About Lehmann's Iceplant

Delosperma lehmannii · also called Lehmann's Iceplant, Ice Plant · flowering

Delosperma lehmannii (syn. Corpuscularia lehmannii) is a compact South African succulent with distinctive upright, grey-green leaves arranged in opposing pairs. Bright yellow to orange daisy-like flowers appear in spring and summer. Tender in cold climates, it excels as a container plant or indoor succulent. It is highly drought-tolerant and needs minimal care once established in well-draining soil.

Mature size: Up to 20 cm (8 in) tall; spreading 25–30 cm (10–12 in) wide

Watch for — Root rot from overwatering: Mushy stems at the base signal root rot, typically from overwatering or poor drainage. Allow soil to dry fully between waterings and use a pot with ample drainage holes.

How to tell lehmann's iceplant needs repotting

Repotting on a calendar is less reliable than reading the plant. For lehmann's iceplant, 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 lehmann's iceplant

Every 2–3 years, into bone-dry mix. Lehmann's Iceplant's growth habit — compact, upright to spreading subshrub with densely packed, paired succulent leaves on ascending stems — sets the pace. Delosperma lehmannii (syn. Corpuscularia lehmannii) is a compact South African succulent with distinctive upright, grey-green leaves arranged in opposing pairs. Bright yellow to orange daisy-like flowers appear in spring and summer. Tender in cold climates, it excels as a container plant or indoor succulent. It is highly drought-tolerant and needs minimal care once established in well-draining soil.

What size pot to step lehmann's iceplant up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Lehmann's Iceplant 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 lehmann's iceplant

Spring or summer, while lehmann's iceplant 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 lehmann's iceplant

Repot dry. Do not water lehmann's iceplant 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 sandy, gritty, well-draining cactus or succulent 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 lehmann's iceplant 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 lehmann's iceplant 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 lehmann's iceplant

Lehmann's Iceplant wants sandy, gritty, well-draining cactus or succulent mix. Use a dedicated cactus and succulent compost with 40–50% added coarse sand, perlite, or pumice for rapid drainage. Sensitive to root rot in moisture-retaining soils. Terracotta pots are preferred over plastic for their breathability. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting lehmann's iceplant — frequently asked questions

How often should you repot lehmann's iceplant?

Every 2–3 years, into bone-dry mix for lehmann's iceplant. Repot lehmann's iceplant every 2–3 years into a snug pot of sandy, gritty, well-draining cactus or succulent 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 lehmann's iceplant need?

When is the best time of year to repot lehmann's iceplant?

Should you water lehmann's iceplant after repotting?

No — not straight away. Repot lehmann's iceplant 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 lehmann's iceplant after repotting?

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