Adding Spiraea alba to your garden is a breeze. It thrives in full sun locations but can also tolerate some light shade.

Here are some key things to remember for happy Spiraea alba:

  • Watering: During the first growing season, consistent watering is crucial for establishing a strong root system. After that, established plants are fairly drought tolerant, but providing supplemental water during periods of extended dryness will encourage blooming.
