Domakihub How to Grow a Rubber Plant: Care Tips for Thriving Ficus Elastica
Everything you need to know to grow a bold, glossy rubber plant indoors.
Reviewed by Domakihub garden pros · 2026-06-23 · 5 min read
The rubber plant (Ficus elastica) is one of the most rewarding indoor plants you can own — its large, waxy leaves add instant character to a living room, a holiday rental villa, or a hotel lobby. The video above walks through the visual basics; this guide turns those essentials into clear, ordered steps tailored to Greek homes, where bright Mediterranean light and dry summers create a distinct growing environment. Follow these steps and your rubber plant will reward you with lush, upright growth year after year.
Why Rubber Plants Work So Well in Greek Interiors
Ficus elastica originates from the tropical forests of South and Southeast Asia, so it actually enjoys warm temperatures — which makes it ideally suited to Greek homes that stay warm well into autumn. Unlike many houseplants that sulk in summer heat, a rubber plant handles indoor temperatures of 18–30 °C without complaint, a range that covers most Greek apartments and rental properties throughout the year.
The plant's size is also an asset. A mature rubber plant can reach two metres or more indoors, creating a living focal point that is far more impressive — and more durable — than cut flowers. For holiday rentals and boutique hotels in particular, a well-grown specimen signals quality and care to guests without requiring daily maintenance.
Choosing the Right Spot and Pot
Light is the single biggest factor in rubber plant success. The plant thrives in bright, indirect light — think a spot one to two metres from a south- or east-facing window, where it receives plenty of luminosity without midday sun scorching the leaves. In Greece, direct afternoon sun through unfiltered glass will bleach and burn the foliage, so use a sheer curtain or recess the plant slightly from the window during peak summer months.
Pot choice matters too. Rubber plants prefer to be slightly root-bound, so resist the urge to pot up too quickly. Choose a container with good drainage holes — terracotta works well in Greece because it allows excess moisture to evaporate, reducing the risk of root rot in humid coastal areas. Repot only when you see roots emerging from the drainage holes, typically every two years.
5 Steps to Grow a Healthy Rubber Plant
- 1
Pick the right light position
Place your rubber plant in bright, indirect light away from harsh midday sun. A north-facing wall is too dark; a south-facing window with a sheer curtain is ideal. Rotate the pot a quarter turn every two weeks so all sides receive even light and the plant grows upright rather than leaning.
- 2
Water deeply but infrequently
Check the soil by pressing your finger two centimetres into the compost. Water only when that top layer is dry to the touch — in a Greek summer this may mean every five to seven days; in a cool, overcast winter, once every ten to fourteen days is enough. When you do water, pour slowly until water drains freely from the bottom, then empty the saucer so the roots never sit in standing water.

Feed during the growing season
From April through September, apply a balanced liquid fertiliser (20-20-20 NPK) diluted to half-strength every two to three weeks. Skip feeding entirely from October to March when the plant's growth slows. Over-fertilising in winter causes weak, leggy growth and can burn the roots, so restraint is key during the cooler months.
- 4
Clean the leaves and maintain humidity
The large, glossy leaves collect dust, which blocks light and reduces photosynthesis. Wipe each leaf gently with a damp cloth every month. In very dry Greek summers or air-conditioned interiors, mist the foliage lightly in the morning, or place a shallow tray of pebbles and water beneath the pot — but do not let the pot base touch the water directly.
- 5
Prune to control size and encourage branching
Use clean, sharp scissors or pruning shears to cut stems just above a leaf node. Pruning in early spring encourages the plant to branch out sideways rather than growing in a single tall column. Wear gloves when pruning — the white milky sap (latex) is a skin irritant. After cutting, press a clean cloth to the wound for thirty seconds to slow the sap flow.

FAQ
- How often should I water a rubber plant in a hot Greek summer?
- In summer heat, check the top two centimetres of soil every four to five days. Water thoroughly when that layer feels dry, which typically works out to once a week. In air-conditioned rooms the soil dries more slowly, so always test before watering rather than following a fixed schedule.
- My rubber plant is dropping leaves — what is wrong?
- Sudden leaf drop is almost always caused by one of three things: a drastic change in light (moving the plant to a darker spot), cold draughts from air conditioning or an open window, or overwatering. Check the soil for sogginess, move the plant back to its original bright spot, and keep it away from direct airflow. It should stabilise within two to three weeks.
- Can a rubber plant grow outdoors in Greece?
- Yes, in sheltered positions in mainland and island Greece with mild winters, rubber plants can grow outdoors in a large container on a terrace or courtyard. They need protection from direct midday sun in summer and must be moved indoors or wrapped if overnight temperatures drop below 10 °C in winter, as frost will damage the foliage and can kill the plant.
