🌱 How to Care for Dinteranthus to Prevent Sunburn (Sun Scorch)?

💧 How to Water

Water by soaking the pot and letting it drain, then wait until the mix is completely dry, usually 2-4 weeks in the growing seasons of spring and autumn. Do not water while the new leaf pair is growing out of the old one: wait until the old leaves have fully shriveled. Keep the plant rather dry in the coldest winter month and in dull, cool or very humid weather. Soft, wrinkled-then-mushy heads mean too much water.

☀️ Lighting

Give the most light you can: a south-facing window (north-facing in the southern hemisphere), a bright greenhouse or a grow light. Good light keeps the bodies compact and pale, almost bone-white in D. pole-evansii. Shade lightly from the full midday sun in summer, especially under glass, to avoid scorching, and acclimatise plants gradually when moving them outdoors.

🪴 Ideal Soil

Use a very open, fast-draining mineral mix with little compost and a high proportion of grit, coarse sand, pumice, small lava gravel or pebbles (about 70-80% mineral). Top-dress with gravel so the neck of the plant stays dry. Because the roots are shallow and fibrous, a shallow layer of mix dries faster and is safer than a deep one.
