The weight of snow or ice can split the canopy of an arborvitae (Thuja). Recovery may occur depending on the extent of the damage. |
|
 |
To prevent snow or ice from splitting the canopy of an arborvitae (Thuja) tie the crown together with nylon stockings when a storm is predicted and remove before spring. |

Evergreens, in this case white pine (Pinus strobus) often suffer most from ice storms because they have more leaf surfaces to which the ice can cling. |

This breathable fabric draped around a pot shows one method of protecting tender plants when frost is predicted |
|
 |
Floating row covers are used to protect these vegetables from a late frost; note that material used is light weight and airy |
|
 |
When protecting plants from a frost, it is important to use a light weight material, such as, floating row covers, but the material must be secured to the ground to prevent it from blowing away and to take advantage of soil warmth. |
|
 |
Row covers are excellent for protecting heavy pots from frost. Unfortunately, to be effective the cover needs to be secured to the ground, not to the pot. |

Heavy snowfall caused a row of arborvitae (Thuja occidentalis 'Klmeighteen' PATRIOT) to double over, nearly touching the ground. |
|
 |
After the snow melted the row of arborvitae (Thuja occidentalis) are still split apart. |
|
 |
To repair arborvitae (Thuja) split apart by snow or ice, they must be tied back together until they mend. This could be done in early winter before damage occurs and removed again in spring. |
|
 |
Arborvitae (Thuja) split apart by snow or ice can be tied back together until they mend at which point the ties should be removed. |
