About China Girl dogwood
Cornus kousa 'China Girl' · also called China Girl dogwood, Kousa dogwood · flowering
China Girl dogwood is a refined deciduous small tree bearing an exceptionally abundant display of large, four-bracted white flowers in June, weeks after North American dogwoods fade. Fleshy, raspberry-like fruits attract birds in autumn, while the foliage turns rich red-purple before falling. It resists dogwood anthracnose, making it more durable than native species.
Growth habit: Upright, vase-shaped small deciduous tree, spreading with age
Watch for — Leaf scorch in alkaline soil: Yellowing between leaf veins (interveinal chlorosis) indicates iron deficiency caused by high soil pH. Acidify with sulfur or ericaceous fertilizer; apply chelated iron as a short-term fix.
What fertiliser china girl dogwood actually wants — and why
China Girl 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 china girl 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 china girl 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 china girl dogwood:
Apply an ericaceous (acidifying) slow-release fertilizer in early spring, before bud break. Avoid high-nitrogen feeds; a balanced or phosphorus-leaning formula supports flowering. Do not fertilize in late summer as it promotes soft growth vulnerable to frost. 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 china girl 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 china girl dogwood
Follow the ericaceous product's own rate — these are formulated for the plant, so the dilution on the label is right for china girl dogwood. The variable that actually matters is pH, not concentration.
Feeding always goes onto already-damp soil, never dry roots — water china girl dogwood first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the china girl dogwood watering schedule.
Signs you are over-feeding china girl dogwood
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for china girl 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 china girl 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 china girl dogwood care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush china girl 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 china girl 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 china girl 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 china girl 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 china girl dogwood?
Flush china girl 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.
