Water consistently, keeping the soil evenly moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings, especially during hot, dry periods.

Reduce watering in fall as the plant enters dormancy, ensuring the soil doesn't become completely dry.

Deadhead spent flowers to encourage reblooming and maintain a tidy appearance. Cut back the foliage to the ground in late fall or early spring before new growth begins.

Remove any diseased or damaged stems as needed throughout the growing season.

Propagate Geranium maculatum by division of established clumps in early spring or fall. Sow fresh seeds outdoors in fall or stratify them indoors for spring sowing.

Stem cuttings can also be taken in late spring or early summer.

Repotting is generally not necessary for Geranium maculatum as it is a perennial that prefers to be established in the ground. If grown in a container and it becomes root-bound, repot into a slightly larger container in early spring before active growth begins.
