There Is a Freeze Warning & I Just Planted Grapevine Plants: Do I Need to Cover Them?

Frost Protection

• Protect young grapevines from heavy freezes, which can cause trunk damage or kill the plant outright. Heap straw mulch or soil around the base of the plant and cover the plant with plastic, floating row covers or a sheet. Remove the mulch and covers as soon as the weather warms.

Plant Type

• A young grapevine's ability to withstand cold temperatures depends in part on the type of plant. Bare root grapevines are planted in early spring when the plant is still dormant. Successfully transplanting them can be difficult, but they are very cold hardy until they begin producing leaves. Potted plants are generally more tender because they have usually spent time in a greenhouse and are actively growing.

Variety

• When determining the need for frost protection, consider the variety as well. American-hybrid grape varieties, such as Concord, Niagara and Fredonia, are hardy, vigorous plants that tolerate cold conditions well. Muscadine grapes and European grapes are very tender and grow best in mild southern climates.

Site Selection

• When planting grapes, choose the location carefully to minimize the risk of frost damage. Plant grapes on a sunny slope, preferably with a south or southwestern orientation. Nearby buildings and trees can offer protection from the wind. Plant grape vines north and south, rather than east and west if possible, for better sun exposure.
