Care Guide
Watering
Water when topsoil is fully dry; reduce frequency during prolonged heatwaves to avoid stress
Fertilization
Apply diluted low-nitrogen liquid feed once every 4 weeks. Over-fertilization can reduce fruit production and increase foliage growth
Eggshell powder topdressing：Crush dried eggshells into fine powder; lightly mix into top 2 cm of soil at planting time to provide slow-release calciumPruning
- Trim overgrown trailing vines to maintain garden space and improve air circulation
- Remove yellowing leaves and spent flowers to reduce pest and disease pressure
