Care Guide
The Rubber Tree is a relatively easy plant to care for, but it does require some attention to thrive. Here are some tips for caring for your Rubber Tree:
- Water: Water your Rubber Tree when the top inch of soil feels dry to the touch. Be sure to use room-temperature water and avoid overwatering, which can lead to root rot.
- Fertilization: Fertilize your Rubber Tree every two weeks during the growing season (spring and summer) with a balanced fertilizer. Reduce fertilization during the winter months.
- Soil: The Rubber Tree prefers well-draining soil that is rich in organic matter. A mix of peat moss, perlite, and vermiculite is a good choice.
- Sunlight: The Rubber Tree prefers bright, indirect sunlight but can tolerate some direct sunlight. Avoid placing it in full sun, as this can scorch the leaves.
- Hardiness Zones: The Rubber Tree is hardy in USDA zones 10-12.
Common Pests & Diseases
The Rubber Tree is susceptible to a few common pests and diseases, including:
- Mealybugs: These small, white insects can be found on the undersides of leaves and along the stems. They suck sap from the plant and can cause yellowing and stunting.
- Spider mites: These tiny pests can be identified by the fine webbing they leave on the plant. They suck sap from the leaves and can cause discoloration and leaf drop.
- Root rot: Overwatering can lead to root rot, which is characterized by brown, mushy roots. To prevent root rot, be sure to allow the soil to dry out between waterings.
Habitat
The Rubber Tree is native to the Amazon Basin in South America, where it grows in tropical rainforests. It is now widely cultivated in tropical regions around the world, including Southeast Asia and West Africa. The tree prefers a warm, humid climate with plenty of rainfall and well-draining soil.
