# Is my new leaf dying?? :( I got this monstera plant from a friend…

Is my new leaf dying?? :(  
I got this monstera plant from a friend back in April. It was doing so well and started to sprout a new leaf! But I have an issue of fungus gnats that I’ve been trying to get rid of. 18 days ago I watered with hydrogen peroxide solution to naturally kill the gnats. They were still around and I was worried about larvae in the soil so 9 days ago I watered with mosquito bits. But my new leaf is turning yellow and browning. What does that mean? I feel like I want to repot my plant with new soil but I’m afraid of putting it into shock. Per the mosquito bit instructions I should water with that solution again, but I’m afraid of overwatering. Should I mist the soil instead?  
Please help me save my new leaf!🙏

Hmm! The pot looks really big for the plant, so I’m thinking it’s being overwatered and that’s why that new leaf is dying.

I was wondering if the pot was too big.. I thought it would allow room for the plant to grow. But maybe it’s retaining too much water?

When a pot is too large for a plant the plant focuses on growing the roots rather than new leaves. The pot should be about an inch bigger than the root ball. I would take it out of that pot, rinse the roots, and put it in a smaller pot with fresh soil.

Yep! Definitely… check the root ball. Cut off any black mushy roots and downsize into a smaller pot. What size is the pot now?

For reference my largest monstera is in a 10in pot and I’m about to pot up… don’t mind her sadness right now lol I’ll water her soon 😅
