Citrumelo 4475 is a tetraploid cold-hardy dwarfing citrus rootstock, mainly used for sweet oranges and grapefruit. It produces a grafted tree with a mature height of around 4m – 5m. It is cold-hardy to around -12C.
Tetraploid citrus rootstocks are thought to be more tolerant of water stress and nutrient deficiencies than diploid citrus rootstocks.
These rootstocks are bio-certified, and raised from seed. The rootstocks are naturally thorny, but this does not affect the scion variety.
Prices are per rootstock, contact us for a discount for larger quantities. The 1-year plants are about 35cm.
