Seed germination
7-14 daysSeeds sprout and first true leaves emerge; plant remains low and compact near soil level.
Soak seeds overnight or scarify with sandpaper before planting to improve germination. Keep soil warm (70-80°F). Provide indirect light initially.
Seedling & establishment
2-3 weeksVines begin rapid growth; heart-shaped leaves expand and stems elongate; plant reaches 4-6 inches tall.
Provide sturdy support (trellis, stakes, or string). Water consistently. Begin fertilizing weekly with balanced fertilizer once true leaves appear.
Vegetative growth
3-4 weeksVigorous vine development with dense foliage coverage; stems climb and spread across support structures.
Guide vines along support structure. Pinch back excessive growth to promote bushiness. Maintain consistent moisture and weekly fertilizing.
Flowering
6-12 weeks (until frost)Abundant trumpet-shaped flowers bloom along the vine; flowers open in early morning and close by early afternoon.
Reduce nitrogen fertilizer to encourage more blooms over foliage. Continue watering and deadhead spent flowers to promote continuous blooming.
Seed production & decline
Until frostFlowers fade; seed pods develop; vines slow growth as temperatures cool; plant dies back at first frost.
Allow some flowers to go to seed if you want self-sown plants next year. Cut back dead growth after frost. In mild zones, perennial varieties may regrow.
