How to care for your Tree Aeonium

Everything you need to keep your Tree Aeonium healthy: watering, light, humidity, feeding, repotting and pruning.

Native to the Canary Islands, *Aeonium arboreum* is a popular succulent cherished for its tree-like growth habit and dramatic rosettes. It develops upright, woody stems that branch to support clusters of fleshy, spoon-shaped leaves arranged in tight rosettes, which can vary in color from bright green to deep burgundy-black, especially in cultivars like 'Zwartkop'. This species actively grows during the cooler, wetter months of fall through spring and enters a period of dormancy during hot, dry summers, often curling its leaves to conserve moisture. Mature plants can produce tall, conical inflorescences of small, star-shaped yellow flowers, after which the flowering rosette dies, though the plant typically continues from offsets.

Watering your Tree Aeonium

Every 10 days

Water thoroughly during its active growing season (fall to spring). Allow the soil to dry out completely between waterings. Keep almost completely dry during summer dormancy.

How to know it needs water

How much light a Tree Aeonium needs

Full sun to partial shade. Needs bright light to maintain compact rosettes and vibrant leaf color, especially for dark-leaved cultivars.

Direct sun tolerated: 4 to 8 h a day
Orientations that suit it: South, South-east, South-west, East, West

Humidity and misting

30–50 %

Low to medium; tolerates average household humidity well. Misting is not recommended and can promote fungal diseases.

Feeding and fertiliser

Every 30 days

Repotting your Tree Aeonium

Every 24 months

When: Fall
Potting mix: Cactus and succulent mix
Mix in: perlite, pumice, coarse sand

The tell-tale signs

Plant is root-bound
Has become top-heavy or leggy
Soil appears depleted or compacted

Pruning your Tree Aeonium

Late fall or early winter, during active growth. Pinch or cut back leggy stems to encourage branching and a fuller shape. Remove spent flower stalks at their base. Cuttings root easily.

Through the year

Watering is not set once and for all: it follows the light and the growth. Allow 25 days between waterings in the depth of winter, against 8 in the growing season.

Good to know

Many Aeoniums, including this species, are winter growers and go dormant in the summer, unlike many other succulents.
The rosettes are monocarpic, meaning the individual rosette will die after flowering, but the plant typically produces offsets from the base or stem.
