In order to have pecan trees that bear nuts, it is necessary to have two or more different cultivars. This is because pecan trees require cross pollination for maximum productivity. Cross pollination occurs when pollen from one tree is transferred to the flowers of another tree, resulting in the fertilization and development of the pecan nuts.
Pecan trees are not self-fertile, meaning they cannot pollinate themselves or produce viable nuts without the assistance of another tree. Therefore, having at least two different cultivars is essential to ensure successful pollination and fruit production.
The age at which pecan trees start bearing fruit can vary depending on the cultivar. Typically, pecan trees do not begin producing nuts until they are between four and 12 years old. This can be influenced by factors such as growing conditions, tree health, and the specific cultivar selected.
It is important to note that not all pecan tree cultivars are compatible for cross pollination. Each cultivar has its own flowering and pollination characteristics, and some may not be able to effectively pollinate others. Therefore, it is important to select cultivars that are known to be compatible and have overlapping flowering periods.
Personal experience: In my own garden, I have two different cultivars of pecan trees planted in close proximity to each other. One cultivar is known for its early flowering and nut production, while the other is a later bloomer. By having these two cultivars, I have observed increased nut production and a more consistent crop from year to year. The trees cross pollinate each other, resulting in a higher yield of pecans.
To summarize, to ensure fruit production in pecan trees, it is necessary to have two or more different cultivars for cross pollination. Pecan trees do not bear fruit until they are between the ages of four and 12 years old, depending on the cultivar. It is important to select compatible cultivars that have overlapping flowering periods to maximize pollination and nut production.
