About Daphne x burkwoodii 'Carol Mackie'
Daphne x burkwoodii 'Carol Mackie' · also called Carol Mackie daphne, Burkwood daphne Carol Mackie · flowering
'Carol Mackie' is a semi-evergreen Burkwood daphne hybrid with small green leaves neatly edged in creamy gold, giving year-round interest. In late spring it produces masses of fragrant pale-pink flowers, often with a lighter autumn rebloom. More tolerant and reliable than many daphnes, it still demands sharp drainage. All parts are toxic to pets and people.
Preferred mix: Humus-rich, sharply drained, neutral to slightly alkaline loam
Watch for — Sudden dieback: Can collapse abruptly from root rot or stress like other daphnes. Provide sharp drainage, avoid disturbing roots and never transplant established plants.
Why daphne x burkwoodii 'carol mackie' needs this mix
Daphne x burkwoodii 'Carol Mackie' is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Daphne x burkwoodii 'Carol Mackie' 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 daphne x burkwoodii 'carol mackie' 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 daphne x burkwoodii 'carol mackie' — 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 daphne x burkwoodii 'carol mackie' 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 daphne x burkwoodii 'carol mackie'?
Daphne x burkwoodii 'Carol Mackie' 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 daphne x burkwoodii 'carol mackie', but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
