About Point Reyes bearberry
Arctostaphylos uva-ursi 'Point Reyes' · also called Point Reyes bearberry, Point Reyes kinnikinnick · flowering
A prostrate California-origin cultivar of bearberry, selected from Point Reyes National Seashore for superior heat and drought tolerance. Produces small urn-shaped white-pink flowers in early spring followed by glossy red berries beloved by wildlife. Superb drought-tolerant groundcover for slopes, rock gardens, and lawn substitutes once established.
Preferred mix: Well-drained, acidic, sandy or rocky; tolerates poor, infertile soils
Watch for — Root rot from poor drainage or overwatering: The most common cause of decline. Established plants should receive little to no summer irrigation. Plant in sharply drained, lean soils and avoid watering once establishment is complete (after 2 seasons).
Why point reyes bearberry needs this mix
Point Reyes bearberry flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for point reyes bearberry: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons point reyes bearberry struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives point reyes bearberry weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving point reyes bearberry in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for point reyes bearberry?
Most flowering plants, including point reyes bearberry, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A quality bagged compost works for point reyes bearberry in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for point reyes bearberry covers the timing and technique step by step.
