About Bethencourt's Aichryson

Aichryson bethencourtianum · also called Bethencourt's Aichryson, Bethencourt's Tree Aichryson · houseplant

A compact, densely branched succulent shrublet endemic to the Canary Islands, forming woody-stemmed mounds of hairy, obovate leaves often tinged purplish-red. It produces clusters of golden-yellow star-shaped flowers in spring and summer. Grow in bright light with excellent drainage, and water sparingly in summer; it needs more moisture than desert succulents but none in cold rest.

Mature size: 15–20 cm (6–8 in) tall and 20–30 cm (8–12 in) wide

Watch for — Root rot: The most common issue, caused by overwatering or poorly draining soil. Leaves turn mushy and stems collapse at the base. Remove affected roots, allow to dry, and repot into fresh gritty mix.

How to tell bethencourt's aichryson needs repotting

Repotting on a calendar is less reliable than reading the plant. For bethencourt's 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 bethencourt's aichryson

Every 2–3 years, into bone-dry mix. Bethencourt's Aichryson's growth habit — compact, densely branched succulent shrublet with woody stems; forms a low spreading mound — sets the pace.

What size pot to step bethencourt's aichryson up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Bethencourt's 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 bethencourt's aichryson

Spring or summer, while bethencourt's 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 bethencourt's aichryson

Repot dry. Do not water bethencourt's 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 gritty, well-draining loam 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 bethencourt's 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 bethencourt's 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 bethencourt's aichryson

Bethencourt's Aichryson wants gritty, well-draining loam. Use a standard potting mix amended with 30–40% perlite or coarse grit. Avoid dedicated cactus mixes, which dry out too fast for this species. Good drainage is non-negotiable — never allow water to pool at the base of the pot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
