Lingonberries are in the genus Vaccinium and are closely related to highbush blueberries (Vaccinium corymbosum L.) and cranberries (V. macrocarpum L.). Lingonberries are well-suited to cooler climates and can be expected to do well in regions where blueberries and cranberries are productive.

Lingonberries are native to Scandinavia, Europe, Alaska, the U.S., Canadian Pacific Northwest, and northeastern Canada, but are not widely cultivated. Known commercial lingonberry acreage is only 71 acres worldwide. Lingonberry production is a relatively new endeavor in the Pacific Northwest.

Plant names

The lingonberry is known by many names throughout the world: lingberry, lingen, lingonberry, lingon and puolukka (Finland); alpine cranberry, airelle dʼIda and airelle rouge (France); mirtillo rosso (Italy); dry-ground cranberry, foxberry, fox berry, graines rouges (Quebec); moss cranberry, mountain cranberry, northern mountain cranberry and partridgeberry (elsewhere in Canada); preiselbeern, shore cranberry and Tytlebaer (Germany); berris and cowberry (England); Kokemomo (Japan); and linberry, lowbush cranberry, red berry, red whortleberry and rock cranberry (Alaska).

Section anchor "botanical-description"

Botanical description

The genus Vaccinium consists of 450 species, including lingonberry, blueberry, and cranberry. Lingonberry is a perennial, woody, evergreen, acid-loving shrub. It is low-growing and spreads by below-ground stems called rhizomes. The fruit are relatively small (0.17–0.45 gram per fruit), bright red to dark red, strong-flavored, and tart. They are nutritious and rich in antioxidants, anthocyanins, and flavonoids.

There are two general types of lingonberries: wild and European. The wild lingonberry is Vaccinium vitis-idaea Linnaeus var. minus (Lodd) Hulten. These plants are short (less than 7 inches, or 18 centimeters, tall) and have single blooms. The leaves are ovate, 0.4–1 inch (1–2.5 centimeters) long, alternate, leathery, and evergreen. They have a dark green upper surface and a light green undersurface (Figure 1).

The European, or cultivated, lingonberry is Vaccinium vitis-idaea Linnaeus (Hulten). These plants are 2–16 inches (5–40 centimeters) tall and have white or light pink bell-shaped flowers (Figure 2). There are five to nine glossy evergreen leaves per branch, and leaves can be either light or dark green. The branches are 1–2 inches (3–4 centimeters) long (Figure 3).

Kinnikinnick (Arctostaphylos uva-ursi) and lingonberries are easily confused due to their similar leaf structure and berry size (Figure 4). Both plants are native to the Pacific Northwest. Kinnikinnick has red berries, 5–8 mm, while lingonberry fruits are bright red and 7–11 millimeters. Huckleberries, another similar plant, have blue-purple fruit, 8–11 millimeters, while cranberries have bright red fruit, 8–12 millimeters.

Section anchor "production-areas"

Production areas

Wild lingonberries are found in more than 24 countries and are indigenous to the sandy, northern, temperate, boreal forests of Alaska, Canada, Scandinavia, Sweden, Finland, and Russia. Currently, Oregon, Washington, and British Columbia have more than 17 acres in commercial production, which is approximately one-quarter of the commercial acreage worldwide. Other areas of North America, such as Wisconsin, Vermont, and Maine, also have very small areas in production.

Section anchor "climate"

Climate

Lingonberries are hardy plants and can survive freezing temperatures. However, when freezing temperatures or frost occur during flowering or fruiting, berry loss can be up to 50%. In Europe, plants with ripe fruit have been noted to survive temperatures as low as 28°F (minus 2°C). Those with green fruit have survived at 27°F (minus 3°C).

Plants perform well in maritime climates, and in Oregon and Washington, they have survived temperatures as low as 2°F (minus 17°C). If there is no snow cover and temperatures drop below 10°F (minus 12°C), protect plants with straw mulch, overhead irrigation, or floating row covers.

Section anchor "bloom"

Bloom

Lingonberries flower on 1-year-old growth (the previous yearʼs growth). They are known as branch tip bloomers. There are two bloom periods: March to April and July to August. The fruit ripens in mid-August and mid-October, respectively.

Section anchor "pollination"

Pollination

Lingonberries need pollination from a pollinizer cultivar to produce good-size berries. Pollinizer cultivars tend to be lower-yielding, but they enable high-yielding cultivars to be very productive. Pollinizer cultivars are needed for both spring and summer bloom periods. Plant 10 percent of the field with pollinizer cultivars to achieve the best pollination and highest yield (Figure 5). Red Pearl and Sussi are two commonly used pollinizer cultivars.

