Parasiticides which are effective against the larvae include macrolytic lactones, such as ivermectin and moxidectin, and organophosphates, such as metrifonate (also known as trichlorphon) and dichlorvos. The best time to deworm horses against Gasterophilus intestinalis is after the first hard frost. This hard frost will kill the females so no new eggs can be laid on the horse that can be ingested. Meaning that the dewormer is acting on the larva attached to the stomach and will also decrease the amount of larva shed in the feces in the spring.

Acis trichophylla is a species of flowering plant in the family Amaryllidaceae, native to Portugal, Spain and Morocco. It has very narrow leaves. The flowers are produced in late winter or early spring and are usually white, but sometimes pink-tinged or all pink. The species is cultivated as an ornamental bulb, but requires protection from hard frost.

Burnell, pp. 110-111 Both crews suffered variously during the buildup to the race. A hard frost which persisted late into the season hindered training, forcing both crews to move to Bourne End and more open water. Both crews were then struck by influenza, Cambridge three weeks before the race and Oxford the week of the race itself.

The early settlers called it the frost grape, as it was best when picked after the first hard frost. With the influx of settlers in the 1840s and '50s, grape growing was tried along with all other horticultural pursuits. Varieties developed on the eastern seaboard such as the Concord were somewhat successful. The fruit was commercially used for fresh fruits or preserves.

Cistuses are suitable for sunny gardens with a nearly frost- free Mediterranean climate. The hardiest of the species is C. laurifolius, which survived the hard frost at Royal Botanical Gardens at Kew in 1895 that eliminated all the cistuses save this and two white-flowered natural hybrids, C. × corbariensis, already grown by John Tradescant the Elder, and C. × loretii, a 19th-century introduction.

In winter, from the end of November to the beginning of March, precipitation falls partly in the form of snow. The snow cover varies considerably. The thinnest snow cover is found in the eastern region of the Great Plain (with the annual average being ). Often winter corn remains open to the elements, when farmers do not expect any hard frost.

She often suspends the egg sac right on her web, near the center where she spends most of her time. Each spider produces from one to four sacs with perhaps over a thousand eggs inside each. She guards the eggs against predation as long as she is able. However, as the weather cools, she becomes more frail, and dies around the time of the first hard frost.

In cultivation, pineapple sage grows to tall, with the roots extending underground to form a large clump. The pale yellow-green leaves are veined, and covered with fine hairs. Six to twelve scarlet flowers grow in whorls, with a long inflorescence that blooms gradually and over a prolonged period of time. With a hard frost, the plant will die down to the ground and grow back the following spring.

Pseudoperonospora cubensis is an obligate parasite or biotroph, meaning that it requires live host tissue in order to survive and reproduce. Because of this characteristic, the pathogen must overwinter in an area that does not experience a hard frost, such as southern Florida, and where wild or cultivated cucurbits are present. The spores are dispersed via wind to neighboring plants and fields and often over long distances. Symptoms appear 4 to 12 days after infection.

Salvia patens is frequently treated as an annual by gardeners due to its sensitivity to hard frost, with bedding plants often put out in spring. Varieties have been developed with colors ranging from white to lilac to various shades of blue. Seeds from the Netherlands have been available since the 1990s for rich colored and large flowered varieties. The species and its cultivar 'Cambridge blue' have gained the Royal Horticultural Society's Award of Garden Merit.

In Finnish, the month is called helmikuu, meaning "month of the pearl"; when snow melts on tree branches, it forms droplets, and as these freeze again, they are like pearls of ice. In Polish and Ukrainian, respectively, the month is called luty or лютий ("lyutiy"), meaning the month of ice or hard frost. In Macedonian the month is sechko (сечко), meaning month of cutting (wood). In Czech, it is called únor, meaning month of submerging (of river ice).

Ailuromancy or aeluromancy (from Greek αἴλουρος aílouros meaning "cat"), also known as felidomancy, is a form of theriomancy. It is divination using cats' movements or jumps to predict future events, especially the weather. One of the most common methods of ailuromancy utilizes the movements and behaviours of a cat to predict upcoming weather patterns. For example, if the cat turns its tail to a fire or any substituting heat source, it foretells a possible change in weather, particularly the coming of heavy rain or hard frost.

In 1977 Frost appeared in a radio play called Three Days of Frost, in which Frost was played by Leslie Sands, a friend of Wingfield's. The books were first published in the United Kingdom in early 1989, and in 1992 Frost first appeared on television in A Touch of Frost, played by David Jason. Wingfield was never enthusiastic about the TV adaptation of his detective, once saying he had nothing against David Jason but "he just isn't my Frost". Hard Frost was published in 1995, followed by Winter Frost in 1999.

Pinus canariensis, the Canary Island pine, is a species of gymnosperm in the conifer family Pinaceae. It is a large, evergreen tree native and endemic to the outer Canary Islands (Gran Canaria, Tenerife, El Hierro and La Palma) in the Atlantic Ocean. It is a subtropical pine and does not tolerate low temperatures or hard frost, surviving temperatures down to about −6 to −10 °C. Within its natural area, it grows under extremely variable rainfall regimes, from less than to several thousands, mostly due to differences in mist- capturing by the foliage.

Drought. Frost and cold are major causes of crop damage to tender plants, although hardy plants can also suffer if new growth is exposed to a hard frost following a period of warm weather. Symptoms will often appear overnight, affecting many types of plants. Leaves and stems may turn black, and buds and flowers may be discoloured, and frosted blooms may not produce fruit. Many annual plants, or plants grown in frost free areas, can suffer from damage when the air temperature drops below 40 degrees Fahrenheit (4 degrees Celsius).

