Ox Tongue

One of the few succulents that thrives in lower light. bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well) is ideal, but it tolerates medium to low light (more than 8 feet from a window, or a north-facing room. A grow light 10-12 inches away works great if your windows are not cutting it) that would kill most succulents. Avoid harsh afternoon sun through south- or west-facing windows, which causes sunburn and red discoloration. An east- or north-facing windowsill is perfect.

Prefers dry conditions typical of its arid South African habitat. Tolerates normal indoor humidity levels. Avoid extra misting (note: misting does not actually raise humidity meaningfully. A pebble tray or humidifier is more effective) or placing near humidifiers; lingering moisture encourages fungal problems.

Well-draining cactus and succulent mix, ideally with extra perlite, grit, or coarse sand added. Terra cotta pots are recommended because their porous walls help moisture evaporate. Ensure drainage holes are present.

Root rot from overwatering is the main threat. Black spots indicate fungal infection or bruising. Red leaves signal excessive sun exposure. Watch for mealybugs, scale insects, and fungus gnats. Black spot fungus appears as dark indentations surrounded by yellow halos.
