It seems we are in an age of confusion when it comes to knowledge. There are different answers for most everything. A person can say that their fruit is better in part sun or shade and another will say that theirs is better in full sun. One person can say no and another say yes. I just say YMMV because that seems to be the truest statement.
‘Pear trees are well-suited for shaded gardens, with some varieties being more tolerant of lower light conditions. The European pear (Pyrus communis) can adapt to partial shade, particularly in regions with intense summer sun. Varieties such as ‘Bartlett,’ ‘Kieffer,’ and ‘Anjou’ are known for their ability to thrive in less sunny areas while still producing abundant and yummy fruit.’
Maybe a different thought process is not growing in the shade of other trees… but what about the most cloudy days?
Oregon, Washington, Michigan, New York have the most cloudy days… alot of fruit comes from those states.
My state for example-
6. West Virginia. The Allegheny Mountains that stretch along the border between West Virginia and Virginia are responsible for much of the overcast weather in this state. Because the Alleghenies trap moisture flowing into the state from the north and west, most of the state experiences only 60 to 65 clear days per year.
How will I grow an orchard with only 60 clear days per year?
Washington has the most cloudy days of any state other than Alaska and produces the most fruit i think.
