Plant Needs

☀️
Sunlight Requires 6–8 hours of full direct sunlight daily for optimal fruit production; tolerate partial shade in extremely hot climates to prevent fruit sunscald
💧
Watering Keep soil consistently moist but not waterlogged; water deeply at the base of the plant to avoid wetting foliage, which can trigger fungal diseases
🌡️
Temperature Thrives in 18–27°C; frost-sensitive, so avoid exposing to temperatures below 10°C or above 32°C, which can halt fruit set
🔍

Characteristics

  • Leaf: Compound pinnate leaves with fuzzy, aromatic, slightly sticky foliage
  • Flower: Small, star-shaped yellow blooms in loose clusters of 5–10 flowers
  • Fruit: Green unripe berries that ripen to red, orange, or yellow fleshy edible fruit
  • Stem: Hairy, branching stems; indeterminate varieties produce tendrils for climbing

Care Guide

Watering

Keep soil evenly moist, watering deeply 2–3 times per week during hot, dry periods

Fertilization

Apply balanced, slow-release fertilizer at planting; supplement with phosphorus-rich fertilizer when flowers appear. Avoid over-fertilizing with nitrogen, which can promote excessive foliage growth at the expense of fruit production

Composted banana peel tea:Compost banana peels for 2–3 weeks, steep in water for 3 days, dilute 1:20 with water, and apply as a root drench to avoid foliage contact
Pruning
  • Remove suckers (small side shoots) from determinate varieties to channel energy into fruit production
  • Trim lower yellowing leaves to improve airflow and reduce the risk of soil-borne fungal diseases
  • Support indeterminate vines with stakes or cages to prevent stem breakage under the weight of ripening fruit
  • Harvest ripe fruit regularly to encourage continued blooming and fruit set throughout the growing season
⚠️
