What’s the problem?
The leaves have started drooping on my old rubber plant. After Christmas, I thought it was dehydrated, so I watered it more, but then the bottom leaves turned yellow and dropped off. Then, bizarrely, a new shoot appeared at the base. What’s going on?
Diagnosis
It sounds like root rot, most likely caused by reduced light, seasonal dormancy and/or increased watering. Overwatering in winter can lead to excess moisture in the soil, causing root stress and decay. The yellowing and leaf drop suggest the roots may be struggling to absorb nutrients and oxygen properly, while the new shoot suggests the plant is trying to survive by directing energy to new growth.

Prescription
Remove the plant from its pot and inspect the roots. Healthy roots should be firm and white, while rotting roots will be mushy, dark or smell bad. Trim affected roots with clean scissors then repot the plant into fresh, well-draining soil.
Prevention
Water only when the top 5cm of soil feels dry. And if the pot doesn’t have drainage holes, switch to one that does. Consider supplementing low winter light levels with a grow light.
