Evergreens are still susceptible to drought and wind damage through the winter months when wind is high and precipitation can be low. Trying to protect them from winter-kill/injury is very difficult to completely prevent. We recommend a couple things to help protect from the cold-drying winter winds:
1) Apply a coat of anti-transpirant to the leaves/needles during mid to late fall. Read instructions for specific application requirements.
2) Where possible give added protection to the shrub by insulation. (Ex. cover the base of roses with excess mulch to be removed in spring)
3) Adding burlap around trunks of trees that may possibly frost crack, will offer good protection going through the winter.
4) If a few warm days arrive in winter and it is above freezing – water your plants, particularly those 1 year old or less.
