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.
Preferred mix: Moist, humus-rich, well-draining acidic to neutral loam
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.
Why china girl dogwood needs this mix
China Girl dogwood is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- China Girl dogwood evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
- A lean, low-nutrient mix keeps growth firm and aromatic; a rich one gives soft, sappy, flavourless growth that flops and rots.
- It tolerates and often prefers a slightly alkaline soil, the opposite of most houseplants.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons china girl dogwood struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Rich, moisture-holding compost is the classic killer of china girl dogwood — especially over a cold, wet winter, when the base of the plant simply rots.
- A peaty, acidic potting mix is doubly wrong: too wet and the wrong pH direction.
- No grit means the rootball stays damp for days, which a dry-climate root system never copes with.
Growing china girl dogwood in ordinary rich, moisture-retentive compost. Lean it out with at least a third grit, and never let it sit wet over winter.
pH — does it matter for china girl dogwood?
China Girl dogwood likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged "herb" or "Mediterranean" mixes are usually fine for china girl dogwood, but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
Drainage and the pot
Sharp drainage is everything: a terracotta pot with a big hole, gritty mix and never a saucer left full. Raised beds suit these herbs outdoors for the same reason.
A gritty mix barely breaks down, so china girl dogwood needs little repotting — refresh the top layer and the grit every couple of years rather than potting on aggressively. When the time comes, our repotting guide for china girl dogwood covers the timing and technique step by step.
