Help! I bought this peperomia on facebook from a plant group and I’ve had it for about 2 weeks now and it is not doing well at all. A few days after I got it, I discovered it had gnats in the soil so I repotted it and covered the new soil in neem oil to keep them away. I water it every week or so, according to my planta schedule, but it keeps losing leaves and doesn’t seem to be getting any better. Any advice?
