Allow the soil to dry out completely between waterings. Pseudognaphalium canescens is drought-tolerant once established. Overwatering can lead to root rot, so ensure good drainage.

Water thoroughly when dry, typically less frequently in cooler months.

Prune back stems in late spring or early summer to encourage bushier growth and prevent legginess. Deadhead spent flower clusters to maintain appearance and potentially encourage a second bloom.

Light pruning can also be done after flowering to shape the plant.

Pseudognaphalium canescens can be propagated by seeds sown in spring or by stem cuttings taken in late spring or early summer. Seeds can be sown directly into the garden or started indoors.

Cuttings should be rooted in well-draining soil.

Repotting is generally not a frequent necessity as Pseudognaphalium canescens prefers well-drained conditions and can tolerate being slightly root-bound. If repotting is needed, do so in spring into a slightly larger pot with a gritty, well-draining potting mix.
