Growth Stages

1

Seedling

4-6 weeks

Tender young plants with 2-4 leaves, pale green coloring, developing root system

Keep soil warm (70-75°F) and consistently moist. Provide bright indirect light. Protect from cold temperatures and strong winds.

2

Vegetative Growth

3-6 months

Rapid vine extension with alternating leaves, tendrils forming along stems, establishing climbing structure

Provide sturdy support structure or trellis. Regular feeding with balanced fertilizer every 3-4 weeks. Prune to direct growth and encourage branching.

3

Flowering

2-4 months, intermittent flowering

Production of stunning flowers with white sepals, purple-banded petals, and elaborate corona filaments with purple and white bands

Maintain consistent moisture and temperature. Apply phosphorus-rich fertilizer to encourage blooms. Ensure adequate pollinator access.

4

Fruit Development

90-120 days

Small green fruits forming where flowers bloomed, gradually enlarging and transitioning to yellow-green color

Thin fruits if overcrowded (spacing 6-8 inches apart on vine). Maintain steady moisture. Apply potassium-rich fertilizer. Protect from excessive heat.

5

Maturity & Harvest

At harvest readiness

Fruits reach full yellow color (some show red blush), become slightly soft when squeezed, emit strong fragrant aroma

Allow fruits to fully ripen on vine for best flavor. Harvest when fully colored and slightly yielding to pressure. Can be harvested and ripened off vine if needed.

Common Pests

  • Hand-pick larvae or accept some leaf damage as part of butterfly lifecycle. Use fine netting if necessary. Encourage natural predators.

  • Spray with water to dislodge. Apply neem oil or insecticidal soap. Increase humidity to discourage infestation.

  • Remove with soft brush or cloth. Apply horticultural oil in dormant season. Introduce natural predators like ladybugs.

  • Use yellow sticky traps. Spray neem oil or insecticidal soap. Maintain good air circulation.

  • No chemical cure; use resistant rootstocks if available. Ensure excellent drainage. Remove infected plants to prevent spread.

Harvest Tips

Fruits are ready to harvest when fully yellow (40-60 days after flowering) and slightly soft to touch. They should release a sweet, aromatic fragrance. Granadillas can be hand-picked by gently twisting or cut with pruners. Fruits continue to ripen slightly after harvest but taste best when vine-ripened. Store at room temperature for a few days or refrigerate for up to 3 weeks.

Fun Facts
