Does a dead cordeline smell bad?

Yes, a dead cordyline can emit a bad odor as it decomposes. The smell is often due to the breakdown of organic matter, which can produce unpleasant odors as bacteria and fungi break down the plant material. Additionally, if the plant was affected by disease or pests before dying, this could contribute to a more offensive smell. Regular maintenance and removal of dead plant material can help mitigate these odors.
