If your plant is losing colour, it is usually a sign of stress or inadequate care. One common cause is insufficient light, which can make leaves pale or yellow.
Overwatering can lead to root rot, preventing the plant from absorbing nutrients and leaving the foliage dull. Conversely, underwatering dehydrates the plant and can cause faded or lifeless leaves.
Nutrient deficiencies, particularly a lack of nitrogen, are another frequent reason for colour loss.
Sudden changes in temperature or humidity can also affect leaf vibrancy.
To restore healthy colour, provide the right light, water consistently, fertilise appropriately, and maintain stable growing conditions.
