Etiolation refers to the abnormal elongation or weakening of plant growth due to lack of sunlight.
In succulents and cacti, etiolation causes the plants to grow leggy, pale, and thin as they stretch towards any available light source. This is an unhealthy condition that indicates the plant is not getting sufficient sunlight to support robust, compact growth. Providing more light exposure can help correct etiolation in succulents and cacti.
