Common Harvesting Techniques for Lingonberries

Lingonberries, scientifically known as Vaccinium vitis-idaea, are small, red berries that grow on low evergreen shrubs in cold regions of the Northern Hemisphere. These berries are highly valued for their tart flavor and are commonly used in various culinary preparations, such as jams, sauces, and desserts. Harvesting lingonberries requires careful techniques to ensure optimal yield and quality. Here are some common harvesting techniques for lingonberries:

1. Handpicking

Handpicking is the most common and traditional method of harvesting lingonberries. Skilled harvesters carefully pluck the ripe berries from the shrubs using their fingers or small handheld tools. This technique allows for selective picking of only the fully ripe berries, ensuring the best quality harvest.

2. Raking

In commercial lingonberry cultivation, raking is often employed to harvest a larger quantity of berries efficiently. Specialized rakes or combs with closely spaced teeth are used to gently comb through the shrubs, dislodging the ripe berries. The berries fall onto a collection sheet or directly into containers placed beneath the shrubs.

3. Mechanical Harvesting

In large-scale lingonberry production, mechanical harvesting techniques are sometimes utilized to increase efficiency. Mechanical harvesters equipped with rotating brushes or vibrating rods gently shake the shrubs, causing the ripe berries to fall onto conveyor belts or collection trays. This method allows for rapid harvesting of a significant quantity of berries but requires careful calibration to avoid damaging the shrubs or collecting unripe berries.

4. Vacuum Harvesting

Vacuum harvesting is a relatively new technique used in lingonberry cultivation. It involves the use of vacuum suction to remove the ripe berries from the shrubs. A vacuum harvester is maneuvered over the plants, creating a controlled airflow that detaches the berries from the stems. The berries are then collected in a container attached to the harvester. This method is gentle on the plants and allows for efficient harvesting with minimal damage to the berries.

It is important to note that lingonberries have a relatively short harvesting window, typically lasting for a few weeks in late summer or early autumn. Harvesting should be timed carefully to ensure that the berries are at their peak ripeness, as this directly affects their flavor and quality.

By employing these common harvesting techniques, lingonberry growers can ensure a successful harvest and provide consumers with delicious and nutritious berries.
