How to Grow Kentia Palm
Howea forsteriana
Kentia palm is one of the most elegant and forgiving houseplants, tolerating low light, infrequent watering, and a degree of neglect that would kill most plants. It prefers bright indirect light but adapts well to shadier rooms, making it ideal for hallways and offices. Water when the top 3 cm of soil feels dry and use rainwater or filtered water to avoid brown leaf tips from fluoride. Feed sparingly — over-fertilising is a more common problem than under-feeding.
Yearly Lifecycle
Care Essentials
Feed monthly with a palm fertiliser during spring and summer only. Kentia palms are slow feeders — avoid over-fertilising which causes brown leaf tips and salt build-up in the compost.
Watch For
- Red spider mite in dry conditions
- Scale insects on fronds
- Mealybug
- Root rot from overwatering

☀️ Light
Bright indirect light; tolerates low light.
Kentia palm thrives in bright indirect light but is one of the few houseplants that genuinely tolerates low-light rooms. Avoid direct sun, which scorches the fronds.
💧 Watering
Water when the top 3 cm of compost feels dry.
Allow the top 3 cm of compost to dry out before watering thoroughly, then let excess drain away. Reduce watering significantly in winter. Use rainwater or filtered water to prevent fluoride browning.
🌱 Fertilizing
Feed monthly in spring and summer only.
Apply a balanced liquid palm fertiliser at half strength once a month from April to August. Do not feed in autumn or winter, and never exceed the recommended dose — salt build-up causes brown tips.
✂️ Pruning
Remove only fully brown and dead fronds.
Cut dead fronds at the base with clean scissors. Do not remove fronds that are only partially brown — the plant reabsorbs nutrients from them. Never cut into green fronds unnecessarily.
🌿 Humidity
Prefers moderate to high humidity; mist or use a pebble tray.
Kentia palms prefer humidity above 50%. In centrally heated UK homes, provide humidity by placing the pot on a pebble tray filled with water, grouping with other plants, or misting the fronds occasionally — especially in winter.
Growing Tips
Use rainwater or filtered water
Tap water fluoride and chlorine are a leading cause of brown leaf tips in kentia palms. Collect rainwater or leave tap water to stand overnight before using, and switch to filtered water if browning persists.
Never repot unless rootbound
Kentia palms dislike disturbance and grow slowly — repotting too frequently stresses the plant unnecessarily. Only move up one pot size when roots are visibly circling the base or growing through drainage holes.
Wipe the fronds
Dust accumulates on broad palm fronds and blocks light. Wipe both sides of each frond with a damp cloth every few weeks to keep the plant photosynthesising efficiently and looking its best.
Keep away from heat sources
Radiators, sunny windowsills, and hot air vents cause rapid drying of fronds and brown tips. Position the palm at least 1 m from any direct heat source and away from cold draughts.
Pests & Diseases
Pest Red Spider Mite
Identification: Fine webbing on fronds and between leaflets; tiny red or yellow mites visible under a magnifying glass; fronds develop a pale, stippled appearance.
- Increase humidity around the plant — mites thrive in dry air.
- Wipe fronds with a damp cloth to physically remove mites and webbing.
- Spray with neem oil solution, covering all frond surfaces.
- Apply a proprietary miticide such as a pyrethrin-based spray, following label directions.
Pest Scale Insects
Identification: Small brown or cream waxy bumps on frond stems and the undersides of leaflets; sticky honeydew deposits on lower fronds and surrounding surfaces.
- Scrape off individual scales with a soft toothbrush or cotton swab dipped in rubbing alcohol.
- Apply neem oil spray to all frond surfaces monthly until clear.
- Use a systemic houseplant insecticide containing imidacloprid applied to the compost.
Pest Mealybug
Identification: White fluffy wax deposits in leaf axils and on frond stems; sticky honeydew and sooty mould may follow heavy infestations.
- Dab individual bugs with a cotton swab soaked in rubbing alcohol.
- Spray with insecticidal soap solution, paying attention to leaf axils.
- Apply a systemic insecticide drench to the compost.
Disease Root Rot Phytophthora spp. / Pythium spp.
Symptoms: Fronds yellow from the base upwards; plant appears wilted despite moist compost; roots are brown and mushy rather than white and firm when inspected.
Treatment: Remove the plant from its pot, trim all brown mushy roots back to healthy tissue, and repot into fresh free-draining compost. Allow compost to dry further between waterings going forward.
Prevention: Never allow the plant to sit in standing water. Use a pot with drainage holes and a free-draining palm or houseplant compost.
Disease Fungal Leaf Spot Helminthosporium spp.
Symptoms: Small brown or yellow spots with darker borders on the leaflets, which may enlarge and merge in severe cases.
Treatment: Remove heavily affected fronds at the base. Improve air circulation and reduce overhead watering. A copper-based fungicide can be applied if the problem persists.
Prevention: Avoid wetting the foliage when watering. Ensure the plant is not in a stagnant, poorly ventilated position.
