Natural crop load regulation during bloom
The reproductive energy needed to create female flowers each spring is determined by the previous season's nut set and the tree's overall vigor. An excessive crop load one year is often followed by a year of weak pistillate flower formation (hence pecan's tendency towards alternate bearing). Drought, excessive flooding, lack of soil nutrients, insects and diseases can all put stress on a tree and reduce the strength of flower formation the following spring.
So next time you start blaming poor pollination weather on your lack of pecan crop, think back to what happened last year. Did you do everything possible to ensure healthy tree growth?
