Bearberry

Bearberry, or Arctostaphylos uva-ursi, is a resilient ground cover native to North America. Known for its attractive foliage and red berries, it thrives in rocky, sandy soils and is ideal for low-maintenance gardens.
Everything it needs
9 essentials at a glance
Watering
Bearberry prefers well-drained soil and should be watered sparingly.
Water every 2-3 weeks during the growing season, allowing the top inch of soil to dry out between waterings. In winter, reduce watering to once a month. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and browning leaf edges.
Light
Bearberry thrives in full sun to partial shade.
Ideally, it should receive at least 6 hours of direct sunlight daily. While it can tolerate some shade, too much can lead to leggy growth and reduced flowering.
Soil
This plant prefers sandy or rocky soil with excellent drainage.
A pH range of 5.0 to 6.5 is ideal. A recommended potting mix would be a blend of peat moss, sand, and perlite to ensure aeration and drainage.
Humidity
Bearberry prefers low to moderate humidity levels, around 30-50%.
To increase humidity, you can mist the plant occasionally or place a humidity tray nearby. Signs of humidity stress include leaf curling and browning tips.
Temperature
Bearberry is hardy in USDA zones 3-6.
It thrives in temperatures between 60-75°F (15-24°C) but can tolerate colder temperatures down to -30°F (-34°C). Avoid exposing it to extreme heat above 90°F (32°C) for prolonged periods.
Fertilizing
Use a balanced, slow-release fertilizer with an NPK ratio of 10-10-10.
Fertilize every 4-6 weeks during the growing season. Signs of nutrient deficiency include stunted growth and yellowing leaves, indicating a need for more nutrients.
Pruning
Prune Bearberry in late winter or early spring to maintain shape and remove any dead or damaged branches.
Use sharp, clean pruning shears for best results. Deadheading spent flowers can encourage more blooms.
Repotting
Repot Bearberry every 2-3 years or when it outgrows its pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot that is 1-2 inches larger in diameter, and ensure it has good drainage. Gently remove the plant from its old pot, loosen the roots, and place it in the new pot with fresh soil.
Propagation
Bearberry can be propagated through stem cuttings or seeds.
For stem cuttings, take 4-6 inch cuttings in late spring, dip them in rooting hormone, and plant them in a well-draining potting mix. Keep the soil moist and place in indirect light. For seeds, stratify them for 30 days in a cold environment before planting in spring.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or nutrient deficiency.
How to fix it
Check the soil moisture and reduce watering if necessary. Consider fertilizing if nutrient deficiency is suspected.
Root rot
Why it happens
Root rot is typically caused by poor drainage and over-watering.
How to fix it
Ensure the pot has adequate drainage holes and reduce watering frequency. If root rot is severe, consider repotting into fresh soil.
Wilting leaves
Why it happens
Wilting can occur due to under-watering or extreme heat.
How to fix it
Check soil moisture and water thoroughly if dry. If exposed to high temperatures, provide some shade during the hottest part of the day.
Browning leaf edges
Why it happens
This is often a sign of low humidity or under-watering.
How to fix it
Increase humidity by misting the plant or using a humidity tray, and ensure consistent watering.
Leggy growth
Why it happens
Leggy growth usually results from insufficient light.
How to fix it
Move the plant to a brighter location where it can receive more direct sunlight.
Care through the year
Spring
In spring, prune any dead or damaged branches and fertilize with a balanced slow-release fertilizer. Monitor for new growth and adjust watering as needed.
Summer
During summer, ensure Bearberry receives full sun and water every 2-3 weeks. Watch for signs of heat stress and provide shade if temperatures exceed 90°F.
Fall
In fall, reduce watering as the plant enters dormancy. Remove any fallen leaves or debris around the base to prevent disease.
Winter
In winter, water sparingly, about once a month. Protect the plant from extreme cold by mulching around the base if necessary.
Toxicity & Safety
Bearberry is considered non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal upset. The leaves and berries are generally safe but should not be consumed in excess.
