I purchased this Aralia Fabian at a small plant shop in Chinatown 1 week ago. I noticed the first day the soil was very wet and a few leaves were yellowing. As the week went on it lost more leaves so I brought it back to the shop. As I get out of the car the whole stump falls out of the pot! It looks like a bare nub with no real roots! The shop repot it, took zero responsibility. No refund or exchange kind of place. I spent close to $40 on this little tree and I want to know if anything can be done? Or does this plant sound sick? I have it quarantined from my other plants. I get plenty of light, temperature ranging from 65-70 degrees F.
