Pothos (Epipremnum aureum) is a popular houseplant known for its hardiness and lush green foliage. However, yellow leaves can be a sign of stress or improper care. Understanding the causes and solutions from the plant's perspective helps restore its health.
From the plant's viewpoint, yellowing leaves are a distress signal. Here are the primary causes:
Pothos roots need oxygen to function. Overwatering suffocates the roots, leading to root rot. The plant cannot absorb nutrients efficiently, causing leaves to yellow and wilt.
While Pothos tolerates drought, prolonged dryness stresses the plant. Leaves turn yellow as the plant conserves water and nutrients for survival.
If the potting mix retains too much water, roots stay soggy. This mimics overwatering conditions, triggering yellow leaves as the roots decay.
Pothos requires nitrogen, magnesium, and iron for healthy foliage. A lack of these nutrients disrupts chlorophyll production, leading to yellowing.
Insufficient light reduces photosynthesis. The plant sheds older leaves (turning yellow first) to redirect energy to new growth.
Pothos prefers 65–85°F (18–29°C). Cold drafts or sudden temperature drops can shock the plant, causing yellow leaves.
Spider mites or mealybugs drain sap from leaves, weakening the plant. Yellow spots or widespread yellowing may appear as a result.
Addressing the root cause is key. Here’s how to help your Pothos recover:
Water only when the top 1–2 inches of soil are dry. Ensure excess water drains freely from the pot to prevent root rot.
Use a well-draining potting mix with perlite or orchid bark. Repot if the current soil is compacted or waterlogged.
Apply a balanced liquid fertilizer every 4–6 weeks during the growing season. For magnesium deficiency, use Epsom salt (1 tsp per gallon of water).
Place Pothos in bright, indirect light. Avoid direct sun, which can scorch leaves, but ensure it receives enough light for photosynthesis.
Keep the plant away from AC vents, heaters, or drafty windows. A consistent room temperature promotes healthy growth.
Wipe leaves with neem oil or insecticidal soap. Isolate the plant to prevent pests from spreading to others.
Trim yellow or dead leaves to redirect the plant’s energy to healthy growth. Use sterilized scissors to avoid infection.
Monitor your Pothos regularly. Check soil moisture, light exposure, and leaf health to catch issues early. A consistent care routine ensures vibrant, green foliage.
