Rubber Plant
Ficus Elastica
Ficus elastica, commonly known as the Rubber Plant, is a popular houseplant appreciated for its glossy leaves and air-purifying qualities. Native to Southeast Asia, it thrives in bright, indirect light and is relatively easy to care for, making it a favorite among plant enthusiasts.
Everything it needs
9 essentials at a glance
Watering
Ficus elastica prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, ensuring the pot has good drainage. In fall and winter, reduce watering to every 2-4 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and dry, crispy edges.
Light
This plant thrives in bright, indirect light but can tolerate low light conditions.
Ideally, place it near a window with filtered sunlight for 6-8 hours a day. Avoid direct sunlight, which can scorch the leaves, but it can adapt to partial shade.
Soil
Ficus elastica prefers a well-draining potting mix, ideally a blend of peat, pine bark, and perlite.
The ideal pH range is between 6.0 and 7.0. Ensure the pot has drainage holes to prevent water accumulation.
Humidity
Ficus elastica enjoys moderate to high humidity levels, ideally around 40-60%.
To increase humidity, consider using a pebble tray with water or a humidifier. Signs of low humidity include leaf browning and curling.
Temperature
The ideal temperature range for Ficus elastica is between 60-75°F (15-24°C).
It is hardy in USDA zones 10-12 and can tolerate brief periods of cooler temperatures but should be protected from frost.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10 or similar during the growing season, every 4-6 weeks.
In fall and winter, reduce fertilization to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Ficus elastica in spring to maintain its shape and encourage bushier growth.
Use clean, sharp pruning shears to remove any dead or damaged leaves. Deadheading is not necessary, but you can trim back leggy growth to promote a fuller appearance.
Repotting
Repot Ficus elastica every 2-3 years or when it outgrows its pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot that is 1-2 inches larger in diameter, and gently loosen the root ball before placing it in fresh potting mix.
Propagation
Ficus elastica can be propagated through stem cuttings.
Take a cutting of about 6 inches with a few leaves attached, dip the cut end in rooting hormone, and plant it in a moist potting mix. Keep the soil consistently moist and place it in bright, indirect light. The best time for propagation is in spring or early summer.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or insufficient light can cause yellowing leaves.
How to fix it
Adjust watering frequency and ensure the plant receives adequate light.
Leaf drop
Why it happens
Sudden changes in temperature or humidity can lead to leaf drop.
How to fix it
Maintain stable environmental conditions and avoid drafts.
Brown leaf edges
Why it happens
Low humidity or under-watering can cause leaf edges to turn brown.
How to fix it
Increase humidity levels and ensure consistent watering.
Root rot
Why it happens
Over-watering and poor drainage can lead to root rot.
How to fix it
Allow the soil to dry out between waterings and ensure proper drainage.
Pests (e.g., spider mites, aphids)
Why it happens
Pests can infest the plant due to low humidity or stress.
How to fix it
Regularly inspect the plant, and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, increase watering as the plant begins to actively grow. Fertilize every 4-6 weeks to promote new growth.
Summer
During summer, ensure the plant receives adequate light and humidity. Water regularly, allowing the top inch of soil to dry out between waterings.
Fall
In fall, gradually reduce watering as growth slows. Continue fertilizing until late fall, then switch to a less frequent schedule.
Winter
In winter, reduce watering to every 2-4 weeks and keep the plant in a warm area away from drafts. Avoid fertilizing during this dormant period.
Toxicity & Safety
Ficus elastica is toxic to pets, particularly cats and dogs, as well as children. The sap can cause skin irritation, and ingestion may lead to symptoms such as vomiting and diarrhea.
