I need some help with a new Kousa Satomi Dogwood tree that I just planted. I bought it on 5/25/06 and it was planted on 5/26/06. The day I bought it I watered the burlap that the roots were wrapped in so it wouldn't dry out. I had a man plant it for me and he did remove all the twine and loosen the burlap around the top of the root ball when he planted it. I was told by the nursery I got it at that once it was planted to just water it once a week. I did that for the next week, but the flowers quickly died and have since fallen off and some of the leaves started to turn brown and die. I have since started to water daily hoping to revive it, but it doesn't seem to be helping. I am in Northern Virginia and the tree is in Full Sun in my front yard. My question is basically what can I do to try to ensure that it doesn't die and to get it to thrive as much as possible. Should I try any specific fertilizers? Should I be watering more/less? This is my first time ever planting a tree and I am very worried about this Dogwood! Thanks to you all for any help you can offer.
