Rubber plants like medium to high light and average room temperature. Avoid moving plants from high to low light. Allow the soil to dry womewhat between waterings. Grow in all-purpose mix that's been enriched with compost. Keep them potbound to prevent overwatering; repot only every 3 to 4 years. Feed twice a year, occasionally providing a very dilute vinegar solution. Wipe leave periodically with a damp sponge. Fresh air is very beneficial.
