🌱 How to Care for Bietou to Prevent Fungus Gnats?

💧 How to Water

Bietou is drought-tolerant and prefers the soil to dry out between waterings. Water thoroughly approximately every 14 days during summer dry spells. Avoid standing water around the roots—overwatering is the most common mistake. Significantly reduce watering during the winter.

☀️ Lighting

The plant thrives best in full sun (at least 6 hours of direct sunlight daily). It tolerates light shade, but flowering will be less profuse. Avoid heavy shade, as this significantly inhibits growth and flowering.

🪴 Ideal Soil

Use well-drained, sandy soil with moderate nutrient content. A mixture of sand and loam works well. The soil pH should be between 6.0 and 7.5. Heavy clay or waterlogging must be avoided. The plant performs well in nutrient-poor, coastal soils.
