Bethencourt's Aichryson (Bethencourt's Tree Aichryson) care

Light

In the wild bethencourt's aichryson grows on the bright edge of a forest canopy, not in the canopy and not in the open. Indoors, that translates to within a metre of an unobstructed window, sheer curtain optional. Thrives in bright light with several hours of direct morning sun. Protect from harsh midday summer sun which can scorch the hairy leaves. Insufficient light causes leggy, sparse growth and poor flowering. The fastest test: a hand held at the leaf casts a soft-edged shadow at noon — sharp shadow means too much sun, no shadow means too little light.

Watering

Aim for every 10–14 days in the growing season (spring and autumn); sparingly in summer heat and winter rest for bethencourt's aichryson, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Water thoroughly then allow the top half of the soil to dry before watering again. Unlike true desert succulents this species needs consistent moisture during active growth, but root rot sets in quickly if water sits around the roots. Reduce to occasional watering in summer dormancy and winter.

Soil and pot

Bethencourt's Aichryson grows best in 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. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Bethencourt's Aichryson sits happiest at around 30–50% humidity and 10–27°C (50–80°F). Tolerates typical indoor humidity well. Prefers moderate ambient humidity reflecting its Canary Islands coastal-upland origin. Avoid misting the hairy leaves, which can encourage fungal rot. If you keep the room above 10–27°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed bethencourt's aichryson sparingly. Feed monthly during spring and autumn with a balanced liquid fertiliser diluted to half strength. Do not fertilise during summer semi-dormancy or in winter. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on bethencourt's aichryson in the Growli community. Each is annotated with the most common cause so you know where to start.

• 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.
• Etiolation (leggy growth) — Caused by insufficient light. Stems stretch and become thin with widely spaced, pale leaves. Move to a brighter position and prune leggy stems to encourage bushy regrowth.
• Mealybugs — White cottony clusters collect in leaf axils and along stems. Treat with isopropyl alcohol applied with a cotton swab, or use a diluted neem oil spray, repeating weekly until clear.

Propagation

Easily propagated from stem cuttings taken in spring or autumn. Allow cut ends to callous for 2–3 days before inserting into barely moist gritty compost. Seeds can be sown on the surface of fine gritty mix at 18–21°C (65–70°F) in spring. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Bethencourt's Aichryson is mildly toxic to pets. Aichryson is not individually listed by ASPCA. It belongs to Crassulaceae, a family that includes both toxic genera (Crassula/jade, Kalanchoe, Cotyledon) and non-toxic genera (Echeveria, Sedum). No specific toxic principle has been documented for Aichryson, but given the family context and the absence of a confirmed non-toxic listing, caution is advised. Keep away from pets and children until individual confirmation is available. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
