Is your Amazon Sword showing yellow leaves? Discover 5 possible causes and how to treat them.
🔍 Possible Causes (5)
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

Nutrient Deficiency
Nutrient deficiency occurs when a plant cannot access one or more essential mineral elements in sufficient quantities for healthy growth. Plants require 17 essential nutrients: macronutrients (N, P, K, Ca, Mg, S) and micronutrients (Fe, Zn, Mn, Cu, B, Mo, Cl). Each plays a unique role in metabolism, structure, and reproduction. Deficiencies arise from depleted soils, incorrect pH blocking uptake, poor watering practices leaching nutrients, root damage, or imbalanced fertilization. Understanding whether a nutrient is mobile or immobile determines where symptoms first appear: mobile nutrients (N, P, K, Mg) show symptoms on older leaves first, while immobile nutrients (Ca, Fe, Zn, Cu, B) show symptoms on new growth first.
✓ Related symptoms:
- • Nitrogen (N): overall yellowing starting from older/lower leaves, progressing upward; slow stunted growth; pale lime-green foliage
- • Magnesium (Mg): interveinal chlorosis on older leaves (veins stay green while tissue yellows); leaves may curl upward; premature leaf drop
Potassium Deficiency
Potassium deficiency is a nutritional disorder that affects a plant's ability to regulate stomatal opening and closing, resulting in characteristic leaf edge burn. Potassium is a mobile nutrient, so symptoms first appear on older, lower leaves.
✓ Related symptoms:
- • Yellow or brown scorching along leaf margins
- • Chlorosis (yellowing) between leaf veins

Crown Rot
Crown rot is a serious fungal disease that attacks the crown (base) of the plant where the stem meets the soil. It is caused by various fungal pathogens including Phytophthora, Fusarium, and Rhizoctonia. The disease thrives in waterlogged conditions and can quickly spread to kill the entire plant if not addressed promptly.
✓ Related symptoms:
- • Yellowing of lower leaves that drop prematurely
⚡ Quick Fixes:
Immediate unpotting
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.
