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
