Establishment
First yearYoung vine with emerging compound leaves and delicate tendrils beginning to climb and twine
Water regularly to establish deep root system. Provide sturdy support structure. Remove any damaged growth. Mulch around base to retain moisture
Vegetative Growth
Year 1-2Vigorous expansion of foliage with five-leaflet leaves covering support structure; plant establishes framework
Train vine onto support as desired. Prune to direct growth and control spread. Continue consistent watering. Apply balanced fertilizer in spring
Flowering
2-4 weeks, typically March-AprilDelicate, small purple to violet flowers appear in early spring (March-April in most zones), arranged in drooping clusters with distinctive vanilla fragrance
Avoid heavy pruning during flowering period. Ensure adequate sunlight for maximum blooms. Do not apply excess nitrogen fertilizer as it encourages foliage over flowers
Fruiting
6-8 weeks, July-SeptemberAfter successful pollination, distinctive elongated pod-like fruits develop, turning from green to deep purple as they mature
Maintain consistent moisture for optimal fruit development. Multiple plants or cross-pollination increases fruit set. Protect fruits from excessive heat stress
Dormancy/Harvest
October-FebruaryFoliage may drop or become sparse in winter depending on zone and variety; vine enters semi-dormant period
Harvest fruits when fully purple and slightly soft. Prune vine during dormancy to shape and control growth. Minimal watering needed in winter in colder zones

Harvest Tips
Pick fruit in late summer to early fall (August-September) when pods are fully purple and yield slightly to pressure. Fruits are ripe and ready to eat fresh when they have a deep purple color and soft texture. Cut or gently twist pods from vine. Fruits can be eaten fresh, seeds and all, though some people prefer to scoop out and discard the bitter seeds. Store fresh fruits in refrigerator for up to one week
