To successfully care for a Ficus elastica (Rubber Plant) indoors, provide bright, indirect light, ensure proper watering (allowing the soil to dry out between waterings), maintain moderate humidity, and keep temperatures between 65°F and 85°F. Fertilize monthly with a diluted liquid fertilizer during the growing season.
Light:
Rubber plants thrive in bright, indirect light.
They can tolerate some direct sunlight, but avoid prolonged exposure as it can scorch the leaves.
An east or west-facing window is ideal, providing filtered sunlight.
Watering:
Water every 1-2 weeks, allowing the top inch or two of soil to dry out between waterings.
Increase watering frequency with increased light.
Avoid overwatering, which can lead to root rot and leaf drop.
Humidity:
Normal room humidity is generally sufficient for Ficus elastica.
If you notice your plant's leaves curling or becoming dry, consider increasing humidity by using a humidifier or placing the plant on a pebble tray filled with water.
Temperature:
Maintain temperatures between 65°F and 85°F (18°C and 30°C).
Avoid placing the plant near drafts, hot or cold air vents, or in direct sunlight.
Fertilizing:
Fertilize monthly during the growing season (spring and summer) with a diluted liquid houseplant fertilizer.
Reduce or discontinue fertilizing during the winter months when growth slows.
Other Care Tips:
Potting Mix: Use a well-draining potting mix to prevent root rot.
Repotting: Repot the plant when it becomes root-bound, typically every 1-2 years, using a pot that's slightly larger than the previous one.
Pest Control: Inspect the plant regularly for pests like mealybugs or scale, and treat them promptly with horticultural oil or neem oil.
Pruning: Prune back long stems to encourage bushier growth.
Wipe Leaves: Wipe the leaves with a damp cloth to remove dust and help the plant photosynthesize more efficiently.
Common Problems:
Leaf Drop: Can be caused by overwatering, under-watering, low light, or sudden temperature changes.
Curling Leaves: Can be a sign of underwatering or low humidity.
Yellowing Leaves: Can indicate overwatering, under-watering, or nutrient deficiencies.
Pest Infestation: Mealybugs and scale are common pests. Treat promptly with horticultural oil or neem oil.
