Determining whether you are overwatering or underwatering your Calathea requires careful observation and evaluation. Overwatering signs include wet soil, root rot, and yellow leaves that may feel soft or mushy. Underwatering symptoms include dry soil, wilting leaves that feel crispy or brittle, and yellowing leaves that may appear dehydrated. Check the soil moisture level, inspect the roots to determine the cause, and adjust your watering practices accordingly to maintain proper moisture levels without waterlogging or dehydration. Remember that each Calathea plant is unique, and its care requirements may vary. By closely monitoring your plant, providing the right conditions, and making necessary adjustments, you can help your Calathea thrive and maintain vibrant, healthy foliage.
