Observe the same leaf twice
Plants commonly sold as calatheas include several related botanical groups. RHS guidance notes that many members of the prayer plant family raise their leaves at night, a movement called nyctinasty. Identify your plant and photograph one healthy leaf in the morning and evening without moving the pot. Those two pictures create a useful reference for its normal behavior. A leaf changing position is an observation; it does not automatically establish a watering problem.
Separate movement from persistent damage
Check whether the leaf returns to its usual position and whether the tissue remains healthy. Curling that persists, new discoloration or a general decline deserves a broader inspection of growing conditions. Compare light, warmth and moisture with guidance for the identified plant. Avoid responding to an evening posture by adding another drink every night. Record the timing alongside any other symptoms so an adviser can distinguish a daily pattern from a developing problem.
Make the plant easy to watch
Choose a suitable place where leaves have room to move without contacting a wall or neighboring pot. Keep the label, because common names can conceal different plants and make later searches confusing. Review photographs over several ordinary days rather than staging the plant in a new position for every image. The exercise is a way to learn the specimen you own. Familiarity with its normal rhythm helps you notice changes that merit attention without turning every graceful movement into an emergency.
