Well as they say, an Apple a day keeps the doctor away and it should definitely be applied to most of the hardy citrus trees. I sometimes wonder as I walk around my California neighborhood as to why we still even buy limes, lemons and other citrus fruits in the stores because they can be found all over as they light up every other space among the landscaped and overflowing wild gardens in town.
We only have a potted Calamansi citrus tree in our yard. The most popular, traditional seasoning and drinking citrus amongst Filipinos. We normally get abundant fruits (20-30) every harvest, but this last round it set only about 10 fruits so they grew a lot bigger than normal.
