Oh, this is my very sick Corralberry; and my newer healthy one. I dont know what the problem is. Ive had it longer than anything else just about. Maybe three years or so. And never had a problem w/ it before. My younger Corralberry is happy as can be. The big one started to drop leaves at a massive rate, and there is one stem (I dont know if you can see it in the pic) but it has lost everything. New ones first and sick one is the other two. I have not changed light, location, water, or fertilizer at all pretty much since I brought it home. I did repot it over a year ago and it took the event without fuss. However a few weeks or over a month ago by now I pulled it out of the pot and divided the root ball and the stems into three different sections but replaced all three back in the same pot with space between each. Now I would usually say this was the tramatising event but I did the same thing to the other Corralberry and it looks/acts uneffected by the whole thing.
