Question
In July it was necessary for me to have a Blue Spruce moved due to it being planted on the property line where a fence was to be erected.  The tree was transplanted and I was told to water it twice a day be filling the trough which had been made around it with the dirt.   I did this all summer and the tree seemed to flourish.  Suddenly, in late September I noticed the needles becoming brown.  I was told to continue watering it.   I have done so, but am concerned that the tree may be dying.  Someone suggested using Preen, but I have done nothing but water it so far.  Any information you can give me will help.  Thanks.

Answer
I think it was over watered--trees need about 1 inch of water per week. This can be done by putting a pan under the tree and turning the sprinkler on and when the pan has 1 inch of water in it stop. Over watering can be as bad for a tree as too little watering. I would lay off the water and water only if it does not rain for 10-14 days or so.
