BMc what are they grafted on in Australia, do you know?

Although no formal rootstock trials have been undertaken for finger limes they are most commonly budded onto Citrus trifoliata or Troyer citrange rootstocks. To date no obvious incompatibility on these rootstocks has been reported. C. trifoliata is the preferred rootstock for heavy clay-loam soils or in areas with high or frequent rainfall. Most finger limes grown in coastal areas are budded onto C. trifoliata for protection against Phytophthora root rot. Rootstock choice should always match soil and climatic conditions.
