How cold hardy are pecan trees?

As a general rule, pecan trees can grow in hardiness zones 7-9, with some varieties being able to stretch outside of this. Pecan trees don’t like to get too cold. An average of 45 to 55 degrees in the winter is ideal, but they can withstand temperatures down to 20 degrees below zero.

Many pecan tree cultivars are alternate bearing, which means that they produce heavy and light crops during alternate years or heavier crops once every two to three years.

Can a single pecan tree produce nuts?

Oftentimes, a single tree won’t produce very many nuts, since the female and male flowers don’t bloom at the same time. Pecans that shed pollen (from the male catkin) before the female flower is mature are ‘Type I’ pollinators.

Why did my pecan tree not produce this year?

Alternate pecan production (on and off years) is mainly the result of inadequate fertilization. When trees set a large nut crop, there are not enough nutrients for both that year’s nuts to mature and for the tree to store enough plant food for adequate production in the following year.
