About 2 wks ago, I planted a santa rosa japanese plum tree in my back yard. I am concered because the leafs look droopy. I have been watering it every day and don't know if I have perhaps over watered or under watered it. I also noticed that some of the leafs have small tiny holes on them and don't know if it may be a disease that is cousing the droopiness. I live in the high desert area of southern california but the weather so far has been very cool, windy and even cloudy. I know that these trees grow fine here as have heard of them and I was told by the nursery that they only bring plants that can.
