Why Is My Monstera Turning Yellow?
Welcome to the lush world of Monstera, a favourite amongst plant lovers for its dramatic, Swiss-cheese-like leaves and easy-going nature. However, even the sturdiest plants can encounter issues, and yellowing leaves in Monsteras can leave many enthusiasts puzzled. Let’s unfold the reasons behind this discolouration and how you can restore the vibrant green health of your beloved plant.
Understanding the Causes of Yellowing Leaves
Yellow leaves can be symptomatic of several issues, ranging from natural aging to more concerning environmental or care mishaps. Identifying the cause is the first step to remedying the problem.
- Watering Issues: Both overwatering and underwatering can lead to your Monstera's leaves turning yellow.
- Light Exposure: Insufficient lighting or too much direct sunlight can also stress the plant, causing leaves to yellow and wilt.
- Nutrient Deficiency: A lack of essential nutrients, particularly nitrogen, can manifest as yellowing leaves.
- Pest Infestations: Pests like spider mites and mealybugs can drain your plant of its vital juices, leading to discoloured leaves.
Diagnosing and Fixing Watering Issues
Watering correctly is crucial for keeping your Monstera healthy. Here’s how you can ensure optimal watering:
| Condition | Action |
|---|---|
| Overwatering | Let the soil dry out before watering again; consider improving drainage by adding perlite or sand. |
| Underwatering | Establish a regular watering schedule. Water thoroughly until water runs from the drainage holes. |
Ensuring Proper Light Exposure
Monsteras prefer bright, indirect light. Too little light can weaken your plant, while too much direct sunlight can scorch the leaves, causing them to turn yellow. If you suspect lighting issues, try relocating your Monstera to a spot with indirect but bright light, or use sheer curtains to diffuse direct sunlight.
Addressing Nutrient Needs
A balanced diet is important for your Monstera. Utilise a balanced, water-soluble fertiliser every month during the growing season. If you notice yellowing leaves, consider whether your plant might be missing vital nutrients. Nitrogen deficiency, in particular, can cause yellowing. A supplement with a higher nitrogen content might be necessary.
Combating Pests
Regularly check your Monstera for signs of pests. If you find any, isolate the affected plant to prevent spread and treat it with an appropriate insecticide or natural remedy like neem oil. Keeping the leaves clean can also prevent pest infestations.
FAQs
Can temperature fluctuations cause my Monstera to turn yellow?
Yes, sudden changes in temperature or drafts can stress your plant, leading to yellowing leaves. Try to keep your Monstera in a stable environment away from draughty windows or heating vents.
Is it normal for old Monstera leaves to turn yellow?
Yes, it is natural for older leaves at the bottom of the plant to eventually turn yellow and die off as part of the plant’s growth process. This is normal and allows nutrients to be redirected to newer growth.
How often should I repot my Monstera?
Monsteras typically need to be repotted every 18-24 months. If your plant's growth seems stunted or the soil dries out too quickly after watering, it might be time to repot.

Yellowing leaves can be a sign that your Monstera is asking for help.
