If you’re growing almond trees in your backyard or farm, you may wonder when it’s the right time to harvest the nuts. Almonds are delicious, nutritious, and versatile nuts that can be enjoyed as a snack or used in various recipes.

However, picking almond at the wrong time can affect their quality, flavor, and shelf life. Here are some tips for determining when to pick almonds.

Almond Maturity

Before picking almonds, you need to make sure they’ve matured enough to provide the best quality and yield. Almond maturity depends on several factors, including the variety, climate, and soil conditions.

However, a general rule of thumb is to wait until the almond hulls split open or start to dry out. Almond hulls are the outer layer that covers the shell and the nut inside, and they protect the nut from damage and pests.

The almond hulls contain tannins, a bitter and astringent substance that gives the nuts their characteristic flavor and color. When the almond matures, the tannins break down, and the hull becomes fragile and splits.

This process is called “shuck split,” and it happens naturally in late summer or early fall, depending on the region. When the shuck split occurs, the almond kernel inside should be fully formed, plump, and dry. If the kernel is wrinkled or wet, it’s not mature enough.

Shake Test

To check if your almonds are ready to be harvested, you can perform a shake test. This method involves shaking the tree or limbs and observing how many almonds fall to the ground.

If most of the almonds drop with little effort, it’s a sign that they’re mature and ready for harvest. However, if too many immature fruit drops, you may need to wait a little longer or adjust your shaking technique.

When performing the shake test, make sure you’re not using excessive force that can damage the tree or injure the fruit. You can use your hands, a long pole, or a mechanical shaker to vibrate the tree or limbs gently.

If you’re using a pole or a shaker, make sure they’re clean and don’t contain sharp edges that can damage the bark or branches.

Hull Color and Texture

Another way to determine almond maturity is by observing the hull color and texture. As mentioned before, the almond hulls change their appearance when they mature. They can turn from green to yellow, brown, or black, depending on the variety.

Also, the texture can become dry, crispy, and brittle, indicating that the nut inside has dried out and is ready for harvest.

However, not all almond varieties change color when they mature, and some may still have green or pink hulls when they’re ready for harvest.

Therefore, it’s essential to know the specific characteristics of your almond tree and consult with a local expert or extension agent if you’re unsure.

Bird Damage

One of the main challenges of harvesting almonds is dealing with bird damage. Birds, especially crows and ravens, are attracted to the almond orchards and can cause significant losses by pecking the fruit before it’s ready.

This can lead to premature hull split and mold formation, reducing the nut quality and yield.

To prevent bird damage, you can use various methods, such as netting, noise-makers, scarecrows, visual deterrents, and hunting permits.

Each method has its advantages and disadvantages, so it’s essential to choose the one that suits your situation and budget.

Weather Conditions

The weather conditions can also affect almond maturity and harvest time. Late rains or humid periods can delay the shuck split and increase the risk of fungal infections, such as mold and aflatoxin.

Hot and dry weather, on the other hand, can accelerate the fruit drying and shrinkage, reducing the nut size and yield.

Therefore, it’s advisable to monitor the weather forecast and adjust your harvest schedule accordingly. If you expect a prolonged wet or humid period, it may be better to wait a little longer before harvesting.

If you anticipate a heatwave or drought, it’s better to pick the almonds earlier than later.

Conclusion

Harvesting almonds at the right time is crucial to ensure their quality, flavor, and shelf life. Almond maturity depends on several factors, including the variety, climate, and soil conditions.

To determine when to pick almonds, you can use various methods, such as the shake test, hull color and texture, and bird damage prevention. It’s also essential to monitor the weather conditions and adjust your harvest schedule accordingly.
