Why do Buddhist temples advocate offering flowers instead of offering incense?

They are all forms of worship. This was not said before. In modern times, there may be some places, especially temples that are also tourist attractions. For environmental reasons, it is recommended that everyone worship in the form of offering flowers.

This should be normal. Just like burning paper during the Qingming Festival in the past, but now it is no longer allowed. The reason for advocating sending flowers is similar.
