The shock duration after repotting can vary depending on various factors, such as the plant species, size, and overall health. Generally, plants can remain in shock for a few days to a few weeks. During this time, they may exhibit symptoms such as wilting leaves, yellowing, or stunted growth. However, with proper care, most plants, including spider plants, can recover from transplant shock within a few weeks. It's essential to provide optimal conditions, monitor the plant's progress, and be patient during this recovery period.
