About Cornelian Cherry Dogwood
Cornus mas · also called cornelian cherry, cornelian cherry dogwood · edible
Cornelian cherry is a tough, early-flowering dogwood grown for both ornament and fruit. Clusters of bright yellow flowers open on bare stems in late winter, well before leaves, then ripen to glossy red, tart-sweet edible cherries used for preserves, syrups, and liqueurs. It is adaptable, drought-tolerant once established, and far more forgiving than most dogwoods.
Growth habit: Large multi-stemmed deciduous shrub or small tree with a dense, rounded, twiggy habit. Can be grown as a specimen, an informal hedge, or trained to a single trunk.
What fertiliser cornelian cherry dogwood actually wants — and why
Cornelian Cherry Dogwood 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 cornelian cherry dogwood: 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 cornelian cherry dogwood, 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 cornelian cherry dogwood:
Low feeding needs. A spring top-dressing of compost or a light balanced fertilizer supports growth and fruiting. Excess nitrogen favors foliage over flowers and fruit, so feed sparingly once established. 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 cornelian cherry dogwood 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 cornelian cherry dogwood
Follow the crop-feed label rate for cornelian cherry dogwood — 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 cornelian cherry dogwood first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the cornelian cherry dogwood watering schedule.
Signs you are over-feeding cornelian cherry dogwood
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for cornelian cherry dogwood:
- 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 cornelian cherry dogwood
- 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 cornelian cherry dogwood 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 cornelian cherry dogwood 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 cornelian cherry dogwood
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 cornelian cherry dogwood 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 cornelian cherry dogwood 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 cornelian cherry dogwood?
In containers, fertiliser salts build up fast — water cornelian cherry dogwood 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.
