Arctostaphylos uva-ursi, most often referred to as bearberry, is the perfect edible ground cover for anyone struggling with poor soil or rocky soil conditions in their landscape. Its common name comes from what happens to most of these plants. Apparently bears love the fruit that it produces and will happily consume them in huge volumes in fall as they’re fattening up for the winter. 

This is not limited to bears, either; many types of migratory birds will happily eat the berries. The bright red bearberry is edible for humans as well! You can add visual interest to any home garden with its dark green leaves and pink flowers. 

It’s perennial and is a beautiful, small-leaved ground cover with red berries. The flowers aren’t dramatic, but it looks good as an understory layer around larger shrubs as well as just simply as a cover for a space in your landscape you don’t intend to walk on (it has woody stems that don’t make it suitable for much foot traffic). 

It can perform in both full sun and full shade, although it prefers full sun in most areas. The bearberry is the unsung hero of North America, feeding bears with its berries and acting as a medicinal plant in Native American cultures for centuries.

What is Bearberry?

Arctostaphylos uva-ursi is also known by many other names such as bearberry, kinnickinnick, bear’s grape, sandberry, common bearberry, barren myrtle, mountain box, and hog cranberry. In North America, bearberries have been used extensively by Native American tribes as part of smoking mixtures, dried for tea, as an anti-inflammatory, and as an antiseptic. It also has astringent properties and has been used to wash sores or small wounds. 

Native Area

The plants are native to the circumboreal regions such as Canada, Finland, Russia, and most of the Northern Hemisphere.

The bearberry is an evergreen shrub native to circumboreal regions around the world, such as Canada, Finland, Russia, etc. It prefers northern cold climates and does best in USDA zones 2-6. In the wild, its dark green leaves are mostly found on open slopes, and it thrives in rocky soils. 

Characteristics

Bearberries (Arctostaphylos uva-ursi) are identified by their woody stems, dark evergreen leaves, pink flowers, and eventually bright red berries. They are a slow-growing perennial ground cover that spreads via surface rhizomes. 

It grows in a mat, which makes it beneficial for landscape erosion control and filling in spaces in garden beds. Its urn-shaped flowers attract butterflies and other pollinators to your gardens. In fact, it is the host plant for several butterflies, including the hoary elfin and brown elfin. 

Planting

Place the plants in an area that receives full sun to partial shade and has well-drained, rocky soil.

Choose a well-drained, sandy, or rocky soil for planting bearberries. The location should receive full sun to partial shade. Start by loosening the soil and mixing in organic matter if needed to improve drainage.

Space the bearberries about 12 to 18 inches apart, as bearberry spreads low and wide to form a ground cover. Dig a hole slightly larger than the root ball, place the shrub in the hole, and backfill with soil, pressing gently to remove air pockets.

Water thoroughly after planting.

How to Grow

Bearberries are the perfect species of ground cover if you’re looking for a low-maintenance evergreen that grows in spring and flowers during the summer. It makes a lovely addition to any garden and will require few requirements. It will establish and you’ll be able to enjoy it year after year. 

Light

The plant thrives in full sun and can also tolerate light shade.

Bearberries thrive in full sun, however, they can tolerate light shade. That being said, you’ll get the most growth, flowers, and fruit when you give your bearberry full sun, rather than partial shade.

Water

Water the plants during the first year of growth to get them established.

The bearberry shrub is extremely drought-tolerant once established and may never need to be watered outside of any precipitation that you receive in your garden. For this reason, it is a great landscaping option for low water or xeriscaped gardens. It can tolerate both moist and dry growing conditions, however, it will not tolerate standing water.

During the first year of growth, be sure to water your bearberries to get them established, then you can back off of watering. During the winter it is not necessary to water as it will get all the moisture that it requires from any snowfall. In the mid-spring and summer months, they may require slightly more moisture to deal with the heat. Partial shade also helps with dry soil.

Soil

Plant the ground cover on sandy or rocky soil that is well-draining.

In its native habitat, Arctostaphylos uva-ursi pops up in recently disturbed or rocky soil and tends to fill in slopes where water drainage is abundant. There, it forms a sloping ground cover. Bearberry will tolerate and adapt to many different conditions, including salt in the soil, but it will not tolerate a soil pH outside of its preferred range. It needs well-draining acid soil with a pH between 4.5 and 5.5. 

