Pomeroy is a dwarfing disease-resistant diploid citrus rootstock, compatible with most citrus species, but particularly suitable for sweet orange cultivars.
Pomeroy is a "large-flowered" form of Citrus trifoliata and citrus trees grafted on Pomeroy rootstock typically reach about 3m - 3.5m mature height.
Fruit size is generally improved over the more dwarfing Flying Dragon rootstock.
Pomeroy rootstock is very cold-hardy, down to -20C, and also imparts some additional cold-hardiness to the scion variety.
It is tolerant of damp soils over winter.
These rootstocks are bio-certified, and raised from seed. The rootstocks are naturally thorny, but this does not affect the scion variety.
