Water Gaura lindheimeri regularly once established, allowing the soil to dry out slightly between waterings. In very hot, dry periods, more frequent watering may be necessary.

Avoid overwatering, as this can lead to root rot. Ensure good drainage to prevent waterlogged conditions.

Prune back established plants in late spring or early summer after the main flush of flowering to encourage a bushier habit and more blooms. Cut stems back by about one-third to one-half.

Deadheading spent flowers throughout the season can also promote continuous blooming.

Gaura lindheimeri can be propagated by stem cuttings taken in late spring or early summer. Use a sharp knife or shears to take 10-15 cm cuttings from healthy, non-flowering stems.

Plant them in a moist, well-draining potting mix and keep them in a warm, bright location until roots form.

Repotting is typically not a frequent requirement for Gaura lindheimeri, as it prefers to be slightly root-bound. If repotting is necessary, do so in early spring before new growth begins.

Choose a pot that is only slightly larger than the current one and ensure it has excellent drainage holes.
