Growth Stages

1

Seedling

4-8 weeks

Young vine with tender leaves and developing root system; height 3-6 inches

Keep soil consistently moist; provide gentle support or stake; protect from strong wind; maintain warm temperatures (70-85°F)

2

Vegetative Growth

3-6 months

Vine rapidly extends with increasing foliage; deep green compound leaves; height 1-3 feet

Install sturdy trellis or support structure; prune to encourage branching; fertilize every 2-3 weeks with balanced fertilizer; maintain consistent moisture

3

Flowering

6-8 weeks, with flowers appearing throughout warm season

Distinctive white and purple corona-like flowers appear; flowers 2-3 inches wide; vine 4-8 feet tall

Ensure adequate pollinator access; reduce nitrogen fertilizer to encourage flowering; maintain consistent watering; hand-pollinate if pollinators are scarce

4

Fruiting

2-3 months from flowering to maturity

Small green fruits develop behind flowers; gradually enlarge and turn purple; fruits 1.5-3 inches diameter

Thin excessive fruits to 6-8 inches apart for larger fruit; maintain consistent moisture and fertilizer; support heavy fruit with netting if needed

5

Harvest

Continuous harvesting from 1-2 years after planting through growing season

Fully ripe fruits are wrinkled and deep purple; pulp inside is aromatic and sweet-tart

Harvest when fruits fall naturally or are easily removed; store at room temperature or refrigerate; prune lightly after harvest to maintain shape

Harvest Tips

Harvest fruits when fully ripe and deep purple, typically 2-3 months after flowering. Ripe fruits will fall naturally from the vine or can be gently twisted and pulled. The fruit is ready to eat when the skin is wrinkled. Cut the fruit open and scoop out the juicy pulp with a spoon. Store at room temperature for a few days or refrigerate for up to 2 weeks.