This species was first described as Ardea stellaris botaurus as early as the 1660s by the ornithologist Thomas Browne The Miscellaneous writings of Sir Thomas Browne edited by Geoffrey Keynes pub. Cambridge University Press 1931 where Browne writes, 'The Ardea stellaris botaurus, or bitour, is also common & esteemed the better dish.In the belly of one I found a frog in a hard frost at Christmas. Another I kept in a garden 2 yeares, feeding it with fish, mice, & frogges; in defect of whereof, making a scrape for sparrowes & small birds, the bitour made shift to maintaine herself upon them'.

Parts of east-central Florida near Orlando have an ecotype with similar-looking leaves to the coastal plain variant of the Carolinas; it flowers much earlier (usually in March, although flowering can begin in late January), with a smaller yellower bloom than other types. This east central Florida ecotype/Peninsular allozyme group seems to have the best ability to tolerate very wet conditions, where it may grow short pencil-like root structures (pneumatophores) similar to those produced by other swamp trees in warm climates. Superior resistance to drought, pests and wind is also noted. Some individuals retain their leaves all year unless a hard frost strikes.

The blue jacaranda has been cultivated in almost every part of the world where there is no risk of frost; established trees, however, tolerate brief spells of temperatures down to around . In the US, east of Los Angeles, where winter temperatures can dip to for several-hour periods, the mature tree survives with little or no visible damage. Even when young trees are damaged by a hard frost and suffer die back, they will often rebound from the roots and grow in a shrub-like, multi-stemmed form. However, flowering and growth will be stunted if the jacaranda is grown directly on the California coast, where a lack of heat combined with cool ocean winds discourages flowering.

Studies show that the intense flavor of the fruits of this plant come from at least 31 different aromatic flavor compounds V. deliciosum, like other plants that live alpine communities, have adapted to survive in growing seasons as short as three or four months. From late fall to spring, the plants rely on snow cover to insulate them from temperatures more than several degrees below freezing. Blossoms can become damaged and summer growth can be stunted if the plants experience a hard frost below negative four degrees celsius if unprotected by snow. However, the plants do require a vernalization period of freezing temperatures for at least a few months for flowering to occur.

In the UK, loads may be hand examined at the factory gate before being accepted. In the US, the fall harvest begins with the first hard frost, which arrests photosynthesis and the further growth of the root. Depending on the local climate, it may be carried out over the course of a few weeks or be prolonged throughout the winter months. The harvest and processing of the beet is referred to as "the campaign", reflecting the organization required to deliver the crop at a steady rate to processing factories that run 24 hours a day for the duration of the harvest and processing (for the UK, the campaign lasts about five months).

However, since the color often develops very late in autumn, the leaves may be killed by a hard frost before full color can develop. Callery pears are remarkably resistant to disease or fireblight though some cultivars such as 'Bradford' are particularly susceptible to storm damage and are regularly disfigured or even killed by strong winds, ice storms, heavy snow, or limb loss due to their naturally rapid growth rate. The species is named after the Italian-French sinologue Joseph-Marie Callery (1810–1862) who sent specimens of the tree to Europe from China.Reimer, F.C., "A promising new pear stock," The Monthly Bulletin, California State Commission of Horticulture, 5:5 (May 1916), p. 167.

However, it will exhibit epiphytic characteristics if given the opportunity to attach itself to a nearby supporting tree and climb upon it. The trunk of this plant can send down many strong aerial roots that not only give support to the overall plant mass, but also serve to absorb water and nutrients from the soil. This plant is greatly known for its ease in covering a land mass, and typically spread out its tree-like trunk from anywhere between eight and ten feet. Alternatively, if grown in cooler climates with at least some freezing winter weather, its entire aboveground structures will die back completely at a hard frost and then sprout back from the roots the following spring.

However he was less fortunate against Faidherbe at Pont Noyelles and Bapaume. In January 1871 he commanded the newly formed Army of the South, which he led, in spite of hard frost, through the Côte-d'Or and over the plateau of Langres, cut off Bourbaki's Army of the East with 80,000 men, and, after the action of Pontarlier, compelled it to cross the Swiss frontier, where it was disarmed. His immediate reward was the Grand Cross of the Iron Cross, and at the conclusion of peace he was made a member of the Order of the Black Eagle. When the Southern Army was disbanded Manteuffel commanded the Second Army and, from June 1871 until 1873, the army of occupation left in France, showing great tact in a difficult position.

Some of the smaller islands of Shetland were particularly hard hit – Fair Isle had previously had between ten and twelve families, but is said to have lost two thirds of its population in the 1700 outbreak, leaving too few to effectively manage their fishing boats; in Fetlar smallpox killed over 90 islanders of whom "most were married people". Smallpox would continue to strike Shetland every 20 years, with epidemics occurring in 1700, 1720, 1740 and 1760. The 1720 epidemic hit Foula particularly hard, where it is said "there were scarcely people left to bury the dead", whereas in Fetlar a certain amount of resistance is thought to have built up, as most of the 80 who died were under the age of 20. The 1740 epidemic required the extension of the Lerwick cemetery by , while in Fetlar a further 120 people died – this was exacerbated by a hard frost lasting over a month that prevented the dead from being buried.
