Pack the soil down, and add any of the excavated soil back as needed to fill in the hole. You should be able to fill in the hole from the old location with the soil remaining from the new hole. You will need to prop your tree up, to protect it from winds until the roots have had a chance to grow and stabalize it. Water only if it is spring, otherwise, leave your tree alone until the spring, and see if it starts to put out new shoots. Do not fertilize for the first few months of new growth.
Excessive fertilizer can cause the tree to fail to produce enough new roots.
With a little bit of luck, your tree will be growing well the second year after transplanting. Inc. PageWise makes no representations about the content published on this site.
