Propagated by seed or budding. Seed should be harvested from ripe fruit, washed thoroughly, and sown in containers immediately. Sow stored seeds in containers as soon as possible. Germination usually occurs within 2-3 weeks. Seedlings must be watered and kept well ventilated. Spacing 5 m x 6 m (333 trees/ha). 'Indian River',' Bessie' and 'Madam Vinous' rootstocks are resistant to foot rot. Irrigation required during dry periods following planting (10 L water per week). Put 1 kg rock phosphate in the bottom of the hole at planting. After returning and settling top soil the plant should be above field level to reduce the risk of foot rot. In wet areas a cover crop is necessary to prevent erosion (Pueraria phaseoloides is one recommendation).Regularly attacked by Citrus Greening Citrus Vascular Phloem Disease (CPVD), especially at lower altitudes (<1000 masl) but less affected by CVPD at higher altitudes (>1000 masl). Able to withstand dry periods and poor soil but it prefers a deep, well-drained yet moisture retaining loamy soil and full sun. Trees are hermaphroditic and insect pollinated.
