Do you need 2 hazelnut trees to get nuts?

Although hazelnuts are monoecious (they have male and female flowers on the same tree), they are self-incompatible, meaning a tree cannot produce nuts with its own pollen. So the answer is yes, they have to cross-pollinate. If a hazel tree is more than five years old and has not yet produced nuts, the tree is likely to lose its mate. Hazelnuts require cross-pollination of a different hazelnut cultivar to produce a nut crop.

You must grow two hazel trees with strong genetic differences, one as a pollinator and one as a producer to get a nut crop. These trees must be about 65 feet apart from each other for cross-pollination to occur. Some things go really well together, like pancakes and maple syrup. But there are other winning combinations that few people know.

One of them is the cultivation of hazelnuts (Corylus) together with truffles. Truffles are a sought-after edible mushroom. They're hard to find, they don't stay fresh for long, and they're incredibly expensive to buy. They grow underground and attach to the roots of certain types of trees, such as hazel, oak and beech.

Teamwork benefits both truffles and trees. Truffles help tree roots access soil water and nutrients. In return, fungi absorb sugary juices exuded from tree roots. Scientists continue to study the most effective ways to inoculate hazelnuts with truffle spores, but in the meantime, growers who have invested in Earthgen truffle inoculated hazelnuts will have to wait and see.

It can take 6 to 10 years until both crops are mature enough to harvest. For layered propagation, a branch is taken, and for the simplest type of layers, it can be placed in the ground. And then it produces new roots where the soil is. And then you cut it from the original plant.

Basically, you're bending the branch, they bury it, and then a whole new plant will grow. And it will take about two years to get it uprooted. This is an inexpensive way to propagate a plant, but it is difficult for mass production. On August 21, Adam Koziol of EarthGen International Ltd was weeding his potted hazel trees and found his first truffles in one of the pots.

Native hybrid hazelnuts provide a crop that is constantly in short supply, is well known to consumers, and is almost self-grown. Once the bush is in the ground, you just have to wait a few seasons until you can start filling your home with the buttery scent of fresh roasted hazelnuts. The potential loss of these “developmental dropouts” amounts to 75— 85% of the total individual flowers produced by the tree. Some of the flowers in clusters that do not fall from the tree (because at least one nut has developed normally) are also subject to stopped growth.

Hermes, the messenger of the Greek gods, was said to carry a cane made of the wood of a hazel tree to provide him with wisdom and guide him on his travels. Hazel trees are wind pollinated and there must be a compatible pollinator variety for effective pollination. While most trees bloom and pollinate during spring, hazel is unusual, as it blooms and pollination occurs during the winter. And by the fourth year, you know you're getting quite a few catkins and you can harvest some hazelnuts.

Once a tree is established, in its second to fifth year, you will begin to notice hazelnut formation during the month of May. I'm just trying to establish if there is really NO competition for this market in my area, where hazelnuts seem to grow very well everywhere, even partly with shade and clay soil. .
