Care at a glance

Light

Forked Aichryson is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. In its native Canary Islands habitat it grows on moist, shaded cliff slopes and in laurel-forest understory. Indoors, bright indirect light or filtered sun is ideal. Avoid blasting midday sun. In low light the plant becomes etiolated and frail — move progressively closer to a window in winter. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water forked aichryson every 10–14 days during active growth; reduced in winter rest. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water moderately during the growing season, allowing the soil to dry to half its depth between waterings. In winter, water less often but do not allow the soil to dry out completely. Reduce significantly (but do not entirely stop) in the rest period and move to a cooler spot.

Soil and pot

Forked Aichryson grows best in sandy loam or cactus compost with good drainage. Grow in slightly acidic (pH 6.1–6.5), sandy or loamy, well-drained soil. Unlike arid-region succulents it tolerates a slightly richer mix. Add 30% perlite or coarse sand to standard cactus compost. Good drainage is still essential — waterlogged roots cause collapse. 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

Forked Aichryson sits happiest at around 45–65% humidity and 2–28°C (36–82°F). Native to moist laurel forests and cliff slopes with coastal Atlantic influence; prefers higher humidity than most succulents. Normal household humidity is usually adequate. Very dry, heated rooms in winter may cause premature leaf loss. If you keep the room above 2–28°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 forked aichryson sparingly. Feed monthly with a balanced liquid fertiliser at half strength during active growth (spring–summer). Move to a cooler, slightly less bright location in winter and cease feeding entirely. 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 forked aichryson in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Etiolation in low lightStems stretch dramatically and weaken in insufficient light, especially in winter. Supplement with a grow light or move to the brightest available position. Biennial plants naturally die after flowering and should be replaced with cuttings.
  • Root rot in waterlogged soilDespite tolerating more moisture than desert succulents, prolonged soggy soil causes rapid collapse. Ensure drainage holes are unobstructed and reduce watering immediately if the stem base feels soft.
  • Aphids on new growthSoft, hairy new shoots attract aphids, particularly in spring. Check the growing tips regularly and treat with insecticidal soap or a forceful water rinse. Avoid systemic insecticides if possible, as the plant is naturally short-lived.

Propagation

Take apical cuttings 8–10 cm long in spring or summer. Callus for 3–5 days, then plant in barely moist sandy mix at 18–22°C. Cuttings root readily within 3–4 weeks. Because the species is biennial, propagating from cuttings annually ensures continuity of the plant in the collection. 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

Forked Aichryson is mildly toxic to pets. Aichryson dichotomum (syn. A. laxum) is noted in some sources as non-toxic, and the genus lacks confirmed bufadienolide compounds. It is not individually listed by ASPCA. Treat with caution and keep out of reach of pets and children; mild digestive upset is possible if ingested in quantity. 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.

Forked Aichryson care — frequently asked questions

What is the common name for Aichryson dichotomum?

Aichryson dichotomum is most commonly called Forked Aichryson, but it is also known as Forked Aichryson, Tree of Love. The names refer to the same species, so care instructions for Forked Aichryson apply identically to anything sold as Tree of Love.

How much light does forked aichryson need?

Forked Aichryson grows best in bright indirect light (just back from a sunny window). In its native Canary Islands habitat it grows on moist, shaded cliff slopes and in laurel-forest understory. Indoors, bright indirect light or filtered sun is ideal. Avoid blasting midday sun. In low light the plant becomes etiolated and frail — move progressively closer to a window in winter.

How often should I water forked aichryson?

Water forked aichryson every 10–14 days during active growth; reduced in winter rest. Water moderately during the growing season, allowing the soil to dry to half its depth between waterings. In winter, water less often but do not allow the soil to dry out completely. Reduce significantly (but do not entirely stop) in the rest period and move to a cooler spot. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is forked aichryson toxic to cats and dogs?

Forked Aichryson is mildly toxic to pets. Aichryson dichotomum (syn. A. laxum) is noted in some sources as non-toxic, and the genus lacks confirmed bufadienolide compounds. It is not individually listed by ASPCA. Treat with caution and keep out of reach of pets and children; mild digestive upset is possible if ingested in quantity.

What USDA hardiness zone does forked aichryson grow in?

Forked Aichryson is rated for USDA zone 9b-11 and RHS hardiness H3. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
