Planting Exochorda

As for most shrubs, it’s best to plant your Exochorda in fall to favor root development before winter and renewed growth in spring.

However, if purchased in a pot or in a container, you can also plant in spring, taking great care to water more during the first few months, especially in summer.

  • Ensure that you have well-drained soil, rich and with lots of humus for a beautiful blooming.
  • Exochorda loves very sunny spots but prefers part shade in regions where summers are hot and dry.
  • Avoid drafty and windy spots to protect the blooming in spring.
  • Proper mulch in summer will help it cope with drought.

Exochorda mostly fears excessively chalky soil so be wary of highly alkaline soils.
