Establishment
3-6 monthsYoung vine with minimal growth; small leaves and delicate stems emerging from soil
Water consistently, provide sturdy support structure, protect from harsh winds, apply mulch around base, do not fertilize aggressively
Vegetative Growth
6-12 monthsVigorous vine development with increasingly larger leaves, tendril formation, and climb along support structure
Guide vines along trellis, maintain consistent watering, begin light feeding in spring with balanced fertilizer, remove any dead wood
Budding & Flowering
4-12 weeks depending on variety and climateFlower buds form at leaf nodes; flowers open in succession, displaying full range of color and petal patterns
Ensure consistent water supply during flowering, deadhead spent blooms to encourage more flowers, provide light support as vine becomes heavy with blooms
Seed Development
4-8 weeksAfter flowering, seed heads form with distinctive feathery, silver-gray plumes
Can deadhead seed heads to promote reflowering on some varieties, or leave for ornamental winter interest and self-seeding
Dormancy
3-4 monthsLeaves drop (deciduous varieties) or remain sparse (evergreen varieties); vine goes dormant in winter
Perform dormant season pruning according to variety type (see pruning groups), remove diseased or damaged wood, mulch around base for frost protection in cold zones
