The seed is best sown in a greenhouse as soon as it ripe after thoroughly rinsing it. Sow stored seed in March in a greenhouse. Germination usually takes place within 2 - 3 weeks at 13°c. Seedlings are liable to damp off so they must be watered with care and kept well ventilated. The seed is usually polyembrionic, two or more seedlings arise from each seed and they are genetically identical to the parent but they do not usually carry any virus that might be present in the parent plant. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least three growing seasons before trying them outdoors. Plant them out in the summer and give them some protection from the cold for their first few winters outdoors. Cuttings of half-ripe wood, July/August in a frame.Layering in October.

Reasonably cold resistant, dormant plants can tolerate temperatures down to about -10°c, especially if they are grafted onto a Poncirus trifoliata rootstock. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[K].A group of hybrids of garden origin, Poncirus trifoliata x Citrus paradisi. Generally, these hybrids combine the qualities of cold hardiness and bitterness from Poncirus trifoliata with the larger fruits of the grapefruit, Citrus paradisi. They are occasionally cultivated for their edible fruit, but more usually for their use as a rootstock, there are some named varieties.
