Wait until trees and shrubs drop their leaves or undergo color change before planting them or digging and moving them to new sites. At that time they are entering dormancy and will not suffer as much transplant shock when moved.

Broadleaved and needled evergreens, both dwarf and standard, are best planted or moved by October 1. Water deeply and thoroughly at planting time and each week up until the ground freezes.

Continue to water large trees and shrubs, especially evergreens, until the ground freezes hard. Evergreens continue to lose moisture through their needles throughout winter and must have adequate water in their root zones to avoid winter burn or dessicated needles.

Wait until next month to fertilize any tree or shrub that looks like it might benefit from extra nutrition — for example, has stunted growth, has failed to fully flower or leaf out, or has undersized fruit or off-color foliage.
