Erysimum albescens prefers consistently moist soil but will not tolerate waterlogging. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering in cooler months to prevent root rot.

Ensure good drainage to avoid fungal issues. Overwatering can be detrimental to this species.

Prune Erysimum albescens after flowering to encourage a bushy habit and promote a second bloom. Remove spent flower stalks and any dead or damaged stems. A light trim can also help maintain its shape.

Avoid heavy pruning, especially into old wood, as it may not regrow.

Propagate Erysimum albescens from semi-hardwood cuttings taken in late summer or early autumn. Dip cuttings in rooting hormone and plant in a well-draining compost. Keep moist and in a warm, sheltered location.

Alternatively, seeds can be sown in autumn or spring.

Repot Erysimum albescens every 2-3 years or when it becomes root-bound. Use a well-draining potting mix, ideally a loam-based compost with added grit or perlite.

Choose a pot that is only slightly larger than the current one to avoid excess moisture retention. Repot in spring.
