About Ice Plant
Sedum spectabile · also called Ice Plant, Showy Stonecrop · flowering
Sedum spectabile (now often listed as Hylotelephium spectabile) is a clump-forming border perennial with fleshy, pale blue-green leaves and large flat-topped corymbs of rose-pink star flowers in late summer and autumn. Exceptionally drought-tolerant, it thrives in full sun and lean soil, and its dried seedheads extend winter interest while feeding birds.
Mature size: 30-60 cm tall and 30-45 cm wide (12-24 in)
How to tell ice plant needs repotting
Repotting on a calendar is less reliable than reading the plant. For ice plant, 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.
For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.
How often to repot ice plant
Every 2–3 years, into bone-dry mix. Ice Plant's growth habit — upright, clump-forming herbaceous succulent perennial that dies back to a basal crown in winter and re-sprouts in spring. flat-topped corymbs rise above the foliage in late summer. — sets the pace. Sedum spectabile (now often listed as Hylotelephium spectabile) is a clump-forming border perennial with fleshy, pale blue-green leaves and large flat-topped corymbs of rose-pink star flowers in late summer and autumn. Exceptionally drought-tolerant, it thrives in full sun and lean soil, and its dried seedheads extend winter interest while feeding birds.
What size pot to step ice plant up to
Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Ice Plant 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.
Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.
The best time of year to repot ice plant
Spring or summer, while ice plant 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 ice plant
- Repot dry. Do not water ice plant 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 lean, gritty, sharply drained loam or sandy soil 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 ice plant 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 ice plant 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 ice plant
Ice Plant wants lean, gritty, sharply drained loam or sandy soil. Performs best in poor to average, well-drained, neutral to slightly alkaline soil. Rich, moisture-retentive soil produces lush foliage but weak, floppy stems. Break up heavy clay with 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 ice plant — frequently asked questions
How often should you repot ice plant?
Every 2–3 years, into bone-dry mix for ice plant. Repot ice plant every 2–3 years into a snug pot of lean, gritty, sharply drained loam or sandy soil, 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 ice plant need?
Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Ice Plant 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. Use our pot size calculator to size it from the plant's current pot and root spread.
When is the best time of year to repot ice plant?
Spring or summer, while ice plant 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.
Should you water ice plant after repotting?
No — not straight away. Repot ice plant 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 ice plant after repotting?
Not immediately. Wait about 3 weeks after repotting ice plant. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
