Aeonium 'Medusa'

Bright indirect light to partial sun — a bright south or east-facing windowsill is ideal indoors. Some direct morning sun is fine and intensifies the crimson-red colouration; harsh afternoon sun in Indian summers can scorch and bleach the rosettes. Outdoors during the cool growing season (October–March), an open bright position with morning sun and afternoon shade works well. In lower light, the rosettes lose their compact form, etiolate outward, and the deep red and near-black colours fade significantly. A grow light at 12 hours is excellent for maintaining colour through India's dimmer winter months.

More water than most succulents — but overwatering is still the primary killer. During the active growing season (October–April), water thoroughly and allow the soil to dry out before watering again; every 7–14 days is typical in cool weather. Bottom-watering is preferred — place the pot in a shallow tray for 20–30 minutes to allow the roots to draw moisture without wetting the ciliate leaf surfaces. In summer dormancy, reduce to barely any water — just enough to prevent complete desiccation of the corms every 3–4 weeks if the weather is very dry. Never water into the centre of the rosette; water collects there and causes rot.

Average to low humidity (30–50%) — this is a Canary Islands succulent and prefers dry air. Do not mist; water sitting on the ciliate leaf surfaces or collecting in the rosette centre encourages fungal rot. India's dry winter season is naturally well-suited to the active growing period. In very humid coastal conditions, ensure excellent air circulation around the plant to prevent fungal issues. No humidifier needed at any time.

Well-draining gritty mix — cactus and succulent soil amended with 50% coarse mineral grit (coarse sand, pumice, or perlite). Unlike ultra-dry cacti, the Aeonium benefits from a slightly more organic component than a pure grit mix, but drainage must still be immediate and complete. pH 6.0–7.0. A terracotta pot with drainage holes is ideal — the porous walls assist evaporation and prevent moisture build-up. A decorative mineral top-dressing keeps the rosette base dry and reduces fungus gnats. Repot every 2–3 years in spring at the start of the growing season.

Light feeder — balanced liquid fertilizer at half strength once a month during the active growing season (October–April). Apply to moist soil only; never fertilize a dry plant or a dormant plant. Two to three feeds per season is sufficient; over-fertilizing produces soft, weak growth that loses the compact rosette form and dilutes the intense colouration. Stop feeding entirely from May through September. Slow-release granules mixed lightly into the top layer of soil at repotting are a good low-maintenance alternative.
