I have a bunch of new ones also. 4 from one supplier. 3 have died. One left seems to have a similar problem but it has leaves and looks healthy except for the steam a little darker and close to the dirt a little softer than the top of the plant. I had these for 3 weeks. When they arrived they did not have much of a root system in comparison to others I've gotten from other suppliers. I will no longer order from this supplier.

if the base/trunk is firms and its the branches, then i guessing not enough water.

how are the leaves?

how much and how often are you watering?

what size pots?

i have mine in 7 gallon pots, they're in full sun. i water them almost everyday, drenching/soaking the soil mix thoroughly.

pictures would help too.
