Okitsu Wase Mandarin Citrus Tree
There aren’t many citrus that we could eat more of than the Okitsu Wase Mandarins. Their snackable size, delicious sweetness with balanced acidity and easy peeling make this a very popular variety and the most widely planted citrus in Japan where it originated. Incredibly early ripening, (Wase means early in Japanese, so anytime you see that you can be sure it’s a good fit for short growing seasons.) Okitsu Wase is one of the easiest to grow fresh eating citrus for northern growers.
Latin Name: Citrus unshiu
Site and Soil: Okitsu Wase Mandarin can be grown outdoors in regions with mild winters. It 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: Meiwa Kumquat is self-fertile. You can help it set fruit by taking a small brush and moving pollen from flower to flower.
Hardiness: Meiwa is hardy to at least 20F and has reportedly survived temperatures even lower than that. Definitely worth trying in Zone 8!
Bearing Age: 1-2 years after planting
Size at Maturity: 4-6 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.
