When Are Hazelnuts Ready To Be Picked

Hazelnuts are ready to be picked when the husks turn brown and begin to fall away from the shell.

This usually happens in late summer to early autumn, depending on your local climate and the specific variety you are growing.

If you’ve been checking your tree daily and wondering when are hazelnuts ready to be picked, you’re likely noticing the first signs of that natural separation.

The easiest way to know when are hazelnuts ready to be picked is to watch the ground, because mature nuts will start dropping on their own.

In this post, we’ll explore the best indicators that hazelnuts are ready to be picked, the ideal harvest window, and how to dry and store them properly.

Let’s dive into the details so you can enjoy a perfect harvest every single season.
 

When Are Hazelnuts Ready to Be Picked: Key Signs to Watch

When are hazelnuts ready to be picked depends on a few visual and tactile clues that tell you the nut has reached full maturity.

You don’t need fancy equipment to figure out the right time, just a keen eye and a little patience.

1. The Husk Turns Brown and Papery

The most reliable sign that hazelnuts are ready to be picked is the appearance of the husk that surrounds each nut.

When the nuts are immature, this husk is green, fleshy, and tightly wrapped around the shell.

As the nuts mature, that husk slowly dries out, turns a rich brown color, and takes on a papery texture.

When you see this browning happening across the tree, you can be confident that hazelnuts are ready to be picked soon.

2. The Husk Begins to Split Open

Another clear indicator that hazelnuts are ready to be picked is when the husks start splitting open at the top.

This opening reveals the hard, shiny brown shell of the nut inside.

Once you see that crack, the nuts are in their prime harvest stage.

If you wait too long after this point, the nuts might drop to the ground and become vulnerable to pests or moisture.

3. Nuts Start Falling Naturally

When hazelnuts are ready to be picked, the tree will begin dropping them on its own.

This natural drop is the most foolproof signal you can get.

You can gently shake a branch to test if nuts are loose enough to fall easily.

If they come off without much resistance, then hazelnuts are ready to be picked from that specific branch.

4. The Kernel Has Filled Out the Shell

You can also crack one open to check if the hazelnuts are ready to be picked based on kernel development.

A mature kernel should be plump, creamy white, and completely fill the inside of the shell.

If the kernel is small, shriveled, or has a jelly-like texture, the nuts aren’t ready yet.

Wait another week or two before you start picking hazelnuts from that tree.

The Best Time of Year to Pick Hazelnuts

The exact calendar date when hazelnuts are ready to be picked shifts depending on where you live and what variety you’re growing.

However, there’s a general window that most growers can rely on.

1. Late August Through October

For most regions in the Northern Hemisphere, hazelnuts are ready to be picked between late August and mid-October.

Early-season varieties might be ready in late August, while late-season types hold off until October.

If you’re growing a common European hazelnut, you should start scouting for signs in early September.

Keep an eye on your local weather, as a warm, dry summer can push the harvest earlier.

2. Check the Growing Zone’s Frost Date

Your specific growing zone plays a big role in determining when hazelnuts are ready to be picked.

In warmer climates, the nuts mature faster and you might start harvesting in late summer.

In cooler northern zones, you’ll likely need to wait until the end of September or even early October.

Just be sure to pick hazelnuts before the first hard frost hits, as freezing can damage the nuts and ruin their flavor.

3. Harvest in Two or Three Rounds

Keep in mind that not all hazelnuts are ready to be picked at the same time, even on a single tree.

The nuts on the outer, sunnier branches tend to mature faster than those shaded in the middle.

Plan to harvest in multiple passes over a couple of weeks.

Check the tree every few days and pick only the nuts that are showing clear signs of readiness.

How to Pick Hazelnuts Without Damaging Them

Once you’ve confirmed that hazelnuts are ready to be picked, you want to handle them with care.

Rough handling can crack the shells or bruise the kernels, which shortens their storage life.

1. Shake the Branches Over a Tarp

The most efficient way to pick hazelnuts is to spread a clean tarp or sheet under the tree.

Then gently shake the branches so the ripe nuts fall onto the tarp.

This method is quick and prevents you from having to pick each nut by hand.

Just remember that only the nuts that are ready will fall, leaving the immature ones to develop further.

2. Hand-Pick the Stubborn Ones

Some hazelnuts that are ready to be picked might still cling tightly to the branch.

For these, simply twist them gently until they release from the stem.

Avoid pulling too hard, as this can strip off bark and damage next year’s fruiting spurs.

It’s better to leave a slightly stubborn nut on the tree for a few more days than to harm the branch.

3. Collect Fallen Nuts Quickly

If you notice nuts on the ground, these hazelnuts are ready to be picked up immediately.

However, don’t leave them sitting on the soil for too long.

Ground moisture can seep into the shells and cause mold to develop.

Gather fallen nuts at least every two to three days during the peak harvest season.

Drying and Storing Hazelnuts After Picking

After you’ve determined that hazelnuts are ready to be picked and have collected them all, the work isn’t quite done.

Proper drying is essential to bring out the full flavor and make the nuts last for months.

1. Dry the Nuts in a Single Layer

Spread your freshly picked hazelnuts in a single layer on a screen, wire rack, or shallow tray.

Place them in a dry, well-ventilated area out of direct sunlight for about two to three weeks.

Stir them every few days to promote even airflow.

You’ll know they’re completely dry when the kernels rattle inside the shells when shaken.

2. Store in a Cool, Dark Place

Once dried, hazelnuts are ready to be stored in a breathable container like a mesh bag or a paper sack.

Keep them in a cool, dark, and dry spot with temperatures around 50-60°F (10-15°C).

In these conditions, in-shell hazelnuts can stay fresh for up to a year.

For even longer storage, you can freeze shelled kernels for up to two years.

So, When Are Hazelnuts Ready to Be Picked?

Hazelnuts are ready to be picked when their husks turn brown, start splitting open, and the nuts begin falling from the tree on their own.

The general harvest window falls between late August and October, but you should always rely on the physical signs rather than the calendar alone.

If you’re asking yourself when are hazelnuts ready to be picked, just look for that browning husk and give the branch a gentle shake.

Enjoy the process, and before you know it, you’ll be cracking open perfectly ripe hazelnuts that taste far better than anything from the store.

Happy harvesting, and here’s to a bountiful nut crop this season.
