Improper Light
The most likely reason the leaves of your Rubber Tree are fading from deep, dark, burgundy is due to a lack of light. Your plant prefers bright indirect light. It will tolerate low light, but the leaves will fade to a light green color. If your Rubber Tree gets less light while actively growing, the leaves will actually become larger!
If you suspect your plant is fading because of it’s access to light, take a look at your space and find a sunnier spot. Your Rubber Tree would love to be placed near a window.
Time for a check-up
Now is a great time for some TLC. Before you move your plant to its new spot, check in with it to see if it needs a trim or if it could benefit from a good soak.
