Water regularly during the growing season, ensuring the soil dries out slightly between waterings. Overwatering can lead to root rot. Reduce watering in fall and winter, especially if grown outdoors.

Aim for consistently moist but not waterlogged soil.

Deadhead spent flowers regularly to encourage continuous blooming.

Cut back the plant by about one-third after the main flowering period in late summer or early fall to maintain a tidy shape and promote stronger growth next season. Remove any dead or damaged stems.

Propagate by seed sown in early spring, either directly outdoors or started indoors a few weeks prior. Cuttings can also be taken from non-flowering shoots in late spring or early summer.

Ensure cuttings are kept in a humid environment until rooted.

Gypsophila paniculata generally prefers to be slightly root-bound and does not require frequent repotting. If repotting is necessary for container-grown plants, do so in early spring before new growth begins.

Use a well-draining potting mix and a slightly larger pot.
