Pruning Salvia macrorrhiza Chiov.
To encourage bushy growth and abundant flowering, prune Salvia macrorrhiza Chiov. regularly. Deadhead spent blooms promptly to encourage the plant to produce new flowers. Additionally, prune back the plant in early spring before new growth begins to remove any dead or damaged branches. Pruning the plant can also help to maintain a more compact form.
Propagation of Salvia Macrorrhiza Chiov.
Salvia macrorrhiza Chiov. can be propagated either through seeds or cuttings.
Propagation by Seeds
The seeds of Salvia macrorrhiza Chiov. can be directly sown into the soil during spring or summer. It is important to maintain a warm and moist environment for the seeds to germinate.
