Did You Know Ficus Elastica Is Toxic? ⚠️ Essential Tips for Keeping It at Home

According to SaedNews Family Service, the Ficus elastica (commonly known as the rubber plant or rubber tree) is a popular houseplant thanks to its large, glossy leaves and striking appearance. Its beautiful foliage enhances the decor of any home.

In its native habitat in Southeast Asia, these plants can grow over 30 meters tall. As an indoor plant, Ficus elastica usually reaches a height of 1 to 3 meters. The plant gets its name from the sap, which is sometimes used to produce rubber. Its leaves are shiny and rubber-like, and when properly cared for, the plant produces impressive foliage. Varieties often have dark green or colored leaves, such as the “Black King” or “Ruby” types, which have deep reddish-black foliage.

Caring for a Ficus elastica is easy, making it a valuable choice if you want a tall houseplant that impresses guests.


Care and Maintenance

The key to Ficus elastica care is balance, meaning the right combination of light and water. If you provide both correctly, you will have a healthy, strong, and tall tree. A drooping plant signals that it needs more water or light.


Light Requirements

Ficus elastica thrives in indirect sunlight. Place it near south- or east-facing windows but avoid direct exposure to hot sunlight, which can burn the leaves. Insufficient light slows growth, and plants in dark areas may lose lower leaves, develop leggy stems, and fade in color.


Watering

  • Summer: Water every 7 days.

  • Winter: Reduce watering to every 10–14 days.

Adjust watering based on the plant’s growth and light conditions. Avoid overwatering or letting the soil dry out completely. Always check drainage holes before watering.


Humidity

Place a container of water near the plant or mist it 1–2 times per week. Avoid misting under direct sunlight to prevent leaf burn.


Temperature

Ideal temperatures range from 15–21°C. The plant can tolerate winter temperatures below 10°C but prefers moderate humidity. Avoid sudden temperature changes, as Ficus elastica is sensitive.


Fertilization

Use plant fertilizer in early spring. Indoor plant fertilizers or liquid organic fertilizers work well. Repeat in late summer but do not over-fertilize, as excessive fertilizer can burn the plant.


Soil

Use high-quality organic potting soil with excellent drainage.


Repotting

Repotting encourages growth. Depending on the current size, repot every 2–4 years. When repotting, gently tap the pot to loosen the soil, transfer the plant to a larger pot, and fill with fresh soil. Avoid excessively large pots to prevent growth issues. If repotting is not possible, replace the top few centimeters of soil with fresh soil.


Propagation

Ficus elastica can be propagated via stem or leaf cuttings or air layering during spring and summer.

Stem Cuttings

  • Take 15 cm cuttings with at least one leaf.

  • Remove extra leaves and soak the cutting in water for 30 minutes to stop sap flow.

  • Plant in a light soil mix (leaf mold, sand, perlite, or cocopeat) and keep the soil moist at 25–27°C.

  • Cover with clear plastic to create a greenhouse effect.

Leaf Cuttings

  • In early spring, cut a young leaf with a sterile knife.

  • Apply rooting hormone and plant in a light soil mix.

  • Maintain high humidity and warmth, using clear plastic for a greenhouse effect.

  • Keep soil moist with a spray bottle until 3–4 new leaves emerge, then transfer to a new pot.

Air Layering

  • In early spring or fall, select a young, strong branch (8–20 mm thick).

  • Make a 2 cm shallow cut between nodes and remove nearby leaves.

  • Optionally apply rooting hormone and wrap with moist moss and plastic.

  • Secure the ends with string and mist daily. Roots form in 1–2 months, after which the branch can be cut and potted.


Pruning and Leaf Cleaning

  • Prune to control height, not width. Avoid pruning in winter.

  • Clean leaves with a damp sponge or cotton cloth; avoid chemical leaf polishes.


Pests and Diseases

  • Common pests: spider mites and scale insects. Use systemic insecticides if needed.

  • Other pests: root-knot nematodes and thrips.

  • Leaf spot fungi can develop in hot, humid conditions.

  • Prevent issues by wiping leaves with a cloth soaked in water and lemon juice.


Common Problems and Remedies

  • Leaf curling or drying: Caused by delayed watering or direct sunlight. Remove damaged leaves and soak the plant base in water for 15 minutes.

  • Yellow leaves: Overwatering or waterlogged soil; allow soil to dry before watering again.

  • Spider mite damage: Leaves with webbing; treat with miticide.

  • Stunted growth: Root issues or small pot; repot in a larger container.

  • White cottony spots: Scale infestation; treat with insecticide.

  • Faded leaves with brown spots: Indicates pest damage; treat with insecticide and repeat in 15 days if needed.


Toxicity

Ficus elastica can cause skin irritation. Wash hands thoroughly after handling. Ingesting parts of the plant may lead to stomach upset, diarrhea, or vomiting, depending on sensitivity.


Important Tips

  • Dry roots are normal and part of the natural growth cycle.

  • Leaf tip burn may indicate water quality or fertilizer issues.

  • Always wear long gloves when handling the plant.

  • Large glossy leaves collect dust easily; clean with a soft, damp cloth.

  • Ficus elastica grows fast but is low-maintenance.

  • Ensure adequate space and light to enjoy this plant as a striking indoor feature.

Key to Success: Maintain balance in watering, fertilization, soil quality, and light exposure. The plant will naturally indicate what it needs over time.
