Latin Name: Poncirus trifoliata x Citrus paradisi
Site and Soil: In spring, summer and fall, keep your potted Citrus in a location with 1/2 day to full sun. In the winter, place your plant in a well-lit room if you live in USDA Zone 7 or below. Potting soil should be coarse, acidic, and well-drained.
Rootstock Description: Flying Dragon is a hardy and very dwarfing rootstock for Citrus that induces very early flowering and fruit production. Trees grown on Flying Dragon will rarely exceed 5 ft. in height and will often produce fruit the year they are planted.
Pollination Requirements: Citrumelo Hardy Grapefruit is self-fertile. You can help it set fruit by taking a small brush and moving pollen from flower to flower.
Hardiness: Citrumelo Hardy Grapefruit should be hardy to at least 20 degrees F. We recommend moving it to a well-lit and protected location in the fall before hard frosts occur if you live in cold climates.
