How to care for Tree Aeonium
sunlight
Native to sunny, rocky slopes in the Canary Islands, Tree Aeonium needs the brightest spot you can offer indoors. More light keeps its rosettes compact and its stems sturdy.
Bright indirect light
Place it close to an east, west, or bright south-facing window. This is a good starting point for plants that have been grown in lower light.
Gentle direct sun
A few hours of morning or late-afternoon sun suits it well, especially in cooler months. Introduce stronger sun gradually, as intense hot-afternoon glass can scorch leaves. Dark-leaved cultivars need especially bright light to hold their colour.
watering
Water deeply only after the potting mix has dried well, then let excess drain away. Tree Aeonium grows most in cool, bright weather and usually slows in summer heat.
Autumn - spring
During active growth, water roughly every 1-2 weeks. Check first: the upper half of the mix should feel dry and the pot should be noticeably lighter. Soak the root ball, then empty the saucer.
Summer heat
Growth often pauses in hot weather. Water about every 3-4 weeks only when the mix is dry throughout the pot. Curled or slightly closed rosettes can be a normal heat response, so check the soil before watering.
humidity
Relative humidity
Tree Aeonium comes from the breezy Canary Islands, so it is happy in typical household air and does not need tropical humidity. Around 40-50% is ideal, but it usually manages well at 35% or a little lower when watered appropriately.
Very dry, warm air can make leaf edges crisp and encourage faster loss of older lower leaves. Check the potting mix too, as thirst and summer dormancy can cause similar leaf drop. Avoid misting, which leaves water trapped in the rosettes and can lead to rot.
- Move the plant away from radiators, heating vents, and hot sunny glass.
- Use a small humidifier nearby only if indoor air stays below about 30%.
- Provide good ventilation, especially in cool weather.
temperature
Active growth
Winter minimum
Native to the mild Canary Islands, Tree Aeonium prefers cool, steady conditions rather than hot indoor air. It can handle warmer weather, but bright light and good airflow help prevent stretched, weak growth.
nutrition
October - April
Feed about every 4-6 weeks while it is making new rosettes, using a balanced liquid succulent fertilizer at half strength. Apply to already-moist soil. Stop feeding during the summer rest period and whenever growth has paused.
Nitrogen
A modest supply supports leafy rosettes, but too much can produce soft, stretched growth. A diluted balanced fertilizer provides enough.
Potassium
Potassium supports sturdy stems and overall resilience. It is normally supplied alongside other nutrients in a balanced succulent feed.
soil
Gritty, fast-draining soil
Tree Aeonium has shallow roots that rot in dense, wet compost. Use a cactus mix loosened with pumice, perlite, or coarse grit so water drains quickly while a little organic material supports growth.
pH 6,0 - 7,0
This is slightly acidic to neutral, a range most cactus and succulent mixes naturally provide. Choose a peat- or coir-based mix with mineral grit, rather than trying to adjust pH at home.
