  10. Pruning (As Needed): Prune Aeoniums to remove dead or leggy growth, promoting a more compact and aesthetically pleasing appearance.

How to Care for Aeoniums?

Providing proper care, including balanced watering, adequate sunlight, and occasional pruning, ensures that Aeoniums remain vibrant and healthy. Tailoring their care to mimic their natural habitat allows you to enjoy these captivating succulents to the fullest.

Water

Aeoniums are succulents, and like many succulent species, they prefer a watering routine that emphasizes moderation. Allow the soil to dry out between watering sessions to prevent root rot. In the growing season (spring and fall), water when the top inch of soil is dry. Reduce watering in winter when Aeoniums are in a dormant phase.

Sunlight

Provide them with at least 6 hours of sunlight per day. In hotter climates, some afternoon shade can be beneficial to prevent sunburn. If grown indoors, place Aeoniums near a south or west-facing window to maximize sunlight exposure.

Fertilizer

During the active growing season (spring and summer), feed Aeoniums with a balanced, water-soluble fertilizer. Apply the fertilizer at half strength to avoid nutrient buildup. In the dormant season (fall and winter), reduce or eliminate fertilization.

Soil

Aeoniums thrive in well-draining soil. Use a cactus or succulent mix with added perlite or coarse sand to ensure proper drainage. Repot Aeoniums every 2-3 years or when you notice the soil becoming compacted. Spring is an ideal time for repotting.

Prune

Pruning helps Aeoniums develop a more compact and bushy form. Pinch or trim the tips of the stems to promote branching. Trim leggy or elongated stems to maintain an aesthetically pleasing shape.

Temperature & Humidity

Aeoniums prefer temperatures between 65-75°F (18-24°C) during the day and not below 50°F (10°C) at night. They can tolerate low to moderate humidity levels, making them suitable for various climates.

Container

Opt for containers with drainage holes to prevent waterlogging. The right container size allows for healthy root development. Aeoniums can thrive both indoors and outdoors, but container plants can be moved to shelter during extreme weather conditions.

Type of Aeoniums

Discovering the diversity within the Aeonium genus unveils a range of captivating succulents, each with its distinctive features and charm.

  • Aeonium arboreum: Known for its tree-like growth, Aeonium arboreum features rosettes atop long, bare stems. The leaves are often dark purple or green, creating a visually striking appearance.
  • Aeonium haworthii: A compact species, Aeonium haworthii forms rosettes with spoon-shaped leaves. The leaves display an array of colors, transitioning from green to red or purple at the tips.
  • Aeonium percarneum: This species showcases rosettes with spoon-shaped, glossy green leaves. The edges often have a reddish tint, adding a touch of elegance.
  • Aeonium canariense: Native to the Canary Islands, Aeonium canariense forms large rosettes with wide, spatula-shaped leaves. The plant tends to be more sprawling than upright.
  • Aeonium ‘Sunburst’ (Aeonium decorum): Known for its striking variegation, ‘Sunburst’ features rosettes with green centers and yellow-pink edges. The vibrant colors intensify with increased sunlight.
