It is possible that the plant is being cared for less carefully due to its potential to be affected by several factors, including over- or underwatering, poor drainage, and infestation by pests. To assess the condition of the roots, you can cut away the unhealthy portions and prune the roots with sharp garden scissors. It is recommended that the plant be watered every two to three weeks and situated in an area with indirect sunlight. Each part of the plant should be examined for evidence of pests, and if present, an anti-pest spray should be applied.
