🌱 How to Care for Black Gem Aloe to Prevent Scale Insects?

💧 How to Water

Use the soak-and-dry method: water thoroughly until it drains from the pot, then wait until the soil is completely dry before watering again, roughly every 2-3 weeks in spring and summer and only monthly or less in fall and winter. Overwatering is the single biggest risk to this plant.

☀️ Lighting

Give it bright light, ideally a south- or west-facing window, or full sun outdoors once acclimated. More light brings out the deeper bronze-red leaf color; low light causes the rosette to stretch and lose color. Introduce strong direct sun gradually to avoid scorching.

🪴 Ideal Soil

Plant in a well-draining cactus/succulent mix amended with 50-70% mineral grit such as coarse sand, pumice, or perlite, and always use a pot with drainage holes.
