Learn the essentials of rubber plant care, including light needs, watering frequency, and repotting tips for a thriving Ficus elastica indoors.

Quick answer

Place your rubber plant in bright, indirect light, water when the top inch of soil dries out, and repot every 1–2 years using a well-draining potting mix.

Why rubber plants are forgiving but have one non-negotiable

Ficus elastica adapts to lower light better than many indoor trees, but it will drop leaves if moved too often or left in a draft. The one rule you cannot bend is light: too little and the plant becomes leggy; direct hot sun scorches the leaves. A spot a few feet from an east or west window works best.

The watering mistake most new owners make

Rubber plants prefer to dry out between waterings. Overwatering is the fastest way to cause root rot. Stick your finger into the soil; if the top inch feels dry, it's time to water. During winter, reduce frequency because growth slows and the soil stays moist longer.

When and how to repot without stressing the plant

Repot in spring or early summer when the plant is actively growing. Choose a pot only 1–2 inches larger in diameter — too much extra soil holds moisture and can lead to rot. Gently loosen the root ball and use a fresh, well-draining mix. After repotting, wait a week before resuming your normal watering schedule.

Step-by-step rubber plant care routine

Check light conditions: Place your rubber plant in bright, indirect light — a spot near an east- or west-facing window is ideal. Avoid direct midday sun, which can burn the leaves. If leaves turn pale or drop, move the plant closer to the window. If you see brown patches, pull it back from direct sun.
Water only when dry: Insert your finger about one inch into the soil. If it feels dry, water thoroughly until water runs out the drainage hole. If still moist, wait a few more days. Common mistake: watering on a schedule rather than checking soil. Always test moisture first.
Repot every 1–2 years: In spring, move your rubber plant to a pot 1–2 inches wider. Use a well-draining potting mix (standard indoor plant mix works). Water lightly after repotting, then resume normal care after a week. Don't repot into a much larger pot — excess soil stays wet too long and can cause root rot.

Product spotlight

フランスゴム: フランスゴム (Ficus elastica) thrives in bright, indirect light and prefers soil to dry out between waterings. It is moderately cold-hardy, tolerating temperatures down to 3–5°C. This means you can keep your rubber plant happy with a simple routine: water only when the top inch of soil is dry and protect it from temperatures below 5°C in winter.
