Citrus plant (Kumquat) (Bowerham LA1)

A mature plant in a 40cm pot. Kumquats are small edible citrus fruits 1-2cm. Citrus is best in good compost (John Innes no3 with added drainage and possibly a bit of lime to get pH 6.5). Best in a green house or conservatory as can't really cope with sustained hard frost. I have demolished my greenhouse so seeking a good home for the plant.
