🌱 How to Care for Burger's Onion to Prevent Sunburn (Sun Scorch)?

💧 How to Water

Water only during the growth period (autumn to early spring), allowing the substrate to dry out completely between waterings—approximately every 2-3 weeks, soaking thoroughly and draining the excess. During summer dormancy, suspend watering almost entirely, offering at most an occasional light misting only if the body begins to visibly shrivel. Never water a Conophytum burgeri still covered by its dry sheath—wait for it to break naturally with new growth.

☀️ Lighting

Prefers strong, direct sunlight for most of the year, such as a window facing the morning sun, but needs protection or light shading on the hottest summer days and right after emerging from dormancy, when the skin is more sensitive and prone to burning.

🪴 Ideal Soil

Use a very fast-draining mineral substrate, such as a cactus/succulent mix enriched with coarse sand, perlite, or pumice (about half the volume), with little organic matter. Pots with generous drainage holes are essential to avoid standing water in the root zone.
