About Stonecrop-leaf Aichryson

Aichryson sedifolium · also called Stonecrop-leaf Aichryson, Miniature Canary Island Succulent · houseplant

A compact, densely branched succulent subshrub endemic to Tenerife and La Gomera in the Canary Islands, bearing small rosettes of glossy, pale green to yellowish leaves with distinctive reddish lines near the tips. It grows actively in cool months and semi-rests in summer. Undemanding on a bright windowsill and an appealing choice for miniature succulent gardens.

Mature size: Up to 30–40 cm (12–16 in) tall; individual rosettes 2–3 cm (0.8–1.2 in) across

Watch for — Stem rot from overwatering: The shallow root system rots quickly in waterlogged conditions. Ensure the pot drains freely, use a gritty mix, and always let the soil partially dry before watering again.

How to tell stonecrop-leaf aichryson needs repotting

Repotting on a calendar is less reliable than reading the plant. For stonecrop-leaf aichryson, 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 stonecrop-leaf aichryson

Every 2–3 years, into bone-dry mix. Stonecrop-leaf Aichryson's growth habit — compact, densely branched evergreen succulent subshrub; each branch terminates in a small rosette of fleshy, obovate leaves with reddish patterning near tips; produces sprays of small yellow star-shaped flowers in spring and early summer. — sets the pace.

What size pot to step stonecrop-leaf aichryson up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Stonecrop-leaf Aichryson 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 stonecrop-leaf aichryson

Spring or summer, while stonecrop-leaf aichryson 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 stonecrop-leaf aichryson

Repot dry. Do not water stonecrop-leaf aichryson 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 well-drained cactus and succulent mix, ideally in a shallow pot 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 stonecrop-leaf aichryson 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 stonecrop-leaf aichryson 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 stonecrop-leaf aichryson

Stonecrop-leaf Aichryson wants well-drained cactus and succulent mix, ideally in a shallow pot. A blend of 40% coarse sand or perlite and 60% cactus compost works well. The root system is shallow, so use low, wide containers with ample drainage holes. Avoid moisture-retaining peat-heavy mixes. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting stonecrop-leaf aichryson — frequently asked questions

How often should you repot stonecrop-leaf aichryson?

Every 2–3 years, into bone-dry mix for stonecrop-leaf aichryson. Repot stonecrop-leaf aichryson every 2–3 years into a snug pot of well-drained cactus and succulent mix, ideally in a shallow pot, 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 stonecrop-leaf aichryson need?

When is the best time of year to repot stonecrop-leaf aichryson?

Should you water stonecrop-leaf aichryson after repotting?

No — not straight away. Repot stonecrop-leaf aichryson 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 stonecrop-leaf aichryson after repotting?
