Water consistently when the top 2-3 cm of soil feels dry, especially during hot, dry periods. Avoid waterlogging, as Spiraea prunifolia prefers well-drained soil.

Reduce watering in fall as growth slows, but do not let the soil become completely parched.

Prune immediately after flowering to maintain shape and remove spent blooms. This encourages rebloom and prevents seed formation.

For overgrown shrubs, a more severe pruning can be done in late winter or early spring to revitalize the plant. Remove any dead or damaged branches anytime.

Easily propagated from softwood cuttings taken in late spring or early summer. Dip cuttings in rooting hormone and plant in a moist, well-draining medium.

Alternatively, layering can be successful by bending a low-growing stem to the ground and covering a section with soil, pinning it in place until roots form.

Young plants may benefit from repotting every 1-2 years into a slightly larger container in spring before new growth starts.

For established shrubs in the ground, repotting is generally not necessary unless transplanting is required. Ensure adequate drainage in any container used.
