Once damage is done it is better to wait until spring before attempting any remedial measures.

Early fall freezes, late spring freezes and severe freezes during winter months often press plant tissues beyond their limits=FROST DAMAGE. Usually a plant can handle freezing weather when prepared for it, a process referred to as "Winter Hardiness" or "Hardening Off".

Symptoms are wilting; complete blackening or browning of leaves, twigs, flower buds, etc; death of tissues.

Once damage is done, it is better to wait until spring before attempting any remedial measures. It is still quite possible that a damaged plant has wood that has not been damaged too deeply and may recover in the spring. Pruning can stimulate new growth that is tender and vulnerable. Avoid fertilizing with a high nitrogen or quick release nitrogen. Deep root feeding can be done safely at any time of the year since its nitrogen is released over the period of a whole year.

  • Water thoroughly if the soil is dry. Water holds heat and freezes more slowly than dry soil.
  • Mulch heavily with bark, sawdust, shavings, etc.
  • Shelter the plant with cardboard, evergreen boughs, burlap, plastic, etc.
  • Move plants in containers under shelter. They are much more vulnerable than a plant in the ground.
  • Spray anti-transpirants. Example=Wiltpruf(TM) An anti-transpirant puts a protective waxy coating on leaves and have been advertised to protect rhodys from the frost damage.
  • Wait until spring for pruning, removal.


Although it is the broadleaf evergreens that are most liable to damage, there are other deciduos and coniferous plants that may also suffer damage because of a lack of genetic hardiness to extreme low temperatures.

Other cold temperature damage can include bark cracks on the south or west sides of the trunk and broken branches from heavy snows.
