When and how much water
Water Rubber plant when the top 5 cm of soil feel dry to the touch. In summer that’s typically every 6 to 8 days. In winter, slow down to every 11 to 17 days. Use room-temperature water and let any excess drain. Never leave the pot sitting in standing water.
Adjust the timing for the light at the plant, the pot’s size and material, and the humidity indoors. Terracotta dries faster than glazed ceramic.
Light and placement
Rubber plant thrives in bright, indirect light. Direct midday sun can scorch the leaves. Place it 1–2 meters back from an east or west window, or behind a sheer curtain on a south window.
Feeding
Feed Rubber plant every 30 days while it’s actively growing. Use a balanced liquid houseplant fertilizer at half the strength on the label, and only on soil that’s already damp. Feeding dry roots can scorch them.
When growth pauses, skip the fertilizer and let it rest.
Temperature & humidity
Rubber plant is comfortable between 18 and 29 °C. Below 10 °C the leaves start taking damage, so keep it clear of cold drafts and unheated rooms.
It does best at 40–70% humidity. It doesn’t need misting.
Common problems
Yellowing, drooping, and dry edges often point to watering or drainage. Compare the signs before changing the routine.

Common questions
How often should I water a Rubber plant?
Water your Rubber plant (Ficus elastica) when the top 5 cm of soil feel dry to the touch. In summer, that’s typically every 6 to 8 days. In winter, slow down to every 11 to 17 days.
How much light does a Rubber plant need?
Rubber plant thrives in bright, indirect light. Direct midday sun can scorch the leaves. Place it 1–2 meters back from an east or west window, or behind a sheer curtain on a south window.
Is Rubber plant safe for cats and dogs?
The plant contains proteolytic enzyme (ficin) and psoralen. Chewing it can cause oral irritation, drooling, and vomiting. Keep Rubber plant out of reach of pets, or pick a non-toxic alternative like Baby rubber plant, Scarlet star bromeliad, Fuchsia, or Spider plant.
Why are my Rubber plant’s leaves turning yellow or drooping?
On a Rubber plant, yellowing and soft growth usually mean overwatering: watch for yellowing lower leaves, dropping leaves, or mushy stem base. Let the soil dry further between waterings and check drainage. If you see drooping leaves, inward curling leaves, or brown crispy edges instead, it’s likely thirsty. Water a little more often.
