LIGHT
Rubber tree plants do best in medium to bright indirect light. The solid green and dark burgundy varieties can adapt to less light, but the stems may be weak and the leaves small.
WATER
These plants are a little difficult to water. Allow the top 25-30% of the soil to dry out before watering. Keep the soil drier when your plant is in lower light or the room temperature is cooler. The leaves turn yellow from under-water and perfectly fine leaves may fall off from over-watering.
FERTILIZER
Rubber tree plants do not need much fertilizer. Feed monthly when the plant is actively growing with a balanced plant food diluted to 1/2 the recommended strength.
TEMPERATURE
Indoors they do well in warm temperatures between 70°F-80°F (21.1C°-26.7°C) with a night-time temperature around 65°F (18.3C). Keep a Rubber Tree plant away from cold drafts, air conditioners, heaters, and fireplaces.
