In order to get nuts from hazelnut trees, it is generally recommended to have at least two trees for cross-pollination. This is because hazelnuts are self-incompatible, meaning that a single tree cannot set nuts with its own pollen.
Cross-pollination is the transfer of pollen from the male flowers of one tree to the female flowers of another tree. In the case of hazelnuts, the male flowers produce pollen and the female flowers contain the ovules, which when fertilized by pollen, develop into nuts.
Having two or more hazelnut trees of different varieties ensures that there is a sufficient exchange of pollen between the trees. This increases the chances of successful pollination and nut production. It is important to note that hazelnut trees need to be of compatible varieties to cross-pollinate effectively.
When selecting hazelnut varieties for cross-pollination, it is advisable to choose varieties that have overlapping flowering times. This helps to ensure that the male flowers of one tree are receptive when the female flowers of another tree are ready for pollination.
It is also beneficial to consider the compatibility of the varieties in terms of their flowering times and genetic compatibility. Some hazelnut varieties are known to be more effective in cross-pollination than others. Consulting with local nurseries or agricultural extension services can provide valuable information about suitable hazelnut varieties for specific regions.
In my personal experience, I have observed the benefits of cross-pollination in hazelnut trees. A few years ago, I planted two hazelnut trees of different varieties in my backyard. Initially, both trees produced flowers, but there were no nuts. After some research, I discovered the importance of cross-pollination in hazelnuts.
The following year, when both trees were in bloom, I noticed an increase in bee activity around the trees. This was a good sign, as bees are important pollinators for hazelnuts. As the season progressed, I observed the formation of small green nuts on both trees. Eventually, these nuts matured and I was able to harvest a decent crop of hazelnuts.
This experience reinforced the importance of having multiple hazelnut trees for cross-pollination. Without the presence of another compatible hazelnut tree, the flowers on my first tree would not have been pollinated and no nuts would have been produced.
If you want to get nuts from hazelnut trees, it is advisable to have at least two trees for cross-pollination. Hazelnuts are self-incompatible, meaning they need pollen from another compatible tree to set nuts. By planting multiple hazelnut varieties with overlapping flowering times, you increase the chances of successful pollination and nut production.