Bees, flies, bumblebees, butterflies, and other flying insects are important pollinators. Fields should be kept open and in full sun for optimal fruit set. Wind does little to pollinate lingonberry flowers, and high winds or heavy rain can hamper pollination. Frost during the blossom period can damage flowers and prevent pollination and fruit set, even with temperatures as mild as 28°F (minus 2°C).

Section anchor "common-uses"

Common uses

Food items/products

Lingonberries can be eaten fresh but are more commonly processed into sweet food products such as jams, jellies, syrups, purées, sauces, fruit juices, and beverage concentrates. Lingonberries are used to make liqueurs, wine, fruit leather, and dried fruit. They often are added to mixes with raisins, pickled, or added to chocolates, muffins, pies, pancakes, rolls, tarts, cookies, ice cream, and yogurt. Lingonberries are mixed with other berries, especially cranberries.

Food coloring

Lingonberries have a relatively high anthocyanin content. Anthocyanin is a source of the purple, blue, and red colors in many horticultural crops. With the reduced availability of artificial food colors, there is interest in using water-soluble plant pigments such as anthocyanin for food colors.


Medicinal

Many species of Vaccinium (Ericaceae family), including lingonberry, bilberry, and blueberry, are being studied for their rich flavonoid content (anthocyanins, flavonols, and proanthocyanidins). These compounds are being studied for their possible anticarcinogenic and antioxidant activities and other nutraceutical properties. Lingonberries also are very high in vitamin C. Leaves and stems contain arbutin, which is used by pharmaceutical companies for skin care products. Lingonberries also are used to make infusions and herbal teas.

Section anchor "cultivars"

Cultivars

Currently, there are 16 cultivars (14 high-yielding producers and two pollinizers) and five numbered selections planted in the Pacific Northwest.

  • Ammerland. Vigorous and high-yielding. One of the oldest available cultivars, but very little commercial acreage has been planted with this cultivar. Plants grow 12–14 inches (30–36 centimeters) tall. Berries are medium-size to large (0.28 gram). Country of origin: Holland.

The plants are 4–8 inches (10–20 centimeters) tall with medium green leaves. The berries are medium in size (0.27 gram), light red, and grow on the branch tip. Country of origin: Norway.
  • Splendor. Plants yield moderately after the second year and heavily after the third year. A precocious, moderately vigorous cultivar that has somewhat frost-tolerant flowers and fruit buds. Average plant height is 6–10 inches (15–25 centimeters), and foliage is medium green. The berries are small (0.24 gram) and grow on the branch tip. High in anthocyanins. Country of origin: U.S.

Pollinizer cultivars

Pollinizer cultivars tend to have moderate yields and average fruit quality. Fields generally are planted to include 10 percent of a pollinizer variety to ensure good pollination for the higher-yielding varieties.

  • Red Pearl. Low-yielding but heavily planted due to its suitability as a pollinizer. Plants have an upright, vigorous growth habit, are 13–15 inches (33–38 centimeters) tall, spread nicely, and have dark green foliage. Berries are small to medium-size (0.18 gram), bright red, and grow on the branch tip. Introduced to the U.S. by Elden Stang in 1983. Country of origin: Holland.
  • Sussi (Patent Number VF 846.941220). Moderate yielding in mid-October. A vigorous plant with a spreading habit. Plants are of medium height, 7–10 inches (18–25 centimeters), with dark green foliage. Fruit ripening is uniform. Berries are small to medium-size (0.26 gram) and grow on the branch tip. A nice ornamental plant with some resistance to Phytophthora root rot. Country of origin: Sweden.

Numbered cultivars

Five numbered cultivars were developed in Balsgard, Sweden, and planted in test plots in Oregon in 2002. Average berry weights for these cultivars are: 8726-8 (0.31 gram), 8739-8 (0.24 gram), 87102-3 (0.22 gram), 8723-10 (0.34 gram), and 8724-49 (0.25 gram). Country of origin: Sweden.

