Is your Floating Fern showing yellow leaves? Discover 6 possible causes and how to treat them.
🔍 Possible Causes (6)
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
✓ Related symptoms:
- • Clusters of soft-bodied insects in various colors (green, black, red, yellow)
- • Curled, distorted, or yellowing leaves

Nitrogen Deficiency
Nitrogen deficiency occurs when plants lack sufficient nitrogen, an essential macronutrient needed for chlorophyll production and overall growth. This deficiency typically manifests as yellowing leaves, starting with older foliage and progressing to newer growth if left untreated.
✓ Related symptoms:
- • Yellowing (chlorosis) of older, lower leaves first
- • Pale yellow-green coloration across the entire plant
- • Some species may develop purple or reddish tints instead of yellowing

Step 1
Iron Deficiency
Iron deficiency, commonly known as iron chlorosis, is a nutrient deficiency disorder where plants cannot access sufficient iron from the soil. While iron is typically abundant in soil, various soil conditions can limit plant uptake, resulting in characteristic yellowing of leaves while veins remain green.
✓ Related symptoms:
- • Yellowing of leaves (chlorosis) while veins remain green - most obvious symptom
- • Yellowing starts at the tips of new growth and progresses to older leaves
- • Severe cases show yellowing even in leaf veins

Step 1
Soil pH Imbalance
Soil pH imbalance occurs when soil becomes too acidic (low pH < 6.0) or too alkaline (high pH > 7.5), preventing plants from absorbing essential nutrients. The ideal pH range for most plants is 6.5-7.5. When pH is outside this range, nutrients become chemically locked in the soil, leading to deficiency symptoms even when nutrients are present.
✓ Related symptoms:
- • Yellowing of older leaves with low pH (acidic soil)

Step 1
Low Light Stress
Low light stress, also known as etiolation, occurs when plants do not receive adequate light for proper growth and development. This leads to abnormal growth patterns characterized by elongated stems, pale leaves, and weakened overall structure as the plant attempts to reach toward available light sources.
✓ Related symptoms:
- • Pale, yellowish, or washed-out leaf coloration
- • Yellowing and dropping of older leaves

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.
