Pummelo 'Nam Roi'
Known by many spellings (pomelo, pummelo), the Nam Roi is undeniably the most popular variety of citrus in Vietnam. Almost seedless, this enormous citrus offers similar qualities to a grapefruit, but with sweeter fruit. Easy to peel when ripe, and readily separating into segments for easy eating, the burst of juice is not only a treat for the taste buds, but is also packed full of both Vitamin A and Vitamin C.
Citrus grow best in open positions where they receive full sun, good drainage and shelter from strong winds. They prefer a frost free environment although will tolerate light frost once established. Citrus are well suited to pot culture and are no less productive when kept at 2m tall and 2m wide which also makes maintenance and care more manageable. Always use good quality potting mix in a pot. Citrus have a shallow fibrous root system and underplanting and cultivation below the tree should be avoided. Fertilise monthly with a complete, slow release, pelleted fertiliser all year round. Mulch to conserve moisture. Supplementary water is required during the warmer months. Prepare soil prior to planting by digging a hole twice as wide and deep as the root ball and enriching with compost and pelleted complete fertiliser. Apply seaweed solution after planting. Avoid planting into cold, wet soil.
