Late spring frosts can damage and even kill peach trees. There’s nothing more painful for a gardener than to watch years of time and money shrivel under frosty winter temperatures. Peach trees, in particular, require a specific amount of winter temperatures before coming out of dormancy and producing fruit. If planted in the wrong environment, a tree may come out of dormancy too early and lose its fruit to an unexpected frost. Always be sure to protect your peach trees throughout the winter season.
Cover the trunk and branches of your peach trees with fleece blankets or sheets. Only use materials that do not weigh down branches or cause limbs to sag. Depending on the duration of below freezing temperatures, the cloth may freeze to the bark and should be removed with care.
Wrap the branches in Christmas lights and leave on throughout the night. This safely brings heat close to branches and creates a lovely garden display.
Fully cover the tree with a large plastic tarp. This will trap ground heat as well as keep moisture off the skin of the tree.
Place a 150 watt bulb under the tarp to provide a direct heat source. Be sure the bulb does not directly touch the plastic or it may cause it to melt.
Spread high quality mulch around the base of the tree, leaving a 12-inch radius around the trunk. This will help insulate the roots without choking the tree.
