The rubber tree plant (Ficus elastica) is a spreading evergreen with thick, glossy foliage and a naturally irregular canopy. In its natural environment, this vigorous grower can easily reach heights up to 100 feet. The container-grown rubber tree plant maintains its natural vigor and generally requires repotting every one to two years.
Remove the rubber tree plant gently from its container and place it on a clean, flat surface or table. Gently remove the excessive soil from the root system and carefully inspect the roots. Look for dead or wilted roots. Trim away any damaged roots with sterile pruning shears.
Select a clean, well-drained potting container for your rubber tree plant. Wash the container with hot water and soak if you plan to reuse the same container. Allow it to dry completely.
Repot your rubber tree plant in nutrient-rich, loamy soil. Mix equal parts of nutrient-rich potting soil, coarse, clean sand and moist peat moss, recommends PlantCare.com. Mix the components thoroughly. Dust the mixture lightly with lime and mix the soil thoroughly, again.
Line about one-third of your container with the potting soil. Center the rubber tree plant in the container and fill the container the rest of the way with soil. Make sure all of the roots are covered with soil.
Water your newly repotted rubber tree plant to promote a good establishment and remove any potential air pockets. Irrigate your rubber plant with tepid water and at soil level to prevent wetting the foliage. Water the tree thoroughly and evenly until the water begins to flow from the container’s drainage holes.
Place your rubber tree plant in a warm, sunny location that receives at least six hours of full sunlight. Choose a well-ventilated location that is away from direct temperature variations, such as heating vents, drafty doorways and air conditioners.
