Transplant when all 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) , regular watering (watering level 3) , and install sturdy staking , essential for supporting indeterminate growth and abundant fruit.
