Described are compositions and methods to mitigate alternate bearing of perennial crops by use of a natural metabolite. In particular, the present disclosure provides a natural metabolite in the presence or absence of an auxin transport inhibitor to increase floral intensity (flower number) of the return bloom in the spring following the setting of a heavy on-crop to increase the yield of the putative off-crop year and, thus, increase cumulative crop yield. Additionally the present disclosure provides a natural metabolite in combination with one or both of a growth promoting type of plant growth regulator, and a hormone biosynthesis, transport or function inhibiting type of plant growth regulator.
