Farming method
Sow indoors 6 to 8 weeks before the last frost. Sow seeds 3–6 mm (1/8–1/4") deep in a light potting mix. Maintain a temperature of 23–29°C for rapid germination in 5 to 10 days . Reduce watering and nitrogen during hardening off to strengthen seedlings before transplanting.
Transplant when the risk of frost has passed. Space plants 60 to 90 cm (24 to 36 inches) apart, with 120 to 180 cm (4 to 6 feet) between rows. Provide full sun (level 3) and regular watering (watering level 3) . Due to the significant weight of the fruit, install sturdy supports .
Harvesting and preservation
Harvest when the red or white fruits have fully developed their color. To bring forward the harvest, pick those that have shown their first signs of color , then let them ripen off the vine at 22°C or higher . Store them between 12 and 21°C with 95% relative humidity to preserve their melting texture.
