About Peacock Pink

Dianthus pavonius · also called Peacock Pink, Cheddar-type Pink · flowering

A distinctive tufted alpine perennial from the south-western Alps, characterised by bearded petals of rich cerise-pink with a purple eye, backed by a buff-brown reverse giving the peacock-eye appearance. Excellent in rock gardens and scree. Requires sharp drainage, full sun, and tolerates alkaline, lean soils well.

Mature size: 10–15 cm tall, 20–30 cm wide

How to tell peacock pink needs repotting

Repotting on a calendar is less reliable than reading the plant. For peacock pink, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot peacock pink

Every 2–3 years, into bone-dry mix. Peacock Pink's growth habit — tufted, mat-forming perennial with narrow grey-green grass-like leaves forming dense mounds — sets the pace. A distinctive tufted alpine perennial from the south-western Alps, characterised by bearded petals of rich cerise-pink with a purple eye, backed by a buff-brown reverse giving the peacock-eye appearance. Excellent in rock gardens and scree. Requires sharp drainage, full sun, and tolerates alkaline, lean soils well.

What size pot to step peacock pink up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Peacock Pink stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot peacock pink

Spring or summer, while peacock pink is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting peacock pink

Repot dry. Do not water peacock pink for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty gritty, alkaline to neutral, sharply drained alpine or scree mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set peacock pink at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep peacock pink completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for peacock pink

Peacock Pink wants gritty, alkaline to neutral, sharply drained alpine or scree mix. pH 6.5–7.5. Mix loam with at least 40–50% coarse grit or limestone chippings. Lean, low-fertility soil is preferred. Rich composts cause lush, disease-prone growth and reduce flowering. Top-dress with fine grit. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting peacock pink — frequently asked questions

How often should you repot peacock pink?

Every 2–3 years, into bone-dry mix for peacock pink. Repot peacock pink every 2–3 years into a snug pot of gritty, alkaline to neutral, sharply drained alpine or scree mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does peacock pink need?

When is the best time of year to repot peacock pink?

Should you water peacock pink after repotting?

No — not straight away. Repot peacock pink into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise peacock pink after repotting?

Not immediately. Wait about 3 weeks after repotting peacock pink. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
