In spite of the fog and cold summers in the Bay Area you can still quite successfully grow citrus fruits. Since we have a smaller patio we went with a dwarf meyer lemon tree. Although the exposure is to the Northeast, the fact it is nearly rooftop will allow for 8+ hours of sun every day. The only concern will be too much wind and we are prepared to deal with that if the need arises. This tree is straight, about 4 feet tall, and is blossoming already. In fact, I am hoping that by the end of the summer there will be some fruit to harvest! Last but not least, we named this plant Oscar. As in Oscar Mayer. Mayer = Meyer! BOOM! My cleverness knows no bounds!
