White Meadowsweet prefers consistently moist soil but can tolerate brief dry periods once established. Water deeply when the top inch of soil feels dry, especially during hot, dry weather.

Avoid waterlogged conditions, which can lead to root rot. Proper drainage is essential for healthy growth.

Prune Spiraea alba after flowering to maintain its shape and size, or in late winter/early spring before new growth begins to remove any dead or damaged branches.

Pruning encourages denser growth and more flowers in the following season. Light trimming can be done anytime to manage its form.

White Meadowsweet is easily propagated by softwood cuttings taken in late spring or early summer. Dip cuttings in rooting hormone and plant in a moist, well-draining medium.

Alternatively, division of established clumps in early spring is an effective method for increasing plant numbers.

Repotting is typically only necessary for young plants or if the shrub is being moved. For container-grown specimens, repot into a slightly larger container when root-bound, usually every 2-3 years.

Use a well-draining potting mix. Early spring is the ideal time for repotting.
