About Camellia 'Dixie Knight'
Camellia japonica 'Dixie Knight' · also called Dixie Knight camellia · flowering
Camellia japonica 'Dixie Knight' is a vigorous, large-growing cultivar producing spectacular, fully double, deep crimson-red flowers with a peony-like form in mid-spring. Its bold, deep green glossy foliage provides year-round structure. Suited to warm, sheltered gardens or large containers. Mildly toxic if ingested.
Preferred mix: Acidic, humus-rich, well-draining ericaceous soil or compost
Why camellia 'dixie knight' needs this mix
Camellia 'Dixie Knight' is a true acid-lover — it physically cannot take up iron above about pH 5.5, so an ericaceous mix is not optional, it is survival.
- Camellia 'Dixie Knight' has evolved on acidic, peaty ground and depends on soil fungi that only function in acid conditions — raise the pH and it starves even in "rich" soil.
- In a too-alkaline mix iron and manganese lock up chemically, so the youngest leaves yellow between green veins (lime-induced chlorosis) and the plant fades out.
- Its fine, shallow roots also want an open, free-draining structure, not a heavy clay or claggy compost.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons camellia 'dixie knight' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Ordinary multipurpose or garden compost is far too alkaline for camellia 'dixie knight' — expect classic yellowing, weak growth and a slow decline over a season or two.
- Hard tap water slowly pushes the pH up too, undoing a good mix; rainwater is strongly preferred for watering.
- Lime, mushroom compost or wood ash anywhere near this plant is actively harmful.
Planting camellia 'dixie knight' in standard compost or limey garden soil. Without an acidic (ericaceous) medium it will yellow and fail no matter how well you water and feed it.
pH — does it matter for camellia 'dixie knight'?
This is the whole game: Camellia 'Dixie Knight' needs pH 4.5-5.5. Test it, use ericaceous compost (and an ericaceous feed), and water with rainwater where you can to keep the pH from creeping up.
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 ericaceous compost is the correct, easy base for camellia 'dixie knight'; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.
Drainage and the pot
Containers are often easier than open ground because you control the pH completely. Use a pot with good drainage and an ericaceous mix; never let it sit waterlogged.
Top up or refresh the ericaceous mix yearly and test the pH each spring — it naturally drifts upward over time, especially if watered with tap water. When the time comes, our repotting guide for camellia 'dixie knight' covers the timing and technique step by step.
