Guidance regarding the pruning of Nerium oleander emphasizes specific timing to ensure plant health and facilitate propagation.

Initial advice warns against pruning during the main flowering season from June to September to avoid destroying developing buds. Furthermore, heavy pruning after September is discouraged because the plant may not have sufficient time to heal before winter, leaving it vulnerable to frost and fungal infections.

However, September is identified as an ideal month for propagation via cuttings. Because stems remain sap-filled and semi-lignified during this period, gardeners can use healthy, flexible stem tips to create new shrubs. To maintain the plant, it is recommended to perform a sanitary prune that removes no more than one-third of the mass. Due to the high toxicity of the plant, the use of gloves is essential during any pruning process.
