Water Phlomis aucheri thoroughly when the top 2-3 cm of soil are dry. Allow the soil to dry out slightly between waterings, especially during winter dormancy. Avoid overwatering, as this can lead to root rot.

Ensure good drainage to prevent waterlogging.

Prune Phlomis aucheri after flowering to maintain shape and encourage bushier growth. Remove dead or damaged stems at any time. Light pruning in early spring can also help remove winter damage and stimulate new growth.

Propagate Phlomis aucheri from semi-hardwood cuttings taken in summer. Root cuttings in a well-draining, moist medium. Alternatively, sow seeds in autumn or early spring.

Germination can be slow and erratic, so patience is key.

Repot Phlomis aucheri only when it becomes root-bound, typically every 2-3 years. Use a well-draining potting mix. Repot in spring before new growth begins. Water lightly after repotting to help settle the soil.
