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.

A Leaning Tree

This is an Australian pine at least 5-6 yrs old and is over 20 ft tall and trunk is approx 5 inches in diameter. It grew straight but is now leaning.

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.
