A week ago I received a beautiful olive bonsai tree as a present from my family (I have a pic but I don't know how to post it). It came with no instructions so I don't know what kind it is or how to care for it. I was just told that it was 18 years old and the more sun it gets the redder the new growth. This wasn't much help. To make things worse, the ride home was bumpy most of the way. I was afraid it would drop its leaves. I put it in a window with lots of morning sun. I was away for a couple days and mom neglected to water it while I was gone. I came back and it was very dry. All the new growth dried up and leaves have been falling off since Sunday. I haven't seen many posts regarding olive trees, so I'm hoping that someone can offer some advice? Can I save the tree? What steps should I take and how do I care for it in the future?
