Do Walnut Trees Need Another Tree for Pollination or Can I Get Nuts from Just a Single Tree?
Walnut trees, like many other fruit and nut trees, require cross-pollination to produce nuts. This means that you will need to plant at least two walnut trees of different cultivars within close proximity to each other to ensure successful pollination and nut production.
The male and female reproductive organs of walnut trees are located on different flowers. Male flowers produce pollen, which is carried by the wind or insects to female flowers. The female flowers then produce nuts. If there is only one walnut tree, the pollen from its male flowers will not be able to reach the female flowers, and there will be no nut production.
The distance between the two trees can vary depending on the cultivar of walnut tree. However, it is generally recommended to plant the trees no more than 100 feet apart. This will ensure that there is sufficient pollen transfer between the trees.
Walnut trees can live for up to 100 years. However, they will not begin producing nuts until they are 5-7 years old. Once they start producing nuts, they will continue to do so for many years.
