In May we purchased two Japanese Maples and planted them just like it said in the instructions. They were doing fine until the leaves turned brown on one and looked dead except the trunk is green. The other one got bagworms on it I picked all the bagworms off and then sprayed it with the bagworm killer just like it said to .But now we don,t know what to do.

Please help.

I think your trees are suffering from some transplant shock and trying to deal with the summer weather so they probably are stressed. Wilting and/or dropping leaves are common signs. I think the bagworm attack was unfortunate but it sounds as though you've gotten them under control. There's not much you can do for the transplant shock other than to keep your trees watered on a regular basis. The roots will establish themselves and you'll see new growth later in the season. If you haven't already, make a watering well or watering basin beneath each tree. I just mound up 2-3 inches of soil in a circle around the tree, 12" away from the trunk. Water by flooding the basin, allowing it to drain, then flooding it a second time. This concentrates the moisture over the root mass and allows it to trickle down slowly and wet the entire root mass. Water your trees twice a week when the weather is hot; once a week if the weather is cool. I think you'll see some improvement soon. Best wishes with your trees.
