Plant Needs

☀️
Sunlight Requires 6–8 hours of direct sunlight daily for optimal blooming; tolerates partial shade in extremely hot climates to prevent leaf scorch.
💧
Watering Water deeply when the top 2 cm of soil feels dry; avoid overwatering to prevent root rot, as the vine is moderately drought-tolerant once established.
🌡️
Temperature Thrives in warm temperatures between 18–30°C; protect from frost below 10°C, as cold temperatures will kill the vine in non-hardy regions.

Care Guide

Watering

Keep soil consistently moist during active growth to support vine expansion and blooming

Fertilization

Apply diluted balanced liquid fertilizer every 2 weeks to support new growth. Avoid over-fertilizing, as excessive nitrogen can reduce flower production and promote foliage growth over blooms.

Banana peel tea:Chop 2–3 banana peels and soak in 1 gallon of water for 3 days; strain out solids and dilute the tea 1:1 with water before applying to the soil around the base of the vine.
Pruning
  • Trim overgrown or tangled stems in early spring to encourage bushier, more compact growth.
  • Deadhead spent blooms regularly to redirect energy toward producing new flowers.
  • Remove damaged, yellowing, or diseased foliage to improve airflow and reduce pest risk.
  • Cut back the vine to 30–60 cm in late autumn in non-hardy regions before frost hits.
