Water consistently to keep the soil evenly moist, especially during warmer months and active growth. Allow the top centimeter of soil to dry slightly between waterings.

Reduce watering in cooler periods to prevent waterlogging, as the plant prefers not to sit in soggy conditions.

Pruning is generally not necessary for Theligonum cynocrambe. If the plant becomes leggy or overgrown, light trimming can be done in spring to maintain a more compact shape.

Remove any dead or damaged foliage as needed throughout the growing season.

Propagation is best achieved through fresh seed sown in autumn or early spring. Seeds may require a period of cold stratification.

Alternatively, divisions of established clumps can be made in spring, ensuring each piece has adequate roots and shoots.

Repotting is rarely needed for this plant. If it outgrows its container, repot in spring. Use a well-draining potting mix and choose a pot only slightly larger than the current one.

Handle the roots gently to minimize disturbance.
