Yellowing leaves on your Monstera obliqua can be a sign of a few common issues. If you last watered it two weeks ago, it might be too dry—Monsteras prefer slightly moist soil. Check the soil, and if it feels dry a couple of inches down, give it some water. Also, make sure it’s getting bright, indirect light, as too much direct sunlight or too little light can stress the plant. Lastly, try increasing humidity by misting the leaves or using a humidifier. These adjustments should help your plant recover!
