cooked Posted December 6, 2018 Share Posted December 6, 2018 Like many other fruit trees, a good fruit bearing year may be followed by a bad (or two). In addition, although they don't need frost, they need low winter temperatures in order to flower. Some apple trees tend to bear fruit irregularly also and I seem to remember that there was some kind of spray proposed. (Gibberelin?) I think insects can be ruled out.
