Lingonberries, often referred to as “cowberries” or “lumberberries,” are small, tart red fruits native to the northern regions of North America, including Minnesota. With their vibrant color and tangy flavor, these berries are not only a delightful addition to various dishes but also hold significant cultural and medicinal importance. If you’re considering growing lingonberries in Minnesota, this comprehensive guide will take you through everything you need to know—from selecting the right variety to harvesting your first crop.
Lingonberries (Vaccinium vitis-idaea) are part of the Ericaceae family and are closely related to cranberries and blueberries. They thrive in acidic soils, making them well-suited for Minnesota’s diverse ecosystems. Apart from their culinary uses—like jams, jellies, and sauces—lingonberries are known for their high antioxidant content and potential health benefits, including anti-inflammatory properties.
When it comes to growing lingonberries, the first step is selecting the appropriate variety. There are several cultivars available:
Red Pearl: This is one of the most common varieties grown in home gardens. It produces bright red berries with a sweet-tart flavor.
Erntedank: Known for its high yield and resistance to diseases, this variety can be an excellent choice for those looking for more robust plants.
Koralle: This variety is celebrated for its large fruit size and consistent production. It’s perfect for gardeners who want substantial harvests.
For optimal growth, source your plants from local nurseries or reputable online retailers that specialize in hardy berry plants. Always check that the variety is suited for Minnesota’s climate and soil conditions.
Lingonberries thrive in acidic soils with a pH between 4.5 and 5.5. Here are some tips on preparing your soil:
Testing pH: Before planting, test your soil’s pH with a simple soil test kit available at garden centers or online.
Amending Soil: If your soil is not acidic enough, you can amend it using sulfur or peat moss. Incorporating pine needles or sawdust can also help lower the pH.
Drainage: Ensure that your planting area has excellent drainage capabilities as lingonberries do not tolerate standing water.
Lingonberries prefer full sun to partial shade. Ideally, they should receive at least six hours of sunlight daily. When selecting a location in your garden, consider areas that are shielded from strong winds but still receive ample sunlight.
Lingonberries grow as low evergreen shrubs and can spread over time. When planting:
Spacing: Allow at least 18 inches between plants to give them room to grow without overcrowding.
Planting Depth: Plant lingonberry shrubs at the same depth they were growing in their nursery containers; burying them too deep can lead to root rot.
The best time to plant lingonberries in Minnesota is during early spring or late fall when temperatures are mild. Follow these steps for successful planting:
Digging Holes: Prepare holes that are twice as wide as the root ball of your lingonberry plant.
Incorporating Organic Matter: Mix organic matter such as compost into the backfill soil to aid in drainage and provide nutrients.
Watering: After planting, water thoroughly and keep the soil moist (but not soggy) as the plants establish themselves.
