Are Kishu Mandarins always seedless or only seedless when grown in the absence of other citrus pollinators? I have a young tree that had fruit full of seeds the first two years. The taste is good and the fruit is smaller than other mandarins but I bought it because it was supposed to be seedless. The tree is still young but I didn't think that seed production varied with age. My honey tangerine and pixie tangerine seem to be better tasting and more productive. I also have two small gold nuggets, a small tango, and a large fremont so I won't be sad to see the Kishu go, I just read that so many people think it is the best Mandarin.
As possible pollinators besides the mandarins and tangerines, I have tahitian lime, meyer lemon, calamondin, fisher navel orange, cara cara orange, sweet lime, chandler pomelo, yuzu, and valencia orange.
Any comments would be appreciated.
