About Vancouver Jade Bearberry
Arctostaphylos uva-ursi 'Vancouver Jade' · also called Vancouver Jade Bearberry, Vancouver Jade Kinnikinnick · edible
Vancouver Jade Bearberry is a selected cultivar of Arctostaphylos uva-ursi prized for its exceptionally vigorous, wide-spreading habit and glossy jade-green foliage. Small pink-white flowers appear in spring, followed by red berries. An outstanding drought-tolerant evergreen ground cover for slopes, banks, and coastal gardens in acidic soils.
Preferred mix: Acidic, sharply drained, sandy or gravelly soil
Watch for — Root rot from poor drainage: This cultivar shares the species' extreme intolerance of wet soils. Plant only on fast-draining, acidic sites and avoid irrigation once established.
Why vancouver jade bearberry needs this mix
Vancouver Jade Bearberry is a true acid-lover — it physically cannot take up iron above about pH 5.5, so an ericaceous mix is not optional, it is survival.
- Vancouver Jade Bearberry has evolved on acidic, peaty ground and depends on soil fungi that only function in acid conditions — raise the pH and it starves even in "rich" soil.
- In a too-alkaline mix iron and manganese lock up chemically, so the youngest leaves yellow between green veins (lime-induced chlorosis) and the plant fades out.
- Its fine, shallow roots also want an open, free-draining structure, not a heavy clay or claggy compost.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons vancouver jade bearberry struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Ordinary multipurpose or garden compost is far too alkaline for vancouver jade bearberry — expect classic yellowing, weak growth and a slow decline over a season or two.
- Hard tap water slowly pushes the pH up too, undoing a good mix; rainwater is strongly preferred for watering.
- Lime, mushroom compost or wood ash anywhere near this plant is actively harmful.
Planting vancouver jade bearberry in standard compost or limey garden soil. Without an acidic (ericaceous) medium it will yellow and fail no matter how well you water and feed it.
pH — does it matter for vancouver jade bearberry?
This is the whole game: Vancouver Jade Bearberry needs pH 4.5-5.5. Test it, use ericaceous compost (and an ericaceous feed), and water with rainwater where you can to keep the pH from creeping up.
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
Bagged ericaceous compost is the correct, easy base for vancouver jade bearberry; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.
Drainage and the pot
Containers are often easier than open ground because you control the pH completely. Use a pot with good drainage and an ericaceous mix; never let it sit waterlogged.
Top up or refresh the ericaceous mix yearly and test the pH each spring — it naturally drifts upward over time, especially if watered with tap water. When the time comes, our repotting guide for vancouver jade bearberry covers the timing and technique step by step.
