Citrus maxima (Pummelo)

Pomelo, Pummelo, Shaddock, Pompelmous, Pamplemousse, Citrus decumana, Citrus grandis


Citrus maxima (Pummelo) is a large evergreen shrub or small tree, prized for its huge, round to pear-shaped fruits that resemble grapefruits. The shrub or tree has somewhat a weeping habit with the heavy fruits hanging from the bottom of the tree. A mature Pummelo tree can reach 50 ft. in height (15 m) and have a trunk up to 12 in. thick (30 cm). The oval leaves are very large, 8 in. long (20 cm), glossy above, dull and minutely hairy beneath. Fragrant flowers appear throughout the year. Green to pale yellow, the fruits are the largest of all citrus and may weigh as much as 5 pounds (2kg). There are even some records of fruits weighing up to 20 pounds (10kg) ! The rind is very thick and the flesh is sweeter and less bitter than the flesh of grapefruits. Generally, they contain only a few seeds. However, a pummelo cross-pollinated by another pummelo is apt to have many seeds. Pummelo fruits can be stored for 2-3 months without suffering from deterioration. Some of the more common varieties of pummelo include: Chandler, Ichang, Red Shaddock, Reinking, and Webber.

  • Grows up to 15-50 ft. tall (4.5-15 m).
  • A full sun lover, this plant is easily grown in loamy, moist but well-drained soils. Needs water regularly but cannot stand flooding or saturated soils. Apply a balanced liquid every 2-3 weeks during the growing season. Water sparingly in winter.
  • No routine pruning necessary. Remove diseased, damaged, congested or crossing shoots.
  • Generally disease free. Keep an eye out for scale insects, mealybugs and glasshouse red spider mite.
  • Propagate by semi-ripe cuttings in summer, or layer in early spring. Sow seed at 61°F (16°C) in spring.
