What condition is less likely to occur in a drier interiorscape environment?

Fungal diseases are typically associated with increased humidity and moisture levels, as these conditions create a favorable environment for the pathogens to thrive. In a drier interiorscape environment, moisture levels in the air and surrounding substrates are reduced, making it less conducive for fungi to develop and spread. This limited moisture decreases the likelihood of conditions necessary for fungal spore germination and growth, thereby reducing the incidence of fungal diseases.

In contrast, insect infestations, weed growth, and root rot can occur under a range of conditions, even in drier environments. For instance, certain pests may be more resilient to low humidity, and weeds can still establish in various situations. Root rot, while often associated with overwatering and poor drainage, can also occur if plants are stressed and weak, allowing opportunistic pathogens to take hold regardless of the overall moisture levels.
