Guide vines along support structure. Prune to encourage branching and fuller growth. Continue regular fertilizing during growing season.
Pre-flowering
1-2 monthsVine reaches mature size; leaf production continues; flower buds begin forming at branch tips
Reduce nitrogen fertilizer, increase phosphorus to promote flowering. Maintain consistent moisture.
Flowering
3-5 months (typically spring through summer)Spectacular clusters of small purple-blue flowers with white centers appear at branch terminals; blooms last several weeks
Continue regular watering and feeding. Deadhead spent flowers to encourage more blooms. Provide afternoon shade in intense heat.
Fruiting & Dormancy
2-4 monthsPapery, winged, star-like fruits develop and persist on vine; foliage may thin in winter; reduced flowering
