Q. Transplanting a Tree

I just transplanted a nearly 6-foot Australian Pine that was in a pot. I followed instructions from another web site I saw, but my question is how long after transplanting it will I know if it is ok or dying?

Newly planted trees are vulnerable for up to a year after they are planted. If it does fine for a year, then you can consider it established. For the next year, look for yellowing or dropping needles to indicate if the tree might be failing.

Austrian Pine trees are quite disease resistant but they can become infected with a root feeding nematode.
Phytophthora and Hetrobasidion root rots.
Have you had excessive rain to loosen the ground and root system?
With the size of tree your dealing with I would certainly have a professional arborist look at the tree to determine the best coarse of action.
