How Do You Know When To Pick Hazelnuts

You know when to pick hazelnuts by watching for a few key signs that signal they’ve reached full maturity.
 
Knowing when to pick hazelnuts comes down to timing, color, and how easily the nuts release from their husks.
 
If you’ve ever stood by your hazelnut tree wondering if it’s the right moment, you’re not alone.
 
The good news is that there are clear indicators you can look for to know exactly when to pick hazelnuts for the best flavor and texture.
 
Picking them too early means you’ll get bland, underdeveloped kernels, while waiting too long can lead to nuts that fall to the ground and get eaten by wildlife.
 
In this post, we’ll explore the telltale signs for when to pick hazelnuts, how to test for ripeness, and tips for harvesting and storing them properly.
 
Let’s dig into the details so you can enjoy a perfect harvest every single season.
 

When to Pick Hazelnuts: The Key Ripeness Signals

When to pick hazelnuts is ultimately determined by how the nuts look and feel on the tree or shrub.
 
Hazelnuts don’t all ripen at the exact same time, so you’ll need to check your plants regularly over a few weeks.
 
Here are the primary signals that tell you it’s time to pick hazelnuts:
 

1. The Husk Turns Brown and Papery

The most obvious sign of when to pick hazelnuts is the appearance of the husk that surrounds each nut.
 
When hazelnuts are immature, the husk is green, fleshy, and tightly wrapped around the shell.
 
As the nuts mature, this husk begins to dry out, turning a light brown or tan color.
 
It also becomes papery and starts to pull away from the shell, making it easier to see the nut inside.
 
If you notice the husks looking crispy and slightly open, that’s a strong clue that it’s time to pick hazelnuts.
 
Wait until most of the husks on your tree show this brown coloration before you start harvesting.
 

2. The Shell Hardens Completely

Another reliable way to determine when to pick hazelnuts is by feeling the shell’s hardness.
 
Gently squeeze a nut between your thumb and forefinger while it’s still in the husk.
 
If the shell is still soft, pliable, or easily dented, the hazelnut isn’t ready yet.
 
A mature hazelnut shell will feel rock solid and resistant to pressure.
 
When you pick hazelnuts at this stage, the kernel inside has had enough time to fill out the shell completely.
 
You can also shake the nut near your ear; if you hear the kernel rattling inside, that means the nut has shrunk slightly as it dried, which is a good sign of maturity.
 

3. The Nuts Start Falling to the Ground

Nature gives you a clear signal for when to pick hazelnuts: they begin dropping on their own.
 
In many regions, hazelnuts naturally fall from the tree from late summer through early autumn, typically between August and October depending on your climate.
 
If you see a few nuts on the ground beneath your tree, that’s a sure sign the rest are nearly ready.
 
You can still pick hazelnuts directly from the branches even after some have fallen, as long as they show the other signs of ripeness.
 
However, don’t leave them on the ground for too long, because squirrels, birds, and insects will quickly find them.
 

How to Test if It’s Time to Pick Hazelnuts

If you’re still unsure about when to pick hazelnuts, there’s a simple test you can do right in your orchard.
 
This method takes the guesswork out of harvesting and ensures you don’t pick hazelnuts too early or too late.
 

1. The Cut Test for Kernel Development

Take a sample hazelnut from your tree and crack it open with a nutcracker.
 
Look at the kernel inside; it should fill the shell almost completely and have a creamy white or light tan color.
 
If the kernel is small, shrunken, or has a jelly-like texture, it’s not mature, so it’s not yet time to pick hazelnuts from that tree.
 
If the kernel is firm and snaps cleanly when you bite it, you’re good to go.
 
Checking a few nuts from different parts of the tree gives you a better overall picture.
 

2. The Float Test

Another handy trick is the water float test, which you can do after you pick hazelnuts to separate the good ones.
 
Place a handful of nuts in a bowl of water; mature nuts that are ready will sink to the bottom.
 
Nuts that float are usually hollow, dried out, or damaged by pests, so you can discard those.
 
While this test doesn’t tell you exactly when to pick hazelnuts initially, it confirms that your harvest was timed well.
 

3. Monitor the Calendar and Weather

Hazelnuts typically need about 140 to 160 days from flowering to reach maturity, so you can track this timeline.
 
If your tree bloomed in early spring, then late summer to early fall is usually the window for when to pick hazelnuts.
 
Cooler, wetter summers can delay ripening, while hot, dry weather tends to speed it up.
 
Keep an eye on local forecasts, as heavy rain or wind right before harvest can knock nuts down prematurely.
 
Planning around these seasonal patterns helps you pick hazelnuts at their peak.
 

Best Practices When You Pick Hazelnuts

Once you’ve confirmed it’s time to pick hazelnuts, how you harvest them matters just as much.
 
Using the right technique protects the tree and ensures your nuts stay in top condition for eating or storing.
 

1. Hand-Pick or Use Tarps

For small trees or shrubs, you can simply pick hazelnuts by hand.
 
Twist each nut gently until it separates from the branch, or snip the stem with small pruning shears.
 
For larger orchards, spread a tarp or old sheet under the tree and shake the branches lightly.
 
This encourages ripe nuts to fall onto the tarp without damaging the tree or the nuts themselves.
 
When you pick hazelnuts this way, you collect them all at once without stooping for every single one.
 

2. Dry the Nuts After Harvesting

After you pick hazelnuts, they need a curing period to develop their full flavor and extend their shelf life.
 
Spread the nuts in a single layer, still in their husks, in a dry, well-ventilated area out of direct sunlight.
 
Leave them for two to four weeks, turning them occasionally to prevent mold.
 
Once the husks are completely brittle and the shells rattle when shaken, you can remove the husks and store the nuts.
 
This drying step is essential for tasty, crunchy hazelnuts that last through the winter.
 

3. Store in a Cool, Dry Place

Proper storage keeps your harvest fresh long after you pick hazelnuts.
 
Shelled hazelnuts can last about three months in a cool pantry, or up to a year in the refrigerator.
 
Unshelled hazelnuts store even longer because the shell protects the kernel from air and moisture.
 
Place them in an airtight container or a mesh bag in a cool, dark spot.
 
If you notice any nuts with dark spots or a rancid smell, remove them immediately so they don’t spoil the others.
 

So, How Do You Know When to Pick Hazelnuts?

You know when to pick hazelnuts by checking for brown, papery husks, hard shells, and nuts that begin falling naturally.
 
In addition, cutting open a sample nut to verify the kernel has filled the shell is the most foolproof method.
 
So, how do you know when to pick hazelnuts in your own backyard?
 
You simply combine those visual cues with the calendar and your local weather patterns.
 
Once you see these signs, don’t delay; the window for picking is often just one to two weeks wide.
 
Now that you know exactly when to pick hazelnuts, you can head out to your tree with confidence and enjoy a bountiful, delicious harvest.
 
Happy harvesting, and may your hazelnuts be perfectly ripe and wonderfully crunchy every single time.
