About Buffalo Currant
Ribes odoratum · also called buffalo currant, clove currant · edible
Buffalo currant is a tough, deciduous North American shrub prized for clusters of golden, clove-scented spring flowers followed by edible black berries. Extremely cold-hardy and drought-tolerant once established, it suits informal hedges and wildlife gardens. Its spice-perfumed bloom and fiery autumn foliage make it ornamental as well as productive.
Growth habit: Upright to arching, suckering deciduous shrub that spreads slowly into a thicket if unchecked. Fruits on older wood; remove a few oldest stems each winter to renew vigour and keep the centre open.
What fertiliser buffalo currant actually wants — and why
Buffalo Currant feeds in two distinct phases — balanced to build the plant, then high-potassium the moment flowering starts to set and fill a heavy crop.
Balanced (even N-P-K) at planting for roots and frame, then switch to a high-potassium ("high-potash") tomato-style feed once the first flowers open — potassium is what sizes and ripens fruit, not nitrogen.
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 buffalo currant: 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 buffalo currant, 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 buffalo currant:
Undemanding. A spring mulch of compost or a light dressing of balanced fertiliser is usually enough. Avoid heavy nitrogen, which produces lush growth at the expense of flowers and fruit. On poor soils, an annual organic top-dressing maintains steady vigour. So: a balanced feed or compost at planting, then a high-potash liquid every 1-2 weeks from first flower through harvest across the main season (spring through early autumn).
The dormant-season rule matters more than the exact interval: skip feeding entirely when buffalo currant 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 buffalo currant
Follow the crop-feed label rate for buffalo currant — these are calibrated for hungry vegetables. Consistency through fruiting matters more than strength; erratic feeding causes problems like blossom-end rot.
Feeding always goes onto already-damp soil, never dry roots — water buffalo currant first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the buffalo currant watering schedule.
Signs you are over-feeding buffalo currant
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for buffalo currant:
- Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen).
- Lush foliage hiding the crop; soft growth prone to pests and disease.
- Salt crust on the soil and scorched leaf edges in containers.
Signs you are under-feeding buffalo currant
- Pale, yellowing lower leaves and stunted growth.
- Small fruit, poor set, and a quickly exhausted plant.
- Blossom-end rot and weak cropping from erratic or insufficient feeding.
If the symptoms point at watering, light or roots rather than nutrition, the full buffalo currant care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
In containers, fertiliser salts build up fast — water buffalo currant thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.
Organic vs synthetic feeds for buffalo currant
Organic options
Garden compost or well-rotted manure dug in before planting, plus a liquid comfrey or seaweed feed once fruiting starts. UK: comfrey feed or organic Tomorite; US: Espoma Tomato-tone or Neptune's Harvest. Builds soil and feeds in one.
Synthetic / liquid feeds
A balanced feed at planting then a high-potash tomato feed in fruiting — UK: Growmore at planting then Tomorite (Levington) or Phostrogen; US: a balanced 10-10-10 then Miracle-Gro Tomato or a bloom booster.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding buffalo currant look like?
Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen). Lush foliage hiding the crop; soft growth prone to pests and disease. Salt crust on the soil and scorched leaf edges in containers. Staying on a high-nitrogen feed once buffalo currant starts flowering is the classic error — you get a huge leafy plant and a disappointing crop. Switch to high-potash the moment flowers appear.
Should I flush the soil of buffalo currant?
In containers, fertiliser salts build up fast — water buffalo currant thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.
