Apple trees are incredibly hardy and can stand much colder weather than you will ever see in the UK. However, their flowers can be damaged in freezing weather making pollination impossible and so preventing them from cropping. So the lists below contains some varieties of apple tree that are better suited to cold spots. By the way, the actual damage from frost is caused if frozen plant tissues defrost too quickly.

5 Best Fruit Trees For Cold Climates

As the days become shorter and cooler in fall, deciduous plants stop growing, store energy, lose their leaves and enter a state of dormancy which protects them from the freezing temperatures of winter. Additional factors that affect fruit set include age of tree, nutrition, availability of compatible pollen and weather during bloom.

Fruit tree chilling requirements can vary widely from one variety to another. Some highly productive varieties, however, will produce well over a wide range of climates and chilling. Subsequent hard frosts could cause crop failure year after year.

A disadvantage of heavier crops is they require more thinning for best fruit quality and size. Home fruit growers often prefer moderate crops and less thinning work; commercial growers need maximum crops. Heavy crops can also lead to alternate bearing heavy crops alternating with very light crops. So, how do we measure chilling? Depending on the method used, fruit tree chilling is expressed either in hours of defined cold temperatures or in other calculated units based on the occurrence of various temperatures.

Using this model, if a fruit tree were observed to bloom and fruit satisfactorily after winters of or more chill hours, but inconsistently after winters of chill hours and less, the variety would be regarded as having a chilling requirement of hours. In terms of winter cold adaptation, this approach works reasonably well for matching most fruit varieties with suitable climates. It tends to be less reliable, however, for subtropical climates and varieties with very low chilling requirements - and is not especially useful for the coldest fruit tree climates.

To date, all models tend to give significantly different results for different climates. Since hours below freezing are typically accompanied by hours above freezing at good chilling temperatures, the correlation is the same: more cold means more chilling, leading to a strong bloom and bumper crops of stone fruits and almonds. Local fruit tree chilling information and data are available from agricultural universities and extension offices, area retail nurseries and via internet search.

As noted above, it is very difficult to measure chilling precisely; stated fruit tree chilling requirements are necessarily approximations or estimates. Regardless of the actual chilling algorithm built into a particular variety, the DWN estimated chilling requirement represents the relative amount of winter cold that variety has been observed or is thought to require, expressed in chill hours.

The chilling requirement estimate for a new fruit variety is usually based on its behavior in the climate of origin and on parentage, if known. In any case, chilling requirement approximations for a deciduous fruit variety can be improved over a number of years by performance reports which follow dormant periods of varying temperature histories.

Much of California is blessed with a wonderful deciduous fruit growing climate: plenty of chilling, no particular spring frost problem and a long, hot, dry growing season. In such areas it is possible to grow almost any kind of deciduous fruit including varieties with chilling requirements anywhere from to or more hours.

For coastal southern California, low-chill varieties are considered to be those requiring less than hours. In southern California and the lower deserts of Arizona winters can be short, often lasting less than two months, so it is essential to choose varieties that are low chill.

Researchers suggest also that some varieties in the absence of cold are better able than others to "switch" to a heat requirement for triggering bloom and setting a crop. Many "northern" apple varieties can set crops satisfactory for home orchards with far less than the recommended winter chilling but may not develop best fruit quality and color if summer and fall nights are warm.

Varieties adapted to colder climates usually, but not always, have chilling requirements of , or more hours. In the coldest fruit tree climates, though, growers are little concerned with chilling requirements; almost all varieties receive their chilling requirement early in winter.

In these climates the need is for later-blooming, frost hardy varieties. Some of the most cold hardy fruit varieties, in fact, appear to have very low minimum chilling requirements; their cold hardiness derives from a higher heat requirement for ending dormancy — once dormant they are not easily fooled by an early warm spell.

Note: In nursery catalogs, higher stated chilling requirements often mean, essentially, "adapted to colder climates" or "tested in a colder climate". Note also that bloom timing is not necessarily indicative of a variety's chilling requirement, as the variety's heat requirement for bloom also plays a role.

A fruit variety is proven for a climate or region by planting and growing it there; promising new varieties are planted by adventurous growers. Note that a deciduous fruit tree's best fruit bud formation and cropping performance can occur only when it is not over-watered, over-fertilized, nor under-pruned. When choosing fruit varieties to plant, area retail nurseries, agricultural universities, county cooperative extension offices and Master Gardener programs are good resources for local fruit growing information and ideas.

In fall, deciduous fruit trees lose their leaves and enter a dormant state in order to survive winter. Chilling requirements vary widely among varieties. Fruit varieties with chilling requirements much lower than received at the planting location may end dormancy and bloom too early, subjecting tree, bloom and fruit to freeze damage. Conversely, varieties with chilling requirements much higher than received will suffer delayed, weak leafing and blooming and will not fruit satisfactorily.

Such findings help explain the response of specific varieties to different climates, i. Published chilling requirements for a fruit variety can be the minimum chilling required to produce a satisfactory home garden crop up to a higher requirement for the consistent, maximum crop sought by commercial growers.

Note that many apple varieties can set fruit with far less chilling than recommended, color and quality depending on climate. Some cold hardy fruit varieties are widely adapted because they have a low or moderate chilling requirement as well as a cold hardiness deriving from a high heat requirement for ending dormancy.

Much of California has an ideal, virtually frost-free fruit growing climate where almost any kind of deciduous fruit can be grown, including varieties with chilling requirements anywhere from to or more hours. A variety is proven for a climate or region only by growing it there.

When choosing fruit varieties always refer to area retail nurseries, agricultural universities, county extension offices and master gardeners for local fruit growing information and ideas.

If you have the space, desire, and commitment to grow tree fruits consider these points before selecting your cultivars:. Most tree fruits suited for the mid-Atlantic region are botanically grouped into two categories: pome fruits and stone fruits. The pome fruits comprise apples Malus and pears Pyrus and share many cultural similarities and pest problems. Likewise, the stone fruits—peaches, plums, apricots, nectarines, and cherries Prunus —share cultural similarities and pests.

Another source of frost hardiness is the Ichang papeda, Citrus ichangensis, which can easily withstand °C. In contrast to Poncirus trifoliata, it also keeps.

Frost hardy citrus varieties

Gerard W. Powell, Former Extension Horticulturist. Citrus plants are very versatile around the home and may be used as individual specimens, hedges or container plants. Their natural beauty and ripe fruits make them attractive additions to the South Georgia home scene. Cold-hardy varieties that receive recommended care may grow successfully in the coastal and extreme southern areas of the state and to a lesser degree in more northern locations. Areas where citrus are best adapted within the state are shown in Figure 1. The most significant limiting factor to citrus culture in these areas is damage from severe winter temperature. The following brief history of citrus culture in the United States vividly illustrates the devastating effect of winter freezes.

Download Resource. Pruning and pest management — these two chores can be discouraging tasks for many home tree fruit growers. Is it possible to grow tree fruits with limited inputs? With proper tree selection and site preparation, the answer can be yes. The first and perhaps most important issue is site selection. Fruit trees will grow and produce best if planted on deep, well-drained sandy loams with good moisture and nutrient-holding capacity. In addition, full sunlight nearly all day long is essential. In addition, full sunlight promotes quick drying after rain events, reducing the risk of disease pressure.
