New leaves on indoor plant dying

Question

I recently purchased a chocolate mint plant about a week and a half to two weeks ago. I haven’t watered it at all since I got it because the pot it is in has no drainage and the soil is relatively moist. In the past I have killed plants by overwatering so I prefer to stay on the safe side of that. I’ve heard that it’s easier for plants to come back from underwatering than from overwatering. Most of the plant looks perfectly healthy, but the baby leaves coming in are brown and dead and the new leaves under those are yellowing towards the stem. I’m not sure what’s wrong; most information about brown or yellowing leaves has to do with brown and yellowing lower leaves, and those all look fine. What on earth could I possibly be doing wrong this time? Thank you for your time.

Answer 1

Your plant needs to have a well draining container, if the water stands in the pot, it eventually will kill it due to root rot.
Your plant also needs a full sun spot to do well indoors. A south facing window is good, or you could choose to add a grow light.
