About Bearberry Cotoneaster

Cotoneaster dammeri · also called Bearberry Cotoneaster, Dammer's Cotoneaster · flowering

Bearberry Cotoneaster is a vigorous, prostrate evergreen shrub that hugs the ground and roots as it spreads, making it an excellent weed-suppressing groundcover. White flowers in late spring attract pollinators, followed by long-lasting red berries. Extremely cold-hardy and adaptable to a wide range of soils and light conditions.

Growth habit: Prostrate, mat-forming evergreen shrub with stems that root as they spread along the ground

What fertiliser bearberry cotoneaster actually wants — and why

Bearberry Cotoneaster flowers best on poor soil — feed it and you get a lush leafy plant with very few blooms, the exact opposite of what you want.

Little or nothing. Rich, especially nitrogen-rich, soil pushes foliage at the expense of flowers in this plant — lean ground is the technique, not a deficiency.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for bearberry cotoneaster: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed bearberry cotoneaster, and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For bearberry cotoneaster:

Apply a general balanced fertiliser (e.g. 10-10-10) in early spring. Established plants in reasonable soil need little supplemental feeding. Avoid high-nitrogen feeds that promote leafy growth at the expense of flowers and berries. In practice: no routine feeding at all for bearberry cotoneaster — at most a thin compost mulch for soil structure, never a flowering or nitrogen feed.

The dormant-season rule matters more than the exact interval: skip feeding entirely when bearberry cotoneaster is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for bearberry cotoneaster

None is the correct answer for bearberry cotoneaster. The flower-versus-foliage trade-off is the whole point: hold back and you get the display.

Feeding always goes onto already-damp soil, never dry roots — water bearberry cotoneaster first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the bearberry cotoneaster watering schedule.

Signs you are over-feeding bearberry cotoneaster

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for bearberry cotoneaster:

Abundant leafy growth and very few flowers (the classic over-rich symptom).
Soft, floppy stems and a sprawling, leafy habit.
Scorched edges and salt crust if it has been fed in a container.

Signs you are under-feeding bearberry cotoneaster

Effectively never an issue — these plants flower on poverty.
Only on genuinely dead soil: weak, thin growth and few blooms.
A short-lived plant in completely spent container compost.

Flushing and leaching the salts

If bearberry cotoneaster has accidentally been fed and is all leaf, a plain-water flush plus a move to leaner soil resets it; otherwise no flushing is needed because you are not feeding it.

Organic vs synthetic feeds for bearberry cotoneaster

Organic options

A thin compost mulch for soil structure is the absolute most; mostly, give it nothing. UK/US: leave it lean — no manure, no liquid feed. Poor soil is the active ingredient here.

Synthetic / liquid feeds

None. Synthetic feeds, particularly anything with appreciable nitrogen, directly suppress flowering in bearberry cotoneaster.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
