Establishment
3-4 weeksYoung vine with emerging shoots and developing root system; foliage is small and tender
Provide consistent moisture and warmth; protect from cold drafts; stake or trellis early; avoid fertilizing immediately after planting
Vegetative Growth
4-6 weeksRapid shoot and leaf development; vines lengthen and climb; foliage becomes fuller and more robust
Provide sturdy support structure; fertilize every 2-3 weeks with balanced or slightly higher phosphorus fertilizer; pinch back early growth to encourage branching; maintain consistent moisture
Flowering
6-8 weeks, extending through seasonAbundant trumpet-shaped flowers appear along stems; blooms occur in clusters; color is vivid and displays continuously
Continue regular fertilizing but reduce nitrogen to encourage more flowers; deadhead spent blooms to promote continued flowering; maintain consistent watering; humidity helps; provide full sun exposure
Sustained Bloom & Maintenance
Ongoing through fallPlant maintains dense flower production; vines continue to grow and fill trellis or support structure; foliage remains healthy
Fertilize every 2 weeks with blooming formula; continue deadheading; monitor for pests and mites; provide afternoon shade in extremely hot climates; reduce watering slightly in cooler months
Dormancy/Overwintering
3-4 monthsGrowth slows or stops; foliage may yellow or drop; plant enters rest period in cool climates
In frost-prone areas, bring container plants indoors or protect with frost cloth; reduce watering and fertilizing; prune back in spring; clean up fallen foliage; in zones 10-11, light pruning maintains shape
