Why Is My Monstera Turning Yellow?
Direct Answer
The most common cause of yellow Monstera leaves is overwatering, which causes root rot and prevents nutrient uptake. Other causes include too little light, nutrient deficiency, temperature stress, natural aging, repotting shock, and pest damage. Check the soil moisture first — if it's soggy, let it dry out completely before watering again.
1. Overwatering (Most Common)
Monsteras need their top 2 inches of soil to dry out between waterings. Constantly wet soil suffocates roots, leading to root rot. Yellowing starts with lower leaves and spreads upward.
Fix: Let soil dry completely, check for root rot, and repot if needed. See our detailed overwatered plant rescue guide.
2. Insufficient Light
Monsteras need bright indirect light. In low light, they can't photosynthesize efficiently, leading to yellow leaves and slow growth. Move to within 5 feet of a bright window. See our lighting guide for more detail.
3. Nutrient Deficiency
Yellowing between leaf veins (while veins stay green) usually indicates nitrogen or iron deficiency. Feed with a balanced liquid fertilizer monthly during spring and summer.
4. Temperature & Draft Stress
Monsteras prefer 65-85°F (18-30°C). Cold drafts from windows or AC vents cause rapid yellowing. Keep away from drafty spots and never expose to temperatures below 50°F (10°C).
5. Natural Aging
If only the oldest, lowest leaves are yellowing one at a time, this is normal. The plant naturally sheds old leaves to redirect energy to new growth. Simply trim them off.

Frequently Asked Questions
It's normal for the oldest, lowest leaves to yellow and drop as the plant grows — this is natural aging. However, if multiple leaves or newer leaves are yellowing, it indicates a care issue that needs attention.
Yes. Once a Monstera leaf has turned fully yellow, it won't recover. Cut it off at the base of the petiole with clean scissors to redirect the plant's energy toward healthy growth.
Signs of overwatering include consistently moist soil, yellow leaves (starting from the bottom), mushy dark brown spots, and a musty smell from the soil. Check if the pot has drainage holes and that you are letting the top 2 inches of soil dry between waterings.
