How to Grow Trachycarpus
Trachycarpus fortunei
Trachycarpus is the hardiest palm for temperate climates, forming a single fibrous trunk topped with large fan-shaped evergreen leaves. Plant in a sheltered spot protected from cold winds. Hardy to -10°C once established. Slow growing but eventually reaches 10-12 m. Remove dead lower fronds for a tidy appearance. Evergreen — no true leaf fall.
Yearly Lifecycle
Care Essentials
Apply a balanced slow-release fertiliser in spring as growth resumes. A palm-specific feed with added magnesium is ideal. Feed again in midsummer for vigorous specimens.
Watch For
- Cold wind damage to young leaves — shelter from north and east winds
- Yellowing lower fronds are natural — remove when fully brown
- Phytophthora (crown rot) in waterlogged conditions — ensure good drainage
- Scale insects on leaf undersides

☀️ Light
Full sun to partial shade in a sheltered position
Thrives in full sun but tolerates partial shade. The key requirement is shelter from cold drying winds rather than sun intensity — a sunny sheltered courtyard is ideal.
💧 Watering
Regular watering for first 2 years; established palms are fairly drought-tolerant
Water young palms weekly during dry spells in the first two growing seasons. Once established, Trachycarpus is reasonably drought-tolerant but appreciates irrigation during prolonged summer dry spells.
🌱 Fertilizing
Palm-specific slow-release feed in spring and midsummer
Apply a balanced slow-release fertiliser with added magnesium in mid-spring. A second application in midsummer benefits actively growing specimens. Avoid high-nitrogen feeds which produce soft, frost-vulnerable growth.
✂️ Pruning
Remove only fully dead brown fronds; never cut green or yellowing leaves
Cut dead fronds close to the trunk with loppers or a pruning saw. Leave the fibrous leaf bases on the trunk as insulation. Never remove green or yellowing fronds — they are still feeding the palm.
❄️ Overwintering
Wrap crown with fleece during severe frost; established palms are hardy to -10°C
Mature specimens with thick trunks are hardy to around -10°C. In areas prone to prolonged hard frost, wrap the growing crown (not the whole trunk) with several layers of horticultural fleece from November to March.
Growing Tips
Shelter from cold winds
Despite its cold tolerance, Trachycarpus dislikes persistent cold winds which shred and desiccate the fan leaves. Plant in a sheltered corner or use other shrubs as a windbreak, especially when young.
Leave the fibre on the trunk
The brown hair-like fibre covering the trunk acts as natural insulation. Never strip it off — it protects the growing point from frost and is part of the palm's ornamental character.
Slow and steady
Expect only 15–30 cm of new growth per year in the UK climate. Avoid overfeeding which can produce rapid, weak growth. Patience is rewarded with a genuinely exotic-looking specimen.
Only remove fully dead fronds
Never remove yellowing fronds — they are still photosynthesising and feeding the palm. Only cut fronds that are fully brown and dead. Premature removal weakens the tree.
Pests & Diseases
Pest Scale Insects
Identification: Small brown oval bumps on leaf undersides and petioles. Sticky honeydew and black sooty mould develop on fronds below infested areas.
- Wipe off with a cloth dampened in soapy water or use a soft brush.
- Apply horticultural oil spray in spring targeting crawlers on new growth.
- Systemic insecticide spray in late spring when crawlers are mobile.
Pest Red Spider Mite
Identification: Fine pale speckling and bronzing of frond surfaces; fine webbing under fronds in severe infestations; tiny red-orange mites visible with a hand lens.
- Mist the fronds regularly — mites thrive in dry conditions.
- Introduce predatory mites (Phytoseiulus persimilis) in greenhouse situations.
- Apply a fatty acid or plant oil-based miticide; repeat after 7 days.
Disease Phytophthora Crown Rot Phytophthora palmivora
Symptoms: Young fronds fail to unfurl and turn brown; older fronds yellow rapidly; the crown becomes soft and smells unpleasant; the palm collapses from the top.
Treatment: No effective cure once established. Remove and destroy the whole plant. Do not replant palms in the same waterlogged spot.
Prevention: Ensure excellent drainage — never plant in a waterlogged position. Raise the planting site or add grit if drainage is poor.
Disease Frond Yellowing
Symptoms: Progressive yellowing of lower fronds working upwards; fronds that have not fully opened begin to brown at the tips.
Treatment: Check for magnesium deficiency first — apply Epsom salts (magnesium sulphate) as a soil drench and foliar spray. If not nutrient-related, investigate drainage.
Prevention: Annual palm-specific fertiliser containing magnesium and trace elements prevents nutrient-related yellowing.
