Apples are a common sight across all climates, but there is a myth that apples freeze on the tree in cold weather. This myth arises from the fact that apples do contain an abundance of water, which typically freezes in cold temperatures. However, the myth does not consider the many other factors that affect whether apples will freeze on the tree.
In the first instance, it is important to consider the extent of the cold weather. Standard frost temperatures in most regions of the world, around minus two or two to three degrees Celsius, are typically not enough to freeze an entire apple on the tree. The worst frosts can get to around minus fifteen to twenty degrees Celsius, and will freeze apples completely on the tree.
The size and maturity of the apple is another important factor. Smaller apples with thin skins are more prone to freezing than larger, thicker skinned apples. Similarly, apples that are still immature and not fully ripe will more readily freeze than more mature apples.
The amount of sunshine is also a major influencing factor on whether apples will freeze on the tree. In sunny weather, the apple can warm up enough during the day to remain liquid and free flowing even in the evening in less favourable temperatures. On overcast days, the apple will not warm up as much, and is much more vulnerable to frost.
The type of apple grown in a certain region also plays a factor. Some apples, such as crab and old fashioned varieties, retain more starch and other characteristics that prevent freezing. On the other hand, modern apples with higher levels of sugar and soft, delicate skins tend to be more likely to freeze than their traditional counterparts.
Finally, the location of the tree is another major factor: trees planted in sheltered areas such as in valleys or among trees are more likely to remain safe from frost than those exposed to cold winds and icy temperatures. The same applies to gardens or orchards where the trees are not properly cared for or have been neglected.
Temperature:
Temperature is one of the key factors in determining whether apples freeze on the tree. Generally, a temperature of -15C or below is needed to freeze an entire apple on the tree, although it is possible at lower temperatures depending on the size, maturity, variety and location of the tree. Standard frost temperatures are usually not enough to freeze an entire apple on the tree.
Size & Maturity:
Smaller apples with thin skins will more readily freeze than larger, thicker skinned apples. Similarly, apples that are still relatively immature and not fully ripe will more readily freeze than more mature apples. Therefore, size and maturity play an important role in determining whether an apple will freeze on the tree.
Sunshine Levels:
The amount of sunshine also has a major influence on apple freezing. In sunny weather, apples can warm up enough during the day to remain liquid and free flowing even in the evening in less favorable temperatures. However, on overcast days, relatively colder temperatures are more likely to cause apples to freeze.
Variety:
The type of apple grown in a certain area also affects the likelihood of freezing. Apples that are high in starch, such as crab and old-fashioned varieties, are usually more resistant to freezing than modern apples with higher levels of sugar and soft, delicate skins. Therefore, selecting the right variety of apples is important in avoiding apples freezing on the tree.
Location:
The location of the tree can also determine the likelihood of freezing. Trees that are planted in valleys or among other trees are more likely to remain safe from frost than those unshielded and exposed to cold winds. Similarly, gardens or orchards where the trees have been neglected or lack adequate care are more likely to experience freezing.
Preventive Measures:
In order to prevent apples from freezing on the tree, it is important to take the necessary measures to ensure that temperatures are kept at or above -15C. This includes planting trees in sheltered areas, properly caring for gardens and orchards, and selecting apple varieties that are less likely to freeze in cold weather. Additionally, regularly monitoring and checking frost temperatures is crucial to minimize the risk of apple freezing.
Summary:
Apples can freeze on the tree in certain extreme conditions, such as when temperatures reach -15C or colder. The size, maturity and variety of the apple, as well as sunshine levels and the location of the tree can all influence apple freezing. In order to prevent freezing, it is important to take preventive measures, such as planting trees in sheltered areas, monitoring frost temperatures, and selecting appropriate varieties of apples.
