Soil Type

Water: Climbing onion, native to arid Africa, exhibits drought tolerance and water storage in its bulbous shape. Water climbing onion every 2-3 weeks, ensuring soil completely dries out between sessions. Thrives in well-draining soil, reflecting its natural low-humidity habitat.

Fertilize: Nourish climbing onion with a balanced succulent fertilizer monthly at half-strength during spring and summer. Use well-draining potting mix, and avoid over-fertilization. Water climbing onion before fertilizing. Adjust feeding based on climbing onion's health, growth rate, and seasonal changes, and stop feeding during dormancy.

Propagation: To propagate climbing onion, use its tubers in spring. Although beginners may find it challenging, success is indicated by sprouting leaves. Key factors for successful propagation include careful monitoring of watering and ensuring proper drainage.

Repotting: Repot climbing onion every 2-3 years in early spring, using a snug, well-draining container slightly larger than its bulbous base. Post-repotting, provide bright indirect light and minimal watering until new growth appears, supporting strong recovery and climbing growth.
