Mullein foxgloves, a genus of flowering plants, requires specific care to thrive. Basic needs include access to full or partial sunlight, moist and well-drained soil, and temperate climate conditions. Overwatering or poor water management can lead to root rot, a common challenge for this genus, as well as possible insect infestation or diseases. Seasonal considerations vary, with a need for more water during the hot summer months and reduced watering during winter while ensuring the plant is not exposed to frost.
