|Two days later, and all four mandarins have now fallen on their own accord. The one that, from the outside, looked the best, was already soft and mushy, so I hoiked it. This was the next to fall. The skin did not look "picture perfect", but there were no seeds, and plenty of juice. However, it lacked in flavour. Let me check Daley's cultivation notes.|
Dwarf Mandarin - Okitsu Wase (Satsuma)
Seedless, good flavour, low acid and high TSS. Satsumas are cold hardy and form a compact growing tree. They are the earliest mandarins in the marketplace.
So ... I went looking in some Californian forums for hobby citrus growers. Sataumas are ready BEFORE the skin is fully orange, so pick early. They mature well on the shelf. If you wait until the skin is ripe on the tree, the fruit inside will have spoiled. Bingo!
