🌱 How to Care for Slender Deutzia to Prevent Aphids?

💧 How to Water

Water regularly to keep the soil consistently moist, especially during the flowering period and long dry, hot spells. Avoid standing water and overwatering, as this can lead to root rot — the soil surface should dry out slightly between waterings.

☀️ Lighting

It requires full sun for the most abundant flowering but also grows well in partial shade — in intense, direct sun on hot summer afternoons, partial shade helps protect the leaves.

🪴 Ideal Soil

Choose a loose-textured, humus-rich, well-drained soil with a pH between slightly acidic (approx. 5.5) and neutral (approx. 7.5). The shrub thrives in clay, sandy, and loamy soils as long as they do not remain permanently waterlogged.
