Introduced to NZ by Flying Dragon Nursery — our signature rootstock for anyone wanting a beautiful, productive citrus tree without needing a big garden.

• Far superior to other Trifoliatas on the NZ market — better vigour, better results
• Outstanding cold hardiness — in freeze trials Rubidoux showed zero bark splits while other rootstocks suffered significant damage
• Higher sugar content — produces sweet, high quality fruit across all citrus varieties
• High yielding — produces abundant fruit at maturity
• Grows 2.5–3.5m — ideal for open gardens and orchards
• Disease resistant and proven across all NZ growing conditions

Rubidoux Trifoliata is the rootstock we trust above all others for open gardens — stronger trees, bigger harvests, and built to last in the NZ climate.

A rootstock is the root system your citrus tree is grafted onto. It controls how big your tree grows, how cold-hardy it is, and how quickly it fruits. The variety you’re buying stays exactly the same — only the tree size and vigour changes.

Yes — choose Flying Dragon (Dwarf). Use a pot at least 50cm wide with good quality citrus mix and feed regularly through spring and summer.

Our trees are around 2.5 years old and most are already at fruiting stage. We remove flowers and fruit before shipping so your tree puts all its energy into establishing roots first. We recommend removing flowers and fruit in the first season after planting — a little patience means a much bigger harvest from year two onwards.
