Fruit trees — like apples, peaches, plums, pears, cherries and apricots — can all be damaged by temperatures lower than 31 degrees Fahrenheit.
How cold is too cold for trees?
At what temperatures do trees freeze? When temperatures are between 20 and 30 degrees Fahrenheit, most trees freeze. Because each tree is different, the exact temperature varies based on species, location and even the height of a tree.
What is the most cold hardy plum tree?
Cold Hardy Plum Trees
- Alderman – this plum variety is fairly cold tolerant.
- Blue Damson – this self-pollinating plum variety is fairly cold tolerant.
- Stanley – this self-pollinating plum variety is fairly cold tolerant.
- Superior – this plum variety is very cold tolerant.
At what temperature does fruit freeze?
Freeze damage to deciduous fruit crops can occur when temperatures dip below 31 degrees F.
Will plants freeze if the wind chill is below freezing?
If there is wind, it will pull the heat away from our body faster so it will feel colder. Since plants do not generate their own heat, wind chill does not affect them.
Will wind keep plants from freezing?
Wind also influences frost. If the air is still and windless, the coldest air settles to the ground. The temperature at plant level may be freezing, even though at eye level it isn’t. A gentle breeze, however, will prevent the cold air from settling and keep temperatures higher, protecting your plants.
Can plum trees survive winter?
The Plum Tree Chill Season
A plum tree can withstand cold ground temperatures for only so long, but it needs the chill hours to enable the tree to grow and produce fruit. Each variety of plum differs in its chill hour needs, which is when the ground is below 45 degrees Fahrenheit, but no lower than 32F.
Do you need 2 plum trees to pollinate?
Some plums are self-fertile; they will produce fruit without being pollinized by another variety. Others require cross-pollination with another plum in order to produce fruit reliably. Asian (Japanese) plums and European ones do not cross-pollinate and are listed separately.
Do you need two plum trees to get plums?
Most plum trees are not self-pollinating, so you will need to plant at least two plum trees to bear fruit. When planting a plum tree, it is important to make sure that the variety you choose will grow well in your climate. European, Japanese, and Damson plum varieties are available depending on your location.
How do you protect a plum tree from frost?
To protect smaller trees, put stakes in the ground around the tree and drape it with a sheet, burlap, fruit tree frost blanket, plastic, or other cloth during the day before the freeze. Make sure the cover goes all the way to the ground. A cover is used to hold heat around the tree.
Should I cover my fruit trees?
Covering up fruit trees and bushes can help to keep the blossoms just warm enough to make it through. Clearly, large trees cannot be covered up. On the plus side, flowers higher up on the tree may remain warm enough and go on to produce fruits even if the blooms on the lower branches get zapped.
Can plum blossoms survive frost?
Temperatures as low as 28 degrees are expected overnight in the region, with the potential for colder or milder actual lows dependent upon your location. Temperatures below 30 at this point in the season could damage the blossoms and nascent fruit of apples, pears, peaches, plums, blueberries and strawberries.
Will a covered porch protect plants from frost?
Moving plants indoors is the best protection. A covered porch usually provides protection from light frost, but the garage or sun room is better for freezing temperatures. A couple days in darkness won’t hurt the plant. Or move them out during the day and back in at night, if cold temperatures persist.
Should I cover my plants at 32 degrees?
When Should You Cover Plants? Cover your plants at night and remove them during the day when the temperatures rise above 32 degrees F, so that the soil can warm up again. Some outdoor plants won’t survive the harsh conditions of winter, bring them inside and use these tips for caring for them through winter.
At what temperature should you cover your plants at night?
Cover Plants – Protect plants from all but the hardest freeze (28°F for five hours) by covering them with sheets, towels, blankets, cardboard or a tarp. You can also invert baskets, coolers or any container with a solid bottom over plants. Cover plants before dark to trap warmer air.
Should I water my plants before a freeze?
Drought-stressed plants are more susceptible to cold damage, so watering plants a few days in advance of a cold snap is beneficial. Watering just before the freeze can help too by creating warmth, and the water loses its heat slowly over the hours into the colder temperatures.
Will bed sheets protect plants from frost?
Fabric coverings will prevent the freezing air from coming into direct contact with the moisture on the plant while also capturing the heat that is radiating from the ground. Bed sheets or comforters work best for covering large plants and shrubs.
What plants should I cover in a freeze?
Peppers, tomatoes, eggplants, and basil are a few plants that if protected from a freeze may continue to produce and grow. Other tender plants will need to be replanted in the spring.
Do I need to cover fruit trees in winter?
Protect Potted Trees. While it is important to winterize fruit trees that are planted directly in the ground, it’s absolutely critical to protect those that are planted in pots.

How do you protect fruit trees from freezing?
Protection From Frost
Use a cloth or burlap to cover the tree and trap in warm air. Be sure to completely cover the tree and extend fully down to the ground to provide adequate protection. You also don’t want your material sticking to blooms, this could cause even more damage.
