Growing Styrax

Latin Name Pronunciation:  sty' reks  

The Styrax genus includes about 130 species of flowering shrubs and small trees from woodland clearings in warm, temperate, and subtropical to tropical parts of Southeast Asia, the Mediterranean region, and the Americas. Cultivated varieties are well-suited for use as specimen trees in small yards, grouped informally at woodland edges, or layered beneath tall canopy trees. Plant in humus rich, neutral-to-alkaline, moist soil, with filtered sun or afternoon shade in warmer climates.

Light: Snowbells do well in dappled shade and benefit from more shade, particularly in the afternoon, when grown in warmer zones. In northern climes, they are happy to grow in full sun provided enough moisture.

Soil: Slightly acidic or neutral soil is preferred, pH 6-7. Soil should be moist but well-drained, loose, and rich in organic content. Avoid compacted soils and those that dry out easily. Frequent applications of compost and use of an organic mulch are beneficial.

Watering: Regular deep watering is required to get plants established and during dry spells. Styrax prefers moist soil, so high organic content and mulch will reduce the need for watering.

Fertilizing: A slow-release, balanced, granular fertilizer may be applied in early spring after the first growing season if needed, but often just compost is sufficient.

Pruning: Silverbell trees are naturally graceful and do not require pruning, except for damaged or crossing branches. Flowering occurs on the previous season’s wood, so any necessary pruning should be done just after flowering has finished.

Pests/Diseases: Generally pest-free. Susceptible to leaf scorch in hot, dry conditions and chlorosis in alkaline soil.