Section anchor "yield"

Yield

A healthy lingonberry planting can be expected to be productive for 20 years or more. Yields from commercial fields (5- to 8-year-old plants) in the U.S. range from 2–15 tons per acre (Table 1). These yields are greater than in Germany (0.5–6 tons per acre) or Sweden (1–3.6 tons per acre). In cultivar trials in Fall Creek, Oregon, the average cultivar yield was 6.6 tons per acre, and yields ranged from 2 tons per acre for Red Pearl to 15 tons per acre for Erntesegen (Figure 6). With good management, lingonberry yields in the Pacific Northwest should be comparable to or better than many small fruit yields. In comparison, blueberries average 4.5–6 tons per acre, strawberries 3.5–4.5 tons per acre, and cranberries to 8 tons per acre.

Table 1. Yield of lingonberries produced in Europe and Oregon (U.S. tons per acre and tons per hectare).

Country U.S. tons/acre Tons/hectare
Germany (range) 0.5–6.0 1.2–14.8
Sweden (range) 1.0–3.6 2.5–8.9
United States
Low yield 2.3 5.8
Medium 6.6 16.4
High 15 35.7

Source: R. Penhallegon, ISVC 2004.

Weights of individual berries range from 0.17 gram to 0.45 gram for varieties grown in Fall Creek, Oregon (Figure 7). Most cultivars produce larger berries in the fall than in the summer (Figure 8). Erntesegen, Koralle, Linnea, and Sanna are exceptions; they produced larger berries in the summer than in the fall. Brix, a measure of the amount of soluble sugars in the fruit, was highest for the cultivar Erntesegen (13.9 °Brix) and lowest for Erntekrone (10.2 °Brix) (Figure 9).

Section anchor "cultural-management"

Cultural management

Soil type

Lingonberries prefer a light, well-drained soil such as a sandy loam, a well-drained loam, or a silty loam. Determine the type of soil in your field by referring to the county soil survey or send a sample to a soil lab for analysis.

Oregon and Washington growers have planted lingonberries on raised beds to improve water drainage and decrease the risk of root rot. Raised beds should be 4–8 inches (10–20 centimeters) high. If necessary, install field tiles or rip the soil to improve drainage prior to planting. For heavier soils such as deep clay, incorporate organic matter such as compost or a cover crop prior to planting to help improve drainage and increase the organic matter content.

Lingonberries are most productive in soil with an organic matter level of 2%–6% in the top 3–6 inches and with a soil pH of 4.3–5.5. If the soil pH is too high, use elemental sulfur to lower it. (See Acidifying Soil for Crop Production West of the Cascade Mountains, EM 8857-E). Lingonberries are very sensitive to high salt concentrations, especially sodium (Na) and chloride (Cl). High levels of calcium (Ca) also can have a toxic effect on the plants.

Propagation

Lingonberries are most commonly propagated by micro-propagation (also known as tissue culture) and stem cuttings. As production needs increase, rhizome divisions and seedlings also are becoming more available for commercial planting. Stem cuttings and rhizome divisions can be rooted during the spring or late summer and transplanted into the field the following spring or fall. Seeds can be sown in a greenhouse. Transplant 1- or 2-year-old seedlings to the field in the spring or fall.

Each of these techniques has limitations. For example, plants started from stem cuttings may not develop vigorous rhizome growth and may have limited plant spread and yield. Plants started by rhizome division can spread pathogens, and seedlings may not be true to parent stock. Two- to 3-year-old lingonberry plants (propagated by one of the methods described above) also can be purchased. These older plants cost more but can reduce total plant establishment costs and the time between planting and first harvest. The cost of rooted, field-ready 1–2 year old plants is $1–$3 per plant, and the cost of 2–3 year old plants is $3–$7 per plant.

Planting

Plant lingonberries in the spring or fall. Plant roots 2–3 inches deep. If planting seedlings, set the plant root system just below the top of the soil surface.

Set plants in a single row down the center of the raised bed. Space bed centers 24–36 inches (61–91 centimeters) apart and space plants 8–18 inches (20–46 centimeters) apart within the row (Figure 10). Plants spread through rhizome growth and will cover the bed by the fourth or fifth year. At planting, populations are 5,800–10,900 plants per acre, and the average recommended planting density is 8,700 plants per acre.

Mulches

Various organic mulches can be used with lingonberries, including sawdust, compost, chipped yard debris, composted or fresh grass seed straw, leaf or bark mulch, wood chips, manure, mint compost, and pine forest duff (Figures 11 and 12). Add about 10 tons (4 inches) of organic material per acre to be incorporated into the soil as a soil amendment before planting. After planting, add an additional 4–6 inches of organic-based mulch around the base of the plants. Replenish the mulch every 3–6 years or as needed.

