We planted our first tree, a 6' Japanese Maple in our Front Yard 5 days ago. My husband planted the tree with a gardener. He watered the tree for 2 days then left for a 2 month business trip. Before he left, I was told to water the tree twice a day, and make sure the soil feels moist at all time. I found many wilted leaves on my first day of taking care of this tree. I watered the tree as instructed for 2 days. I found more wilted leaves. Many have fallen off. I asked the gardener for help yesterday. He said I have not given it enough water. He watered the tree for me yesterday. This morning, I found almost 50% of the leaves on the ground, even the green ones. Does anyone know what had happened?? Is this tree going to die?? HELP!
