- Light
- Full sun to partial shade, ideally receiving at least six hours of direct sunlight daily for optimal fruit coloration.
- Water
- Requires regular watering during the first growing season to establish a deep root system. Once established, it is moderately drought-tolerant but performs best with consistent moisture.
- Growth
- A vigorous perennial deciduous climbing vine that uses tendrils to scale supports. Can reach lengths of 15 to 20 feet or more with a rapid growth rate.
Care instructions
