Aeonium ‘Cabernet’ is a visually striking succulent. This hybrid forms compact rosettes, typically growing 1 to 2 feet tall and spreading 3 to 5 feet wide. Its elongated leaves are pale green, transitioning to a rich reddish hue, especially at the tips. The deep red to purple coloration intensifies with ample sunlight.
Caring for Aeonium ‘Cabernet’
Light
Aeonium ‘Cabernet’ thrives in bright, direct sunlight, which develops its dark red coloration. For optimal growth and vibrant hues, aim for at least six hours of direct sunlight daily. In regions with intense summer heat, providing some afternoon shade can prevent leaf scorch. If grown indoors, a south-facing window offers the best light exposure. Consistent pot rotation ensures even growth. Insufficient light can cause leaves to appear lighter, greener, and lead to leggy growth.
Watering
Proper watering is essential for Aeonium ‘Cabernet’, as it is prone to issues from excessive moisture. The “soak and dry” method is recommended: water thoroughly until it drains, then allow the soil to dry completely before watering again. During its active growing season (cooler months), watering every 7 to 10 days is often sufficient. Reduce watering significantly during summer dormancy, perhaps to once a month if temperatures are consistently high. Overwatering can lead to soft, mushy leaves and root rot. Underwatering may cause leaves to shrivel.
Soil
Well-draining soil is necessary for Aeonium ‘Cabernet’ to prevent root rot. A specialized cactus or succulent mix is ideal, providing drainage and aeration. You can also amend regular potting soil by incorporating coarse sand, perlite, or horticultural grit to improve drainage. A slightly richer mix, such as two parts succulent soil to one part regular potting soil, can be beneficial. This blend helps retain more moisture than a pure succulent mix without becoming waterlogged.
Temperature and Dormancy
Aeonium ‘Cabernet’ prefers mild temperatures, ideally 65°F to 75°F (18°C to 24°C) during the day and around 50°F (10°C) at night. It is hardy in USDA Zones 9-11 and can tolerate light frost down to about 30°F (-1°C). Prolonged freezing temperatures necessitate protection. The plant enters dormancy during hot summer months, especially when temperatures exceed 85°F (29°C). During this time, growth slows or stops, and rosettes may close to conserve moisture. Watering should be significantly reduced.
Fertilization
Aeonium ‘Cabernet’ does not require heavy fertilization; a light hand is recommended to avoid overfeeding. Fertilize only during its active growing season, from fall through spring. A balanced, slow-release granular fertilizer applied once in spring, or a liquid fertilizer diluted to half strength, supports healthy growth. Avoid fertilizing during summer dormancy, as nutrient uptake diminishes. Excess nutrients can lead to weak growth or attract pests.
Propagating Aeonium ‘Cabernet’
Propagating Aeonium ‘Cabernet’ is straightforward, with stem cuttings being the most reliable method. Begin by selecting a healthy stem section, ideally 4 to 6 inches long, with fresh top growth that has not yet flowered. Using a clean, sharp knife or shears, make a cut and allow the severed end to dry and form a callus. This callusing process typically takes 3 to 7 days (up to two weeks for thicker stems) and helps prevent rot when planted.
Once callused, plant the cutting into a pot filled with well-draining succulent or cactus soil, burying approximately half of the stem. Position the pot in bright, indirect light. Water sparingly until roots form, which usually occurs within a few weeks. The best time to take cuttings is during the plant’s active growing seasons in fall or spring, ensuring quicker rooting and establishment.
Common Issues and Solutions
Aeonium ‘Cabernet’ can experience leggy growth, characterized by elongated stems and increased spacing between leaves. This often results from insufficient light exposure, as the plant stretches for more sunlight. To correct this, gradually increase the plant’s light exposure, moving it to a brighter location over several days to prevent shock. For severely leggy plants, pruning can encourage bushier growth and a more compact form.
Overwatering is a common cause of rot in Aeonium ‘Cabernet’, leading to mushy leaves and stems that may turn brown or black. To prevent rot, ensure the soil dries completely between waterings and use a pot with adequate drainage holes. If rot is detected, repotting into fresh, well-draining soil and adjusting watering habits can help save the plant.
Pests such as mealybugs and aphids can affect Aeonium ‘Cabernet’. Mealybugs often appear as small, white, cottony masses in leaf axils or on undersides of leaves. Aphids are tiny sap-sucking insects. For minor infestations, physically remove pests using a strong stream of water or by dabbing them with a cotton swab dipped in 70% isopropyl alcohol. For more widespread issues, insecticidal soap or neem oil can be effective. Over-fertilizing can make plants more susceptible to aphid infestations.
