When To Pick Hazelnuts: A Definitive Guide to the Perfect Harvest
The ideal time to pick hazelnuts is when they are fully mature, indicated by a color change from green to light brown and when they begin to fall naturally from the tree in late summer to early fall. This ensures optimal flavor and storage potential.
A Historical Overview of Hazelnut Cultivation
Hazelnuts, also known as filberts, boast a rich history dating back thousands of years. Archaeological evidence suggests that they were a staple food source for prehistoric humans in Europe and Asia. These nutrient-dense nuts were not only consumed directly but also incorporated into various culinary traditions. The cultivation of hazelnuts intensified with the rise of agriculture, and today, they are grown commercially in many regions worldwide, prized for their distinctive flavor and nutritional value. Major producing countries include Turkey, Italy, and the United States (specifically Oregon).
The Nutritional Powerhouse: Health Benefits of Hazelnuts
Hazelnuts are more than just a delicious snack; they are a nutritional powerhouse packed with essential vitamins, minerals, and antioxidants. Regularly incorporating hazelnuts into your diet can contribute to several health benefits. Some key advantages include:
- Heart Health: Hazelnuts are rich in monounsaturated fats, which can help lower bad cholesterol levels and reduce the risk of heart disease.
- Brain Function: The high vitamin E content in hazelnuts protects brain cells from damage, potentially improving cognitive function and reducing the risk of age-related cognitive decline.
- Antioxidant Properties: Hazelnuts are abundant in antioxidants, which help protect the body against free radical damage, reducing the risk of chronic diseases.
- Fiber Content: Hazelnuts provide a good source of dietary fiber, which aids digestion, promotes gut health, and helps regulate blood sugar levels.
Identifying the Perfect Time to Harvest Hazelnuts
Knowing when to harvest hazelnuts is crucial for maximizing flavor and ensuring proper storage. Several indicators will help you determine the optimal time to begin your harvest:
- Color Change: The most obvious sign is the color change of the husk. As the hazelnuts mature, the green husk surrounding the nut will begin to turn light brown or tan.
- Natural Drop: Mature hazelnuts will naturally begin to fall from the tree. This is a reliable sign that the nuts are ready for harvest.
- Nut Condition: Open a few husks and examine the nuts. They should be plump, full, and have a rich, dark brown color. Avoid harvesting nuts that are shriveled, discolored, or show signs of insect damage.
A Step-by-Step Guide to Harvesting Hazelnuts
Harvesting hazelnuts is a relatively straightforward process, but following these steps will ensure a successful and efficient harvest:
- Prepare the Area: Clear the ground beneath the hazelnut trees of any debris or weeds. This will make it easier to collect the fallen nuts.
- Gather Fallen Nuts: Collect the hazelnuts that have fallen from the tree. You can use a rake or simply pick them up by hand.
- Shake the Branches (Optional): If you want to expedite the harvest, you can gently shake the branches of the tree to dislodge any ripe hazelnuts. Be careful not to damage the tree.
- Collection Method: Use baskets, buckets, or bags to collect the harvested hazelnuts.
- Curing Process: Spread the harvested hazelnuts in a single layer on a screen or tray in a well-ventilated area for several weeks to cure. This allows them to dry properly and reduces the risk of mold.
- Storage: Once the hazelnuts are fully cured, store them in an airtight container in a cool, dry, and dark place.
Common Mistakes to Avoid During Hazelnut Harvesting
Even experienced hazelnut growers can make mistakes. Avoiding these common pitfalls will help ensure a successful harvest:
- Harvesting Too Early: Picking hazelnuts before they are fully mature will result in bland flavor and poor storage quality.
- Neglecting to Cure: Failure to properly cure hazelnuts can lead to mold growth and spoilage.
- Improper Storage: Storing hazelnuts in a warm, humid environment will shorten their shelf life and increase the risk of spoilage.
- Ignoring Pests: Regularly inspect your hazelnut trees for signs of pests and diseases. Take appropriate measures to control infestations and prevent damage to your crop.

Do I need to prune my hazelnut trees?
Yes, pruning is important for maintaining the health and productivity of hazelnut trees. Pruning helps to remove dead or diseased wood, improve air circulation, and encourage new growth.
How often should I fertilize my hazelnut trees?
Hazelnut trees benefit from regular fertilization, especially in the spring. Use a balanced fertilizer formulated for nut-bearing trees. Soil testing can help determine specific nutrient needs.
What are the different varieties of hazelnuts?
There are many different varieties of hazelnuts, each with its own unique characteristics. Some popular varieties include ‘Barcelona’, ‘Jefferson’, and ‘Yamhill’.
