What to do when rubber plant leaves turn yellow? Causes and solutions
1. Replace the soil
Cause: If the rubber plant has not been repotted for a long time, the nutrients in the soil have been almost completely absorbed by the plant, making it difficult to continue supporting normal growth. It will then develop yellow leaves due to insufficient nutrient supply.
Solution: Repot the rubber plant. Carry out the repotting indoors, and prepare a suitable new pot and new soil for it in advance. First adjust the room temperature to around 15°C, then take the plant out of its original pot, cut off the rotten roots, plant it in the new pot and soil, water it thoroughly, and place it in a shaded spot for a period of time; after that, normal care can be resumed.
2. Watering and fertilizing
Cause: Rubber plants have a relatively high demand for water and fertilizer. Not watering or fertilizing for a long time will cause it to lack nutrients and be unable to grow normally, leading to yellow leaves and other symptoms.
Solution: Water and fertilize promptly. If the rubber plant has not been watered for a long time, give it a thorough watering, and afterward water it according to proper methods. If it has not been fertilized for a long time, add some diluted phosphorus-potassium fertilizer.
3. Improve ventilation
Cause: If the rubber plant stays in an overly enclosed environment for a long time without enough fresh air, it may develop yellow leaves as a result.
Solution: Move the rubber plant to a place with good air circulation. If it is grown indoors, open the windows for ventilation at the right times to increase air circulation.