Since it is salt tolerant and thrives in sandy acid soil, this bearberry makes frequent appearances along coastlines full of salt as well. 

Temperature

The plant develops best in temperatures ranging between 40-77°F (4-25°C).

As mentioned, they do best in USDA zones 2-6 and can tolerate cold winter, fall, and climates. They tolerate the cold so well that seeds can germinate in temperatures as low as 40°F (4°C). 

The bearberry itself does best in a temperature range of 40-77°F (4-25°C). As an evergreen shrub, the dark green leaves are green year-round and do not need protection from frost. They will not, however, tolerate high heat. 

Fertilizing

Provide a nitrogen fertilizer to encourage the plant to spread.

Bearberries can survive in poor soil conditions so fertilizing is not absolutely necessary. However, if you’d like to encourage it to spread in a ground cover fashion more quickly a fertilizer with a slightly higher nitrogen content will do just that. 

You may sacrifice some flowers and fruit in order for them to put on more green growth and spread. It’s important not to fertilize more than once per year as it can easily be overwhelmed. 

Maintenance

Pruning is done to maintain the plant’s shape or to reshape the plant.

Arctostaphylos uva-ursi does not require pruning, but you may choose to prune away dead wood or employ some light pruning to reshape and form the plant and accentuate its dark green leaves. The best time of the year to prune is in late spring or late summer after the bloom time has passed. You’ll want to make sure to leave the flowers to attract the butterflies! 

Propagation

The plants are propagated from seed or stem cuttings.

It can be grown from seed. However, since it is such a slow grower, a much better option for this ground cover is to propagate it from stem cuttings. Fill a pot with sand-dominant soil. New plants can be started by cutting off a stem, dipping it into a rooting hormone powder, and then sticking it into moist sand to root in spring. 

If you’re growing from seed it’s important to keep in mind that they will require cold stratification to form sprouts. It’s recommended to store your seed in the refrigerator for three months before planting it out in the garden. Alternatively, you can sow them direct into the soil in the late fall and they should sprout from the ground in the spring. 

Common Problems

As mentioned above, it is very drought tolerant once established, requires little to no fertilizing, no pruning, and is a very low maintenance green ground cover planting that will fill and add interest to your landscape. There are a few issues worth noting, however. 

Growing Problems

Several factors contribute to the plant’s growing problems.

The most common growing problem occurs when the soil pH requirements are not met. Bearberry will show signs of stress if the pH in the soil is too high. The leaves may turn bronze, it may cease to put on new growth, and may not form flowers at all. It’s important to note that the leaves will turn bronze naturally in late fall moving into winter, however, if the foliage is browning or reddened during the spring and summer, this can be an indicator that the soil pH needs to be raised. 

The acidity of the soil can be raised with a soil acidifier that can be found at your local nursery or big box garden store. Follow the instructions on the back of the package. 

Winter burn can is known to affect evergreens when they experience long periods of drought alongside frozen ground in the winter which prohibits their ability to replace water lost through the process of photosynthesis. As the burns spread, leaves may turn brown and die. 

Avoid planting new bearberries in windy areas to prevent the additional loss of moisture from the soil during the late fall and winter or apply mulch to help retain it. Prune away dead wood if new growth does not reappear and form in your garden in the spring. 

Pests

Aphids are the most common pest and they can be controlled with neem oil.

Aphids are the most common pest because of their succulent foliage and fruit. In a home garden, the best way to battle aphids is to spray them off with a blast of water as soon as you spot them. 

To prevent them from returning and/or overtaking, create an environment that includes a variety of flowering species. This will attract pollinators and other beneficial insects that love to munch on aphids, like ladybugs, for example. In more severe infestations, neem oil or insecticidal soaps can also do the trick. 

Diseases

Root rot is the most common fungal disease that affects the ground cover plants.

Root rot is the most common fungal disease to affect bearberries. They do not like to be in standing water so providing them with well-draining soil will help avoid this issue. Planting them in the right soil helps too. However, if you notice wilting even though it has received plenty of water, mushy stems, and a lack of new growth then this can indicate root rot. 

Letting it dry out completely before watering it again can help starve the fungus.
