|Why do the leaves fall off? How much sunlight do they like, and what is the recommended temp?|
|Rubber plants like bright light, but never hot sun. When your new leaves are emerging, even less light is advisable, as this will promote larger leaves. Rubber plants are very susceptible to changes in environment, such as warm to a cool room, or drafts from air conditioners or heaters.
Keep your plant evenly moist during the growing cycle in spring and summer, but on the dryer side during the rest of the year. They really appreciate having their leaves sponged off with a damp cloth. When you fertilize your rubber plant in the spring and again in early summer, use a weak mixture of a water soluble house plant food.
Rubber plants have a tendency to lose their lower leaves, usually from environmental stress. If this happens, new shoots will emerge from the old leaf node.
They will be happy in average household temperatures as long as they are out of drafts.
Best wishes with your rubber plant!
