil moist. Provide support structure or trellis. Protect from strong winds. Fertilize lightly every 2-3 weeks.
Vegetative Growth
2-4 monthsPlant develops longer stems, fuller foliage, and becomes more established. Leaves remain bright green and vigorous.
Prune lightly to encourage branching and bushier growth. Continue regular watering and monthly feeding. Ensure good air circulation.
Pre-flowering
4-6 weeksStems thicken, foliage becomes denser, and small flower buds begin forming at leaf axils in late autumn.
Reduce nitrogen fertilizer, increase phosphorus to promote flowering. Provide cooler temperatures (50-60°F) for 4-6 weeks to trigger blooming. Maintain consistent moisture.
Flowering
6-12 weeksAbundant clusters of star-shaped white flowers with pink buds cover the vine. Flowers open progressively and release intense sweet fragrance, especially in evening.
Do not prune during flowering. Deadhead spent flowers to encourage more blooms. Maintain humidity. Continue regular watering but reduce feeding.
Post-flowering & Rest
4-8 weeksFlowers fade, foliage remains evergreen. Plant enters a quieter growth period preparing for next flowering cycle.
Prune back after flowering to shape plant and remove spent growth. Reduce watering slightly. Lower nitrogen fertilizer. Maintain warmth.
