Growth Stages

1

Seed germination

7-14 days

Seeds 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.

2

Seedling & establishment

2-3 weeks

Vines 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.

3

Vegetative growth

3-4 weeks

Vigorous 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.

4

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.

5

Seed production & decline

Until frost

Flowers 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.
