🌱 How to Care for Pearly everlasting to Prevent Rust?

💧 How to Water

Water new plants when the top 2-3 cm of soil is dry until they are established. After that, water about once a week in long dry spells; it prefers moderately moist soil but copes with drought. Avoid soggy soil, which leads to stem and root rot.

☀️ Lighting

Full sun gives the most compact plants and the most flowers. It accepts light or partial shade, such as the shade of a building, but becomes floppy and flowers less under trees.

🪴 Ideal Soil

Any well-drained soil: sandy, rocky, chalky or loamy, acid to alkaline. It thrives in poor soil and needs no compost or fertilizer; extra feeding gives weak, lanky growth. Heavy, wet clay is the one thing to avoid.
