I have a well established avocado tree of probably 30-40 years in San Jose, CA 95112. It is about 25 feet tall. I believe this is a Bacon or a Zutano variety (elongated pear shape with green thin skin).
This years crop looks exactly like previous years, however there are beige lumps (about the size of an apple seed) in the avocado meat that are kind of papery. This is similar to the strings that you sometimes get especially in very ripe avocados, but they are not attached to anything. This makes them quite unpleasant to eat.
Any idea what this might be?
Last year I fertilized the plant with citrus/avocado fertilizer like I have done before. Also I didn't water as much as I have in previous years.
