🌱 How to Care for Cushion Bush to Prevent Scale Insects?

💧 How to Water

Water only when the soil has completely dried out – typically once every 14 days. Once established, a deep watering every two weeks during dry spells is sufficient. Avoid overwatering, as excessive soil moisture causes root rot and can kill the plant.

☀️ Lighting

The plant requires full sun for at least 6 hours a day. In full sun, it grows compactly and maintains its bright silver coloration. In partial shade, it grows more loosely and loses the intensity of its silver color. Avoid deep shade.

🪴 Ideal Soil

It thrives best in poor, alkaline to neutral, well-drained soil (pH 7.0–8.5). Sandy or rocky soil is ideal. Rich, wet, or clay soil is harmful. It does not need fertilization – nutrient-rich soils can cause excessive growth and shorten its lifespan.
