Start with a grafted sapling for the best chance of success.
A healthy, grafted carambola sapling and well-draining soil.
Plant in spring or early summer when temperatures are warm.
Use a light, sandy loam soil with good drainage. Ensure containers have adequate holes for water to escape.
Transplant the sapling into its permanent spot, ensuring it is at the same depth as in the nursery pot.
Water regularly to keep soil moist but not soggy. Avoid direct sunlight for a few days after planting.
Provide full sun and regular watering, especially during dry spells. Fertilize with a balanced fertilizer in spring and summer.
