When rooting plumeria cuttings, removing the inflorescence (flower stalk) is generally advisable. Here are a few reasons why this is beneficial:

Removing the inflorescence allows the cutting to direct its energy towards establishing roots rather than sustaining flowers. This is crucial for the initial stages of growth when the plant needs all available resources to develop a strong root system.

Focusing the cutting’s energy on root development increases the likelihood of successful rooting. A strong root system is essential for the plant’s overall health and future growth.

Inflorescences and flowers on cuttings can decay if the cutting struggles to provide sufficient nutrients and water to sustain them. This decay can introduce pathogens and lead to disease, harming the cutting.

Supporting flowers adds additional stress to the cutting, which already undergoes stress from being removed from the parent plant and trying to establish itself in a new environment.

Use Clean Tools: Ensure that the shears or scissors you use are clean and sharp to make a clean cut. This helps prevent infection and damage to the cutting.
Cut Close to the Base: Remove the inflorescence as close to its base as possible without damaging the main stem. This helps ensure no unnecessary stubs that could rot are left.
Care After Cutting: After removing the inflorescence, keep the cutting in a well-ventilated, warm, and bright location (but out of direct sunlight) to encourage rooting. Ensure the medium in which the cutting is placed remains moist but not waterlogged.

Following these guidelines can maximize the cutting’s potential for successful rooting and future growth.
