Everything it needs
9 essentials at a glance
Watering
Haworth's Aeonium prefers to dry out completely between waterings.
Water every 2-3 weeks during the growing season (spring and summer), using enough water to soak the soil thoroughly. Reduce watering to once a month in fall and winter. Signs of over-watering include yellowing leaves and mushy stems, while under-watering may cause shriveling and leaf drop.
Light
This succulent thrives in full sun to partial shade.
Ideally, it should receive at least 6 hours of direct sunlight daily. If grown indoors, place it near a south or west-facing window. It can tolerate some shade, but too little light may result in leggy growth.
Soil
Aeonium haworthii prefers a well-draining soil mix, ideally a cactus or succulent potting mix with a pH range of 6.0 to 7.0.
Ensure the pot has drainage holes to prevent water retention, which can lead to root rot.
Humidity
This plant prefers low humidity levels, ideally around 30-50%.
To increase humidity, you can mist the plant lightly or place a humidity tray nearby. Signs of humidity stress include browning leaf tips and leaf drop.
Temperature
Haworth's Aeonium thrives in temperatures between 65-80°F (18-27°C) and is hardy in zones 9-11.
It can tolerate brief periods of cold down to 30°F (-1°C) but should be protected from frost and extreme heat.
Fertilizing
Use a balanced, diluted succulent fertilizer with an NPK ratio of 10-10-10 or a specialized cactus fertilizer.
Fertilize every 4-6 weeks during the growing season and avoid fertilizing in winter. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Prune Haworth's Aeonium in early spring to remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. Deadheading spent flowers can also encourage new growth and improve the plant's appearance.
Repotting
Repot every 2-3 years or when the plant outgrows its pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot one size larger with drainage holes, and gently remove the plant from its old pot, loosening the roots if necessary.
Propagation
Propagation can be done through stem cuttings or offsets.
For stem cuttings, take a healthy stem, allow it to callous for 1-2 days, then plant it in well-draining soil. Water lightly until roots develop, usually within a few weeks. The best time to propagate is during the growing season in spring or early summer.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or insufficient light.
How to fix it
Reduce watering frequency and ensure the plant receives adequate sunlight.
Leggy growth
Why it happens
Insufficient light exposure.
How to fix it
Move the plant to a brighter location to encourage compact growth.
Root rot
Why it happens
Poor drainage or over-watering.
How to fix it
Ensure the pot has drainage holes, and allow the soil to dry out completely between waterings. Remove affected roots and repot if necessary.
Browning leaf tips
Why it happens
Low humidity or underwatering.
How to fix it
Increase humidity levels or adjust watering frequency to keep the soil slightly moist.
Leaf drop
Why it happens
Stress from temperature fluctuations or over-watering.
How to fix it
Maintain stable temperatures and adjust watering practices to allow the soil to dry out.
Care through the year
Spring
In spring, resume regular watering and fertilizing as the plant enters its active growth phase. Check for any signs of pests or disease.
Summer
During summer, ensure the plant receives plenty of sunlight and water every 2-3 weeks. Monitor for signs of heat stress, such as wilting.
Fall
In fall, gradually reduce watering frequency as the plant prepares for dormancy. Continue to provide bright light but protect from extreme temperatures.
Winter
In winter, water sparingly, about once a month, and keep the plant in a warm location away from drafts. Avoid fertilizing during this dormant period.
Toxicity & Safety
Haworth's Aeonium is considered non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal upset. Always monitor pets around plants.
