Water plants, especially evergreens, before the ground freezes.
Prune trees and shrubs in winter when the branches are without leaves. Remove waterspouts, dead, or crossing branches.
Apply winter mulch to perennials and roses after a hard frost when ground begins to freeze.
Protect trunks of young, thin-barked trees, such as ash, maples, and lindens, from winter sun scald by wrapping trunks with a commercial tree wrap.
Place a cylinder of hardware cloth, chicken wire, or fencing around plants to provide a good defense against rabbits, mice, and deer.
Spray evergreens, especially broadleafs (rhododendrons) with anti-transpirant to prevent winter burn.
Protect multi-stemmed evergreens, such as arborvitae, junipers, and yews, from winter storm damage by tying trunks together with old nylons or cotton twine.
Evaluate last year's garden and decide what changes need to be made. Draw garden plans on paper.
By February, order seeds and garden plants for spring planting.
