Perfect for gardens in temperate climates, hydrangeas need a winter dormancy that is punctuated with frost and subfreezing temperatures.However, if a hydrangea shrub is leafy or in bloom, frost will scald it and turn the plant tissue brown, and the petals and leaves will drop off.Untimely spring frosts can kill flower and leaf buds on shrubs, and reduce or prevent flowering later in spring and summer.rotect shrubs from a late frost by covering them with a cloth sheet or blanket when unseasonal cold is forecast.
