Shiranui Mandarin Citrus Tree
A Japanese hybrid between a Ponkan Tangerine and a Kiyomi Tangor, Shiranui Mandarin is one of the sweetest, if not the sweetest fresh eating citrus varieties available. Fruits are large and have a bump on top of the fruit near the stem that resembles the topknot hairstyle of Japanese sumo wrestlers, which is where it gets its trademark name you might have seen in the grocery stores but that we’re not allowed to use. It’s easy to see why this has become one of the top selling citrus anywhere it is grown.
Latin Name: Citrus hybrid
Site and Soil: Shiranui Mandarin likes 1/2 day to full sun and well drained soil. If growing it in a pot, in the winter place your plant in a well-lit room. Potting soil should be coarse, acidic, and well-drained.
Rootstock Description: Flying Dragon is a hardy and very dwarfing rootstock for Citrus that induces very early flowering and fruit production. Trees grown on Flying Dragon will rarely exceed 5 ft. in height and will often produce fruit the year they are planted.
Pollination Requirements: Self-fertile. You can help it set fruit by taking a small brush and moving pollen from flower to flower.
Hardiness: Hardy to at least 25F but any frost below 32 degrees will ruin the fruit.
Bearing Age: 1-2 years after planting
Size at Maturity: 4-8 ft.
Bloom Time: Spring
Ripening Time: Meiwa Kumquat ripens in late fall to winter.

Pests & Diseases: While outside, Citrus plants will likely not be bothered by insect pests. Be on the lookout for slugs. Indoors, Citrus can have mites, scales and/or aphids. Watch carefully for any problems and treat with an insecticidal soap or wash them off. We have not seen any disease problems on our Citrus plants.
