Rosemary roots are unusually prone to fungal rot when kept too moist because the plant evolved in Mediterranean soils with excellent drainage; giving rosemary a pot at least one size larger but with very fast-draining mix (60-70% grit or perlite) and allowing the top 2-3 cm to dry between waterings reduces rot risk far more effectively than simply cutting back watering frequency.
