How to Grow Rubber Plant
Ficus elastica
Rubber plants grow best in bright indirect light and dislike being moved — find a good spot and leave them there. Water when the top 3–4 cm of compost dries out and feed monthly from April to September. Wipe the large glossy leaves with a damp cloth occasionally to keep them dust-free. They can reach ceiling height indoors, so choose your location with their potential size in mind.
Yearly Lifecycle
Care Essentials
Feed monthly with a balanced liquid fertiliser from April to September. Reduce to every 6–8 weeks in autumn and stop feeding entirely over winter.
Watch For
- Scale insects on stems and leaf undersides
- Mealybugs in leaf axils
- Glasshouse red spider mite in dry conditions
- Root rot from overwatering
- Leaf drop from cold draughts or sudden temperature changes

☀️ Light
Bright indirect light preferred
Place in bright indirect light — a few metres from a south or west-facing window is ideal. Direct sun scorches leaves; deep shade causes leggy growth and leaf drop.
💧 Watering
Water when top 3–4 cm of compost dries out
Allow the top third of the compost to dry between waterings. Reduce to every 2–3 weeks in winter. Always use room-temperature water and ensure the pot drains freely.
🌱 Fertilizing
Monthly feed April to September
Feed with a balanced liquid fertiliser monthly during the growing season. Stop feeding from October to March when the plant is resting.
✂️ Pruning
Prune in spring to control height
Trim back in spring to keep the plant at a manageable size and encourage bushier branching. Wear gloves — the milky latex sap is a skin irritant and can stain fabrics.
🌿 Humidity
Moderate humidity preferred
Rubber plants prefer moderate to high humidity. Wipe leaves with a damp cloth to remove dust and improve moisture uptake. Keep away from dry radiator heat, which causes brown leaf tips.
Growing Tips
Find the right spot and leave it
Rubber plants dislike being moved — every relocation causes leaf drop. Choose a position in bright indirect light away from radiators and cold draughts, then leave the plant there permanently.
Wipe the leaves regularly
The large glossy leaves collect dust quickly, reducing photosynthesis. Wipe them monthly with a damp cloth or soft sponge to keep them clean and shiny.
Water less than you think
Most rubber plants are overwatered. Let the top 3–4 cm of compost dry out completely between waterings. In winter, reduce further to every 2–3 weeks. Yellow leaves usually mean too much water, not too little.
Propagate from cuttings or air layering
Rubber plants can be propagated from tip cuttings in spring — dip in rooting hormone and keep warm and humid. For larger plants, air layering produces a well-rooted new plant without severing the stem.
Pests & Diseases
Pest Scale Insects
Identification: Brown or tan oval bumps on stems and leaf undersides that don't move; sticky honeydew on leaves below; sooty mould may develop.
- Wipe off with a cotton bud or soft cloth dipped in rubbing alcohol.
- Spray with insecticidal soap, ensuring coverage of stems and leaf undersides.
- Apply a systemic houseplant insecticide containing acetamiprid or imidacloprid.
Pest Mealybugs
Identification: White waxy cottony clusters in leaf axils and along stems; leaves become sticky and may yellow.
- Dab individual colonies with a cotton bud soaked in methylated spirits.
- Spray the whole plant with insecticidal soap every 5–7 days for several weeks.
- Use a systemic insecticide labelled for houseplants containing acetamiprid.
Pest Glasshouse Red Spider Mite
Identification: Fine pale stippling on upper leaf surface; tiny webs under leaves and in leaf axils; leaves may bronze and drop.
- Mist leaves regularly with water — spider mites thrive in dry air.
- Introduce predatory mite Phytoseiulus persimilis for persistent infestations.
- Spray with a miticide or insecticidal soap, repeating every 7 days for three applications.
Disease Root Rot Pythium spp. / Phytophthora spp.
Symptoms: Yellowing lower leaves; stems feel soft at base; roots appear brown, mushy, and smell unpleasant when checked.
Treatment: Remove from pot, cut away all rotted roots, dust cuts with sulphur, and repot in fresh well-draining compost. Reduce watering frequency.
Prevention: Always use pots with drainage holes. Never leave standing in water. Allow the top layer of compost to dry between waterings.
Disease Leaf Drop (non-disease) Environmental stress
Symptoms: Sudden loss of multiple leaves; plant looks healthy but drops leaves in a short period.
Treatment: Identify and remove the stressor — most commonly a move to a new location, cold draught, or sudden temperature change.
Prevention: Keep away from doors, draughty windows, and radiators. Avoid moving the plant once it is settled.
