Flying Dragon Rootstock: Dwarf Citrus Trees in NZ

Flying Dragon is a dwarfing citrus rootstock that keeps a citrus tree to about 1.5โ€“2 metres tall while it still carries full-sized fruit. Flying Dragon Nursery in Kerikeri introduced this rootstock to New Zealand in the 1980s, and it is where our name comes from. Most of our citrus varieties are available on a choice of two rootstocks: Flying Dragon (dwarf) and Rubidoux Trifoliata (semi-dwarf).

What is Flying Dragon rootstock?

Flying Dragon is a naturally dwarfing form of trifoliate orange (Poncirus trifoliata 'Flying Dragon') with twisted stems and curved thorns. It has been treasured in Japan for centuries. When a citrus variety is grafted onto it, the rootstock restricts the size of the tree without reducing the size of the fruit. A citrus tree that would normally reach 3โ€“5 metres tall and 3โ€“4 metres wide becomes a compact tree of around 1.5โ€“2 metres.

Why choose a dwarf citrus tree?

  • It fits in a large pot, on a balcony or in a small courtyard.
  • Fruit is easy to reach, and the tree is easy to net, prune and protect from frost.
  • You can grow several varieties in the space of one full-sized tree.

When is Trifoliata the better choice?

Rubidoux Trifoliata is a more vigorous rootstock that gives a strong, healthy root system and a bigger tree. Choose it if you have room and want larger crops. The final height depends on the variety grafted onto it, your growing conditions and how you prune.