Fertility

Do not apply high rates of fertilizer to lingonberries. Overapplying fertilizers reduces yield and can cause plant dieback. Plant dieback symptoms are similar to those caused by fungal disease (Phytophthora cinnamomi or root rot); the leaves turn brown or black. Use only chloride-free fertilizers, as chloride salts severely damage plants.

Use nitrogen in the ammonium form such as urea (less acidifying) or ammonium sulfate (acidifying). In years 1–5, apply 20–40 pounds (10–20 kilograms) of nitrogen per acre each year. After the fifth year, apply 40 pounds (20 kilograms) of nitrogen per acre each year. Nitrogen rates above 60 pounds (27 kilograms) per acre can cause excess vegetative growth and reduce flowering and yield. Varieties seem to differ in sensitivity to fertilizer applications. Koralle and Red Pearl were more sensitive to high fertilizer application rates than other varieties.

Irrigation

Overhead sprinklers or drip (trickle) irrigation can be used in lingonberry production. Drip irrigation is the preferred method. Bury drip lines in the raised beds before planting. Apply irrigation throughout the first summer to improve plant establishment and reduce sunburn. Test irrigation water for pH, chloride (Cl), sodium (Na), and calcium (Ca). Lingonberries are sensitive to chloride and sodium.

Irrigate plants at a rate of about 0.5–0.75 inch (1–2 centimeters) of water every week. Plants thrive when irrigation practices are correctly targeted to the soil environment. In heavier soils, avoid over-watering, which increases the risk of Phytophthora (root rot) or Pythium (damping off). In new field plantings in Oregon, the variety Koralle showed moderate to severe dieback due to root rot when it was planted in heavy soils and irrigated at high rates, while in other fields this variety died during the first 2 years due to lack of irrigation.

Do not allow the soil to dry out completely between irrigations. Dry soil increases the salt concentration in the soil water, and lingonberries are very sensitive to even modest salt concentrations.

Pruning

No pruning is recommended in the first 4 or 5 years after field planting. After the plants are 5 years or older, you can mow alternate rows to a height of 2 inches (5 centimeters). Mow alternate rows every 3–6 years to increase shoot density and stimulate vigorous, unbranched, 1-year-old growth, which will increase the number of fruiting stems. There is no information at present on the best way to prune lingonberries.

Section anchor "pests"

Pests and pest management

Weeds

Weed control is critical during the first 3 years of field establishment. Weed control methods include hand weeding and mechanical cultivation. Lingonberries form roots very near the soil surface and therefore are susceptible to damage from deep cultivation.

To control weeds between rows, plant a grass sod between the rows, and mow periodically to prevent grasses from seeding. Within the row, apply 4–8 inches (10–20 centimeters) of mulch to help prevent weed growth. Lingonberries produce an allelopathic compound that helps reduce germination of annual weeds in the rows. Currently, there are only a few herbicides labeled for use in lingonberries.

Insects

Few major pests have been observed in lingonberry fields. In Oregon and Washington, the Western spotted cucumber beetle (Diabrotica undecimpunctata Fabr.), the Western striped cucumber beetle (Diabrotica trivittala Mann.), and the oblique-banded leafroller (Choristoneura rosaceana Harris.) have been found feeding lightly on lingonberry leaves after grass seed fields were harvested. The obscure root weevil (Sciopithes obscurus Horn.), a very common pest that feeds on blueberry leaves, has not been seen in any lingonberry fields. In Newfoundland, lingonberry fruitworm (Grapholita libertina Heinrich.) burrows into the lingonberry fruit, but the larvae are not observed until the fruit is processed. See the Pacific Northwest Insect Management Handbook for information on insect control.

Diseases

Lingonberries are very susceptible to several diseases, including various pathogenic fungi that have been found in association with leaf spots and twig blights in Oregon. Allantophomopsis lycopodina (Hohn.) Carris, or black rot, has been found on the cultivars Erntesegen, Erntekrone, and Koralle. Phomopsis columnaris, or upright dieback, has been found on Koralle and can result in plant death. Coleophoma empetri (Rostrip) Petrik, or ripe rot, has been found on Red Pearl. Rhizoctonia sp. has been found on Koralle. Phytophthora citricola Sawara, or root rots, also have been found in lingonberries.

In 2000, lingonberry twig die-back Phomopsis columnaris (also known as lingonberry twig blight) was identified as a new disease in Oregon (Farr et al., 2000). The symptoms of this fungal pathogen include soft, light brown rot or “sunburned” berries and premature fruit drop.

