Harvesting: 'Long Purple' should be harvested when the fruit is 8"–10" long and the skin is still shiny. If you are in doubt about maturity level, note that it's better to harvest eggplants a little young rather than wait until they are overly mature with dull skin, eventually possibly turning a golden color, with plentiful seeds, and bitter taste. To harvest, cut the stem with pruners. Plants will produce four or more fruits. Continual harvest will encourage more production.
