Water regularly, especially during dry spells, to keep the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings.

Reduce watering in fall and winter as growth slows.

Prune immediately after flowering in late spring or early summer. Remove dead, damaged, or crossing branches. Lightly trim to shape and encourage bushier growth.

Avoid heavy pruning in late summer or fall to prevent stimulating new growth that may be damaged by frost.

Propagate from semi-hardwood cuttings taken in mid-summer. Select healthy stems, dip the cut end in rooting hormone, and insert into a well-draining potting mix.

Keep moist and in a shaded, protected location until roots form.

Repot container-grown Spiraea every 2-3 years in early spring before new growth begins. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix. Water thoroughly after repotting.