Because several pathogens affect lingonberries, and because their symptoms are somewhat similar, laboratory analysis is necessary to confirm which pathogen is present. Due to susceptibility of lingonberries to fungal infection, it is important to start with disease-free plants in the field. See the Pacific Northwest Plant Disease Management Handbook for information on disease control.

Sudden oak death (Phytophthora ramorum, or SOD) has been tested on lingonberries and was positive. However, no SOD has been found in any lingonberry plant materials in growersʼ fields.

Additional potential problems

Lingonberries are closely related to blueberries and cranberries, and there is some concern that pests in these two common crops also may appear in lingonberries. Such potential problems include blueberry scorch and shock. These pests have not been found on lingonberries, but growers are advised to watch for symptoms and send potentially infected plants to a laboratory for disease diagnosis.

Vertebrate pests

Moles are attracted to worms feeding in high organic matter soil. Moles do not damage plants directly, but tunneling beneath and around plants causes roots to dry out and dislodges plants. Traps are the most effective method of controlling moles. Gophers also can be a problem in lingonberry fields if gopher and weed populations are high. Voles (field mice) commonly are found in the grass area between beds. Regular mowing between beds will suppress vole populations.

At harvest time, mice feed on ripe berries, causing fruit losses. Birds, especially robins and finches, can also be a nuisance as they feed on ripening berries. Bird damage occurs more frequently in the fall crop than in the summer crop. In the summer, birds have a larger selection of food sources than in the fall, including ripe blackberries, blueberries, and raspberries. To discourage birds, use netting, “bird-eye” balloons, scare and distress recordings, and mylar flash tape.

Deer, bear, and moose browsing can substantially damage new plantings and reduce plant establishment. Fencing will help prevent animals from entering the field. Contact your local Extension office for more information and current techniques for controlling vertebrate pests.

Section anchor "harvesting"

Harvesting

Berries can be harvested when they are light red to dark red. If berries are harvested too early, when they are still somewhat green, they can be bitter. However, lingonberries ripen to a dark red color after being stored for several weeks under refrigeration. Research is underway to use soluble solids as a way to determine the best time to harvest lingonberries.

Summer-crop berries will fall off the plant by the fall harvest period. If harvested in the fall, they will be overripe and will not store well.

Frost just prior to lingonberry harvest does not harm fruit on the plants, but a prolonged period of freezing temperatures prior to harvest will cause crop loss. Lingonberries are most commonly harvested by hand with berry rakes, similar to those used for lowbush blueberries or dryland cranberries (Figure 13). Mechanical harvesters used for lowbush blueberries and cranberries can be converted into lingonberry harvesters. A mechanical harvesting device was developed by C. von Zabeltitz, at the Institute of Horticulture Engineering at the University in Hannover, Germany. In Minnesota, mechanical dryland cranberry pickers are available through the Furford Picker Company. In Nova Scotia, Douglas Briggs developed a lowbush blueberry picker, and the Maine Blueberry Equipment Company has developed a lowbush blueberry mechanical harvester.

For fresh-pack markets, the stem must be removed from the lingonberry. Stems can be removed with a blueberry stemmer.

Section anchor "postharvest"

Postharvest

Lingonberries contain high levels of benzoic acid, which naturally provides a long shelf life. Picked and cleaned berries for the fresh market can be kept up to 3–5 weeks prior to shipping. Store fresh berries under refrigeration at temperatures of 32–45°F (0–7°C). Refrigeration will maintain the “fresh” quality of the berries as long as the berries were not overly ripe when they entered storage. Overripe berries do not store well and should be marketed or processed immediately.

Berries can be stored in a freezer for many months. Individually quick frozen (IQF) berries commonly are used in value-added products such as jams, jellies, and juice concentrates.

Section anchor "marketing"

Marketing

Fresh berries packed in baskets sell on the retail market at a price of $2.50–$7 per pound. In 2002, berries for jam sold for $0.77–$1.25 per pound ($0.35–$0.57 per kilogram) in Poland, Russia, and Finland, and $2.00 per pound ($0.91 per kilogram) in Oregon.

Worldwide, 10% of the crop is sold for juice concentrate. Lingonberries contain about 30 percent less water than cranberries and therefore produce a more concentrated juice. This characteristic makes lingonberries very attractive to processors.

Currently, lingonberries are imported into the U.S. (146,827 pounds in 2003), demonstrating the demand for this fruit and the market potential.
