Additional Care Tips

White Meadowsweet prefers consistently moist soil, especially during establishment and dry periods. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, as this can lead to root rot. Once established, it can tolerate short dry spells.

Prune Spiraea alba immediately after flowering to maintain its shape and encourage reblooming. Remove any dead, damaged, or crossing branches at any time. For rejuvenation, cut back older plants harder in late winter or early spring before new growth begins.

Spiraea alba can be propagated from softwood cuttings taken in early summer or semi-hardwood cuttings in mid to late summer. You can also divide established clumps in early spring or late autumn. Seed propagation is possible but may result in offspring that do not come true to type.

Repotting is primarily for container-grown plants or when transplanting. For young plants, repot every 1-2 years in spring. For established plants, repotting is usually only necessary if they become root-bound or need to be divided, typically every 3-5 years, again in early spring.

FAQs

When is the best time to prune White Meadowsweet?

Prune White Meadowsweet in late winter or early spring before new growth begins to encourage flowering on old wood and maintain shape.

What are the light requirements for Spiraea alba?

White Meadowsweet thrives in full sun to partial shade. It will produce more abundant blooms with at least six hours of direct sunlight daily.

How much water does White Meadowsweet need?

Once established, White Meadowsweet is relatively drought-tolerant. Water regularly during dry periods, especially when young, but avoid waterlogged soil.

Is Spiraea alba deer resistant?

White Meadowsweet is generally considered to have some resistance to deer browsing, but this can vary depending on local deer populations and food availability.

What kind of soil is best for White Meadowsweet?
