Why is my Monstera Adansonii turning yellow
Monstera adansonii, also known as the Swiss cheese vine, is a fast-growing houseplant with delicate, perforated leaves. When leaves start turning yellow, it’s usually a sign that something in its care needs adjusting.
Catching the issue early helps prevent further damage and keeps the plant healthy.
Quick answer: why Monstera adansonii turns yellow
Monstera adansonii leaves turn yellow due to overwatering, poor drainage, low light, or environmental stress. Adjusting watering, improving light, and ensuring well-draining soil will resolve most problems.
Step-by-step guide to fixing yellow leaves
Step 1: Check watering levels
- Overwatering is the most common cause
- Allow the top layer of soil to dry slightly between watering
- Avoid consistently wet soil
Step 2: Inspect drainage and roots
- Ensure pots have drainage holes
- Check for signs of root rot (soft, dark roots)
- Repot into fresh, well-draining compost if needed
Step 3: Improve light conditions
- Place in bright, indirect light
- Avoid deep shade
- Avoid sudden exposure to strong direct sun
Step 4: Assess humidity and environment
- Prefers moderate to high humidity
- Avoid cold drafts or sudden temperature changes
- Keep conditions stable
Step 5: Review feeding and general care
- Feed lightly during the growing season
- Avoid overfeeding
- Remove fully yellow leaves
When yellowing is most likely
Yellow leaves often appear:
- After overwatering
- When moved to a new location
- During seasonal changes
- In low light conditions
Most common causes
Overwatering
- Leads to root stress and yellow leaves
Poor drainage
- Waterlogged soil damages roots
Low light
- Causes weak, pale growth
Low humidity
- Leads to stress and leaf decline
Natural ageing
- Older leaves yellow and drop
Ideal growing conditions
- Light
- Bright, indirect light
- Soil
- Free-draining houseplant compost
