I have a small backyard - around 100 square meters. I want to use a part of it to plant some fruit trees. What fruit trees should I pick in order to get the maximal amount of edible fruits per year?
The following information may be relevant: the garden is in a hilly region, about 800 meters above sea level. The temperatures in the winter (in celsius) are about 5-15, with about three extreme nights where the temperature at night is below 0. The temperatures in the summer are about 20-30. The humidity is about 70% and there is a fair amount of rain, but I am going to have a computerized watering system.
EDIT: here is a plan of the garden. The garden is green and the house is blue. The numbers are in centimeters. The black discs are sewer covers.
