Hello all. This is my first post. My wife and I purchased a really nice weeping cherry. I have absolutely over watered this poor guy. I have learned my lesson. The soil is very good (no clay) and well drained (until I got out the hose). I am not sure if this can be saved? I pulled the mulch back and have stopped all watering. I am thinking of digging the soil back and removing the dirt around the root ball and replacing but not sure what to do. Currently I have put a few holes with a broom handle to try and dry it out. It rained like heck here so before it rained I put plastic over the root ball and left an opening around the trunk and covered the holes I made. Heres the pictures, Have I killed this once great tree? The tree is only 1 week old?
