I just bought a corn plant about two months ago. The leaves just started turning brown on the edges,and moving up.This is hurting me to see this.I love all my plants,and I try so hard to take good care of them.
Also,I had heard it is good to put mineral oil on the leaves,is this so? Someone please answer!!!

hiyas! mineral oil is bad for plants because it clogs it pores and makes dust collect quick
maybe you can try misting the plant more often and use distilled water not tap water.
good luck cass
