Considering optimal conditions for maintained health in Sansevieria species, I seek clarification on the most reliable physiological indicators to assess overall plant vigor and potential stress. Specifically, what observable parameters—such as leaf turgor, coloration, margin integrity, and growth rate—serve as sensitive markers for proper hydration, substrate health, and adequate illumination? Additionally, are there specific potting mix formulations or nutrient regimes that have been demonstrated to mitigate common pathologies, such as root rot or etiolation, in this typically low-maintenance species? Empirical observations and controlled experimental data would be valuable in quantifying these factors.
