Winter is a time of rest and renewal for your trees. There are still tasks you can do during this time.
As long as the ground is not frozen, you can still plant trees. They will have an easier time with the cool temperatures and rainfall.
Take care when watering in winter. In cold climates, only water mid-morning when both the air and soil temperatures rise above 40F and the snow has melted.
You can continue watering in mild climates, though you will likely not need to much since rain is common.
In mild climates, you can fertilize if soil tests show a need. Otherwise, in cold climates, don't fertilize until spring.
As always, remove any dead, diseased or damaged branches to keep the tree healthy. You can also do corrective pruning to shape the tree. However, if the tree flowers in the spring, prune lightly since next spring's flower buds are already on the branches.
