bearberry Care (Arctostaphylos uva-ursi)

This low-growing evergreen groundcover performs best with strong outdoor light and cool conditions.

• Provide 6–8 hours of direct sun daily; full sun promotes dense growth and better flowering for bearberry.
• Tolerates light partial shade, especially with morning sun and dappled or filtered afternoon light, but very deep shade causes thin, patchy foliage.
• In hot summers, protect from intense late-afternoon sun with light shade to reduce leaf scorch and winter desiccation, especially on exposed, windy sites.

This species prefers dry, well-drained soil and is adapted to low-water conditions once established.

• Water newly planted Arctostaphylos uva-ursi when the top 3–5 cm of soil feels dry; in most climates this means deep watering every 5–10 days during the first growing season.
• After establishment, rely on rainfall where possible; irrigate only during extended drought when foliage dulls or curls slightly and soil is dry several cm deep.
• Use sharply drained, sandy or rocky soil; if leaves yellow, stems soften, or soil stays wet for more than 1–2 days after watering, reduce watering and improve drainage.

This cold-hardy shrub is adapted to cool to moderate climates and tolerates significant winter chill.

• Optimal growth occurs around 50–70°F (10–21°C), especially in climates with cool nights and mild summers.
• Plants tolerate winter lows to about -20°F (-29°C) with snow cover; brief drops slightly lower are often survived in established, well-rooted mats.
• Heat tolerance is moderate; in regions with summer highs above 85°F (29°C), provide some afternoon shade and avoid heat-reflective sites such as south-facing walls or asphalt.

Humidity is rarely a concern for Arctostaphylos uva-ursi in typical outdoor conditions.

This plant prefers lean, sharply drained, sandy soil that mimics dry, rocky sites.

• Use a mix of 60–80% coarse sand or grit with low-organic mineral topsoil to keep nutrients modest and structure open.
• Aim for slightly acidic to acidic conditions, roughly pH 4.5–6.0, avoiding limy or strongly alkaline substrates.
• Improve drainage and aeration by incorporating small gravel or crushed granite, especially in heavier native soils.
• Avoid compacted, high-clay, or water-retentive mixes, which quickly cause root decline and increase rot risk for Arctostaphylos uva-ursi.

This species can be grown in containers, but it performs best in wide, low pots that suit its spreading habit.

• Choose a container wider than it is deep so the shallow, spreading roots can colonize the surface layer without staying wet at depth.
• Use a heavy, stable pot or add stones at the base to prevent tipping as the plant spreads over the rim.
• Select a gritty, fast-draining mix and raise the pot on feet so water can exit freely and the drain holes never sit in a saucer of water.

This low-nutrientadapted groundcover usually needs little to no feeding when grown in suitable, lean soil.

Arctostaphylos uva-ursi benefits from light, occasional pruning to maintain a dense, healthy mat.

• Carry out pruning in late spring after flowering, once new growth is visible.
• Remove dead, damaged, or diseased stems first, then thin crowded or overly long runners.
• Use clean, sharp hand pruners and make cuts just above a healthy leaf node.
• Limit pruning to the upper foliage layer to avoid exposing old, woody stems.

This species is rarely kept long term in containers, so care focuses on careful outdoor transplanting.

• Transplant in early spring or early fall when temperatures are mild and soil is moist.
• Choose a shallow, well-drained site with acidic, sandy or gravelly soil, mimicking native conditions.
• Move plants only when necessary, disturbing the root system as little as possible.
• Water thoroughly after planting, then keep soil lightly moist until new growth confirms establishment.

This plant is commonly propagated for groundcover use, but success depends on stable, cool conditions.

• Take semi-ripe stem cuttings in late summer, using non-flowering shoots with a heel of older wood.
• Dip the cut end in rooting hormone and place in a sharply drained, sandy mix under high humidity.
• Layer trailing stems in situ by pinning them into shallow trenches and covering with sandy soil.
• Sow fresh seed outdoors in fall; natural cold stratification over winter improves germination.

This evergreen shrub is very cold hardy and usually needs minimal winter attention in the ground.

• Tolerates freezing temperatures and snow once roots are established in well-drained soil.
• Apply a light mulch of pine needles or bark to buffer soil temperature and retain structure.
• For containers, move pots to a sheltered, unheated area and ensure excess water drains freely.
• Avoid de-icing salts near plantings, as salt buildup can damage roots over winter.
