Plant care techniques for monitoring hydration and health

Effective plant care relies on recognizing physical signals to determine hydration needs and health issues. Key indicators of water deficiency include loss of leaf turgor, wilting, drooping, and leaves becoming dry or crispy to the touch. Changes in color, such as dull yellowing or brown edges, also signal stress.

Conversely, soft and yellow leaves often indicate overwatering. For specific species like Pittosporum, yellowing leaves that fall can be caused by various factors including excessive moisture, poor drainage, or pests. Diagnosing these issues requires observing whether the yellowing is uniform or localized, checking for root rot through soil odor, and looking for signs of parasites like sticky honeydew or dark spots.
