About Satomi Dogwood
Cornus kousa 'Satomi' · also called Satomi Dogwood, Satomi Japanese Dogwood · flowering
Satomi Dogwood is a celebrated Cornus kousa cultivar bearing deep rose-pink to crimson bracts in early summer — one of the most vivid pink-flowered dogwoods. Foliage turns red-purple in autumn alongside ornamental red fruits. Resistant to dogwood anthracnose, it suits woodland gardens and focal plantings in moist, acidic soil.
Growth habit: Upright-vase to broadly pyramidal deciduous tree when mature; layered branching with horizontal tiers
Watch for — Bract colour fading: Bracts fade from rose-pink to white prematurely in intense afternoon heat or alkaline soil. Ensure acidic soil pH and provide some afternoon shade in warmer regions; avoid excess nitrogen fertiliser.
What fertiliser satomi dogwood actually wants — and why
Satomi Dogwood is an acid-loving plant — it can only take up nutrients in acidic soil, so the feed itself matters less than using an ericaceous formula and never liming.
An ericaceous (acidic) fertiliser, formulated to keep the soil pH low and supply iron and trace elements in a form acid-loving roots can absorb. Ordinary feeds and any lime lock out iron and yellow the leaves.
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 satomi 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 satomi 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 satomi dogwood:
Feed with a slow-release balanced or ericaceous fertiliser in spring as growth begins. Avoid excessive nitrogen. Annual mulching with well-rotted leaf mould or compost supports long-term vigour and enhances bract colour. In practice: an ericaceous feed in spring as growth resumes, repeated through the main growing months; never apply lime, bonemeal or wood ash, which raise pH.
The dormant-season rule matters more than the exact interval: skip feeding entirely when satomi 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 satomi dogwood
Follow the ericaceous product's own rate — these are formulated for the plant, so the dilution on the label is right for satomi dogwood. The variable that actually matters is pH, not concentration.
Feeding always goes onto already-damp soil, never dry roots — water satomi dogwood first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the satomi dogwood watering schedule.
Signs you are over-feeding satomi dogwood
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for satomi dogwood:
- Brown, scorched leaf margins from too strong or too frequent a dose.
- White salt crust on the soil surface.
- Soft, lush growth that fruits or flowers poorly.
Signs you are under-feeding satomi dogwood
- Yellowing leaves with green veins (iron chlorosis from high pH).
- Weak growth, poor cropping and an overall pale, stressed look.
- Stunted new shoots in spring despite adequate water and light.
If the symptoms point at watering, light or roots rather than nutrition, the full satomi dogwood care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush satomi dogwood with rainwater (not hard tap water, which raises pH) if salts build up; better still, mulch with pine needles or composted bark and water with rainwater to hold the acidity.
Organic vs synthetic feeds for satomi dogwood
Organic options
Composted pine bark, pine-needle mulch, used coffee grounds and an organic ericaceous feed gently maintain acidity. UK: Vitax or Westland Ericaceous; US: Espoma Holly-tone or Dr. Earth Acid Lovers. Slow, soil-improving, hard to overdo.
Synthetic / liquid feeds
A liquid or granular ericaceous feed — UK: Miracle-Gro Ericaceous, Vitax or Westland; US: Miracle-Gro Acid-Loving Plant Food or Espoma Holly-tone. Pair with rainwater and an acidic mulch for it to work.
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 satomi dogwood look like?
Brown, scorched leaf margins from too strong or too frequent a dose. White salt crust on the soil surface. Soft, lush growth that fruits or flowers poorly. Feeding satomi dogwood an ordinary fertiliser, or growing it in hard tap water / limey soil, is the defining mistake — it triggers lime-induced chlorosis (yellow leaves, green veins) no amount of feeding fixes until the pH comes down.
Should I flush the soil of satomi dogwood?
Flush satomi dogwood with rainwater (not hard tap water, which raises pH) if salts build up; better still, mulch with pine needles or composted bark and water with rainwater to hold the acidity.
