Areca Palm with Yellow Leaves: Causes and Solutions
Dypsis lutescens
Is your Areca Palm showing yellow leaves? Discover 10 possible causes and how to treat them.
🔍 Possible Causes (10)
Leaf Spot
Leaf spot is a common fungal disease caused by various pathogens including Alternaria, Ascochyta, Colletotrichum, Septoria, and Venturia. It primarily affects leaves, causing discolored spots that can lead to premature leaf drop if left untreated.
✓ Related symptoms:
- • Circular brown, gray, black, or yellow spots on leaves
- • Yellow halo surrounding spots
⚡ Quick Fixes:
Remove all visibly infected leaves
Scale Insects
Scale insects are small sap-sucking pests that appear as brown, shell-like bumps on plant stems and leaves. There are over 25 species, divided into armored (hard) and unarmored (soft) scales. They feed by piercing plant tissue and extracting sap, which weakens the plant and can lead to yellowing, stunted growth, and even death if left untreated. They also excrete honeydew, which attracts ants and promotes sooty mold growth.
✓ Related symptoms:
- • Yellowing or chlorotic (pale) leaves

Step 1
Overwatering
Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.
✓ Related symptoms:
- • Yellow or brown limp, droopy leaves that feel soft and mushy
- • Dropping leaves (both old and new) that may be green, brown, or yellow
- • Brown spots or edges with yellow halos on leaves (bacterial infection)

Salt Buildup
Salt buildup (also called salt accumulation or fertilizer salt deposits) is an environmental condition where mineral salts accumulate in the soil over time, creating a toxic environment for plant roots. The most visible sign is a white or yellowish crusty layer on the soil surface or around pot edges.
✓ Related symptoms:
- • White or yellow crystalline buildup around pot edges
- • Yellowing leaves (chlorosis)

Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.

- • Yellowing or browning of leaves

Emergency unpotting
Southern Blight
Southern blight is a devastating soilborne fungal disease caused by Athelia rolfsii (formerly Sclerotium rolfsii), affecting over 500 plant species including vegetables, ornamentals, and fruit crops. The fungus survives in soil through resting structures called sclerotia that resemble mustard seeds and can remain viable for years.
✓ Related symptoms:
- • Yellowing and necrosis of foliage
- • On fruits: sunken yellow lesions turning water-soaked

Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
✓ Related symptoms:
- • Tiny yellow or white speckles on leaf surface (stippling)
- • Leaves taking on yellow or bronzed appearance

Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.
✓ Related symptoms:
- • Yellowing or wilting leaves
⚡ Quick Fixes:
Step 1
Underwatering
Underwatering or drought stress is a physiological disorder that occurs when the amount of water a plant loses through transpiration exceeds the amount its roots can absorb from the soil. This leads to cellular dehydration and various visible symptoms that can compromise plant health and productivity.
✓ Related symptoms:
- • Yellowing leaves, especially older ones (chlorosis)
⚡ Quick Fixes:
Step 1
Chemical Burn
Chemical burn (phytotoxicity) occurs when plants are damaged by misapplication or misuse of pesticides, herbicides, fertilizers, or other chemicals. Environmental conditions like high temperatures, humidity, and plant stress increase vulnerability. Unlike diseases, chemical damage is not contagious but can severely harm or kill plants if not addressed promptly.
✓ Related symptoms:
- • Browning or yellowing of leaf margins and tips
- • Chlorosis (yellowing) from herbicide exposure
