Whether you’re a beginner or a seasoned grower, understanding these issues will help you restore your monstera’s health. For more plant care advice, visit Monstera Haven.
Causes of Yellowing Leaves
Yellow leaves can result from several factors, including watering mistakes, light issues, or nutrient imbalances. Here’s a breakdown of the most common causes.
Overwatering: Too much water is the leading cause of yellowing. Wet, soggy soil can lead to root rot, which prevents roots from absorbing nutrients, causing leaves to yellow. Check if the soil stays wet for days or if the pot lacks drainage holes.
Underwatering: Conversely, not watering enough can stress your monstera, leading to dry, yellow leaves. If the soil is bone-dry or leaves feel crispy, your plant may be thirsty.
Improper Light: Monsteras need bright, indirect light. Too little light can cause leaves to yellow and growth to slow, while direct sunlight can scorch leaves, leading to yellow or brown spots.
Nutrient Deficiency: A lack of essential nutrients, like nitrogen, can cause older leaves to yellow. This often happens if the plant hasn’t been fertilized or is in old, depleted soil.
Pests or Disease: Pests like spider mites or scale, or fungal issues like root rot, can cause yellowing. Look for webbing, sticky residue, or mushy roots as signs of trouble.
Step-by-Step Fixes for Yellow Leaves
Once you identify the cause, follow these steps to fix yellowing leaves and revive your monstera.
Step 1: Check Watering: Feel the top 1–2 inches of soil. If it’s soggy, let it dry out before watering again, and ensure the pot has drainage holes. If dry, water thoroughly until water drains out, then adjust to a regular schedule (every 7–10 days in growing season, 10–14 in winter).
Step 2: Inspect Roots: If overwatering is suspected, gently remove the plant from its pot. Trim brown, mushy roots with sterilized scissors and repot in fresh, well-draining soil (potting soil, perlite, orchid bark). For underwatered plants, soak the soil and monitor moisture going forward.
Step 3: Adjust Light: Move your monstera to a spot with bright, indirect light, like near a north- or east-facing window. If light is low, add a grow light for 8–12 hours daily. If leaves are scorched, use a sheer curtain to filter direct sun.
Step 4: Fertilize: If nutrient deficiency is likely, feed with a balanced, half-strength fertilizer (10-10-10) every 3–4 weeks during spring and summer. If the soil is old (over 1–2 years), repot with fresh mix to restore nutrients.
Step 5: Treat Pests or Disease: If pests are present, wipe leaves with a neem oil solution (1 teaspoon neem oil, 1 quart water, a few drops dish soap) every 5–7 days for 2–3 weeks. For fungal issues, remove affected roots or leaves and improve air circulation.
Step 6: Prune Yellow Leaves: Trim fully yellow leaves at the base with clean scissors to focus energy on healthy growth. Don’t remove more than 20% of leaves at once to avoid stress.
Preventative Care to Avoid Yellowing
Preventing yellow leaves is easier than fixing them. These tips will keep your monstera healthy long-term.
Consistent Watering: Water when the top 1–2 inches of soil are dry, using a moisture meter if needed. Ensure proper drainage to avoid water buildup.
Optimal Light: Place your monstera in bright, indirect light and rotate it every 1–2 weeks for even exposure. Clean leaves regularly to maximize light absorption.
Regular Fertilizing: Feed every 3–4 weeks during the growing season (spring–summer) with a balanced fertilizer. Stop in fall and winter unless the plant is under grow lights.
Pest Checks: Inspect leaf undersides and stems weekly for pests. Quarantine new plants for 2–3 weeks to avoid introducing issues.
Repotting: Repot every 1–2 years to refresh soil nutrients and prevent root-bound conditions. Use a well-draining mix to support healthy roots.

When to Seek Further Help for Your Plant
If yellowing persists despite fixes, you may need extra help to save your monstera.
Persistent Yellowing: If leaves continue to yellow after adjusting water, light, and nutrients, consult a local nursery or plant expert. They can diagnose rare issues like soil pH imbalances or advanced root rot.
Severe Pest Infestations: If pests don’t respond to neem oil or soap treatments, a professional may recommend stronger solutions or identify resistant species.
No Improvement: If the plant shows no new growth or worsens after 4–6 weeks, consider taking a healthy cutting to propagate a new plant. This can save part of your monstera if the main plant is too far gone.
Online Resources: Join plant care forums or social media groups for advice from experienced growers. Sharing photos can help others pinpoint the issue.
