Zone 6 Nut Trees – Best Nut Trees For Zone 6 Climates
Hazelnuts are one of the most popular nuts in America. They have been grown for centuries and they continue to thrive here today. Hazelnuts are very high in protein and low in fat, making them excellent sources of energy.
Hazelnuts are rich in vitamins A, C, E and K, iron and manganese, calcium, phosphorus and potassium. They are also good sources of fiber, folate, thiamin and niacin.
The hazelnut tree grows from Mexico to Canada and southward into South America. It is native to North Africa, Spain and Portugal. There are two species of hazelnuts: the European hazelnut (Juglans regia) which grows naturally throughout Europe; and the Mexican hazelnut (Carya ovata).
Both varieties grow well in temperate climates.
Both types of hazelnuts are edible, but the Mexican variety is preferred because it contains higher levels of vitamin E than other varieties. The hazelnut tree is not invasive like many other trees. It prefers full sun and fertile soil with a pH level between 5.5 and 6.0.
It is a very hardy tree and can survive in most climates.
Hazelnut trees thrive in zones 4 through 8. If you are not sure what zone you live in, please see this map.
Hazelnuts typically grow to between 8 and 20 feet tall, but they can grow taller. These plants can be either monoecious or dioecious, which means that individual plants produce only male or female flowers. The male trees do not produce fruit, but female trees must be grown for cross-pollination.
It takes about three or four years for the plant to begin bearing fruit, and the tree will keep producing as long as it lives.
Hazelnuts can be eaten fresh off the tree in their shell, or they can be shelled and eaten raw, roasted or turned into paste. You can also use them to flavor baked goods, candy and ice cream. They are a common ingredient in gourmet coffee.
Hazelnuts can also be ground into a paste and used as a butter substitute in baking or cooking. Hazelnut oil is also used as a salad oil or as a condiment.
Hazelnut is not only delicious; it’s good for you too! In addition to being high in vitamins and minerals, hazelnuts also contain a lot of fiber and protein.
