How to Grow Coconut Palm
Cocos nucifera
Coconut palms are strictly tropical and cannot survive outdoors in the UK. They require constant warmth (above 20°C year-round), high humidity, and full sun. In Britain they can only be grown as ornamental houseplants or in large, heated tropical glasshouses, and will not produce fruit under these conditions. If growing as a novelty, use a free-draining, sandy compost, keep warm and moist, and provide as much light as possible.
Yearly Lifecycle
Care Essentials
Feed monthly with a balanced liquid fertiliser during the growing season, reducing to every 6–8 weeks in winter. Add a magnesium supplement regularly as palms are prone to deficiency.
Watch For
- Red spider mite on frond undersides in dry conditions
- Scale insects on frond stems
- Mealybugs at frond bases and in leaf axils
- Root rot from overwatering or poor drainage
- Leaf spot in humid poorly ventilated conditions

☀️ Light
Maximum bright light; south-facing ideal
Full bright light is essential. Place in the brightest spot available — a south-facing conservatory or heated glasshouse. Coconut palms will not thrive in low light.
💧 Watering
Regular watering; mist for humidity
Water regularly and keep soil moist but never waterlogged. Use free-draining sandy compost and never let pots sit in water. Mist fronds regularly to raise humidity.
🌱 Fertilizing
Monthly liquid feed; add magnesium
Feed monthly with a balanced liquid fertiliser during the growing season. Reduce to every 6-8 weeks in winter. Palms benefit from added magnesium.
❄️ Overwintering
Above 20°C year-round; no cold tolerance
Maintain above 20°C year-round. Coconut palms cannot tolerate any cold and will decline rapidly below 15°C. A heated glasshouse is essential in the UK.
Growing Tips
Not viable outdoors in the UK
Coconut palms need year-round tropical heat and cannot tolerate any frost. In Britain, treat them as tender houseplants or heated glasshouse specimens only.
Maximise light and warmth
Place in the brightest spot available and maintain temperatures above 20°C. Mist regularly to raise humidity around the foliage.
Use free-draining compost
Plant in a sandy, well-drained mix and water regularly but never let the pot sit in water. Coconut palms are salt-tolerant but rot in waterlogged soil.
Pests & Diseases
Pest Red Spider Mite
Identification: Fine webbing on frond undersides, stippled yellowing fronds, tiny mites visible with a hand lens
- Increase humidity by misting regularly
- Introduce predatory mite Phytoseiulus persimilis under glass
- Spray with fatty acid-based miticide, ensuring good coverage of frond undersides
Pest Scale Insects
Identification: Small brown or white bumps on frond stems and undersides, sticky honeydew
- Wipe off with a cloth dipped in soapy water
- Introduce parasitic wasps as biological control under glass
- Spray with plant oil-based insecticide
Pest Mealybug
Identification: White cottony masses at the base of fronds and in leaf axils
- Dab with a cotton bud soaked in methylated spirit
- Introduce Cryptolaemus ladybird as biological control
- Spray with fatty acid or plant oil-based insecticide
Disease Root Rot Phytophthora palmivora
Symptoms: Yellowing and browning fronds, soft mushy base, plant collapse
Treatment: Remove from pot, trim rotten roots, repot in fresh free-draining sandy compost. Reduce watering
Prevention: Use very well-drained sandy compost. Never let pots sit in water
Disease Leaf Spot
Symptoms: Brown or black spots on fronds, sometimes with yellow halos, leading to frond dieback
Treatment: Remove affected fronds. Improve air circulation and reduce humidity around foliage
Prevention: Avoid overhead watering. Ensure good ventilation
Popular Varieties
Fiji Dwarf
Considered a true dwarf with thicker trunk and shorter fronds than Malayan. Highly ornamental and robust against strong winds.
Malayan Dwarf
A widely planted variety resistant to Lethal Yellowing disease. Begins bearing at a younger age than tall varieties and is easier to harvest.
