Kentia Palm Prone to Leaf Tip Necrosis: How to Protect
Howea forsteriana
Leaf tip necrosis, also known as tip burn, is a non-infectious environmental condition where the tips and edges of leaves turn brown, dry, and crispy. This occurs due to various stress factors affecting the plant's ability to maintain healthy tissue at the leaf extremities.
ð Symptoms
- âĒ Brown or black discoloration at leaf tips
- âĒ Dry, crispy texture on affected areas
- âĒ Progressive browning from tip toward leaf base
- âĒ Dead tissue at leaf margins
- âĒ Tips may curl or become brittle
â Possible Causes
- â Salt and mineral buildup in soil from tap water
- â Low humidity levels, especially indoors
- â Inconsistent watering (both over and underwatering)
- â Calcium, magnesium, or potassium deficiency
- â Excessive light or heat exposure
- â Root damage or root-bound conditions
- â Fluoride or chlorine sensitivity from tap water
ð Treatment
Quick Fixes
Step 1
Check soil moisture immediately - water if dry, improve drainage if soggy
Step 2
Remove severely affected leaves to prevent stress
Step 3
Apply balanced liquid fertilizer at half strength
Step 4
Spray leaves with calcium-magnesium foliar solution
Step 5
Ensure proper air circulation around plant
Step 6
Move plant to location with appropriate light levels if needed
Organic Treatment
Step 1
Test soil pH and nutrient levels to identify deficiencies
Step 2
Apply organic mulch (2-3 inches) over root zone to retain moisture
Step 3
Improve drainage if soil is waterlogged
Step 4
Amend soil with compost or well-rotted organic matter
Step 5
Water consistently, keeping soil moist but not soggy
Step 6
Apply foliar spray of diluted seaweed extract or compost tea weekly
Step 7
Add organic calcium sources like crushed eggshells or bone meal if deficient
ðĄïļ Prevention
- â Use filtered, distilled, or rainwater instead of tap water
- â Maintain consistent watering schedule
- â Increase humidity with humidifier or pebble trays
- â Flush soil periodically to remove salt buildup
- â Ensure adequate calcium and magnesium in fertilizer
- â Provide appropriate light levels for species
- â Avoid placing plants near heating vents or AC
- â Let tap water sit 24 hours before use to dissipate chlorine

ð§ How to Water
Water when the top inch of soil feels dry, typically once a week. Reduce watering in winter. Avoid waterlogging as this can cause root rot. The Kentia is moderately drought-tolerant once established.
âïļ Lighting
Thrives in bright, indirect light but remarkably tolerant of low-light conditions. Avoid direct sunlight which can scorch the fronds. East or west-facing windows are ideal. Can adapt to north-facing rooms.
ðŠī Ideal Soil
Use a well-draining, slightly acidic to neutral potting mix (pH 6.0-7.0). A palm-specific mix or general potting soil amended with perlite or sand works well. The roots are sensitive to disturbance, so repot only when severely rootbound.
