Stem rots predominantly affect herbaceous ornamentals due to their softer, more succulent tissues, which are more susceptible to fungal infections and decay. These types of plants typically have less tough, woody structures compared to woody shrubs, where the bark provides some level of protection against pathogens. The moist conditions that often accompany cultivation practices for herbaceous ornamentals can create an ideal environment for the pathogens that cause stem rots to thrive.

In contrast, woody shrubs and tropical plants generally have more developed defense mechanisms, such as thicker bark and woody stems, making them less vulnerable to the diseases that result in stem rots. Succulents, on the other hand, are adapted to store water in their leaves or stems, and while they can suffer from root rot due to poor drainage, they tend to be less affected by stem rots compared to herbaceous ornamentals. Such plant characteristics play a crucial role in the susceptibility to various types of rots, aligning with the observation that stem rots are more frequently observed in herbaceous species.
