Main Caring Considerations
Watering
Aeonium arboreum ‘Atropurpureum’ is a low to average water-needing plant, which means it doesn’t require frequent watering. It’s important to allow the soil to dry out between waterings, as overwatering can lead to root rot. During the growing season (spring and summer), water the plant once every 7-10 days or when the top 1-2 inches of soil have dried out. In winter, reduce watering to once every 3-4 weeks, as the plant goes into dormancy.
Light Care
This Aeonium thrives in full sun to partial sun conditions. It needs at least 6 hours of direct sunlight daily to maintain its vibrant dark purple color. If grown indoors, place it near a south or west-facing window for optimal light exposure. However, be cautious of intense afternoon sun in the hottest months, as it can cause sunburn on the leaves. In such cases, providing partial shade during peak sun hours is advised.
Soil Care
Well-draining soil is crucial for the health of Aeonium arboreum ‘Atropurpureum’. It prefers a mix of loam or sand with some organic matter, and it can tolerate acidic, alkaline, or neutral pH levels. A commercially available cactus or succulent mix can also work well. To improve drainage, consider adding perlite or pumice to the mix.
