Propagation Of Christmas Trees
The Propagation of Christmas trees is the series of procedures carried out to grow new Christmas trees. Many different species of evergreen trees are used for Christmas trees. The most common of these species are classified in the four genera: pines, spruces, firs, and cypress. Christmas trees can be grown from seed or from root cuttings. Varieties of traditional Christmas trees There are many different species of evergreen trees that are used for Christmas trees. The most common of these species are classified in one of four genera: pines (genus Pinus), spruces (genus Picea), firs (genus Abies), and cypress (genus Cupressa). In addition to these, the Douglas fir (Pseudotsuga Menziesii) is also commonly used as a Christmas tree, but it is not a true fir. The varieties of trees that a nursery chooses to propagate is dependent upon what type of farm is buying the reproduced plant, the climate of the nursery, the climate of the tree farm where the trees are to be grown, and the pre ...

Fir Seedlings
Firs (''Abies'') are a genus of 48–56 species of evergreen coniferous trees in the family Pinaceae. They are found on mountains throughout much of North and Central America, Europe, Asia, and North Africa. The genus is most closely related to '' Cedrus'' (cedar). The genus name is derived from the Latin "to rise" in reference to the height of its species. The common English name originates with the Old Norse, fyri, or the Old Danish, fyr. They are large trees, reaching heights of tall with trunk diameters of when mature. Firs can be distinguished from other members of the pine family by the way in which their needle-like leaves are attached singly to the branches with a base resembling a suction cup, and by their cones, which, like those of true cedars, stand upright on the branches like candles and disintegrate at maturity. Identification of the different species is based on the size and arrangement of the leaves, the size and shape of the cones, and whether the bract ...

Frasier Fir
The Fraser fir (''Abies fraseri'') is a species of fir native to the Appalachian Mountains of the Southeastern United States. ''Abies fraseri'' is closely related to ''Abies balsamea'' (balsam fir), of which it has occasionally been treated as a subspecies (as ''A. balsamea'' subsp. ''fraseri'' (Pursh) E.Murray) or a variety (as ''A. balsamea'' var. ''fraseri'' (Pursh) Spach).Farjon, A. (1990). ''Pinaceae. Drawings and Descriptions of the Genera''.

Pinus Radiata
''Pinus radiata'' (syn. ''Pinus insignis''), the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico ( Guadalupe Island and Cedros island). It is an evergreen conifer in the family Pinaceae. ''P. radiata'' is a versatile, fast-growing, medium-density softwood, suitable for a wide range of uses. Its silviculture reflects a century of research, observation and practice. It is often considered a model for growers of other plantation species. It is the most widely planted pine in the world, valued for rapid growth and desirable lumber and pulp qualities. Although ''P. radiata'' is extensively cultivated as a plantation timber in many temperate parts of the world, it faces serious threats in its natural range, due to the introduction of pine pitch canker ('' Fusarium circinatum''). Description ''P. radiata'' is a coniferous evergreen tree growing to tall in the wild, but up to in cultivation in opti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Climate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the A ...

Mason–Dixon Line
The Mason–Dixon line, also called the Mason and Dixon line or Mason's and Dixon's line, is a demarcation line separating four U.S. states, forming part of the borders of Pennsylvania, Maryland, Delaware, and West Virginia (part of Virginia until 1863). It was surveyed between 1763 and 1767 by Charles Mason and Jeremiah Dixon as part of the resolution of a border dispute involving Maryland, Pennsylvania, and Delaware in colonial America. The dispute had its origins almost a century earlier in the somewhat confusing proprietary grants by King Charles I to Lord Baltimore (Maryland) and by King Charles II to William Penn (Pennsylvania and Delaware). The largest, east-west portion of the Mason–Dixon line along the southern Pennsylvania border later became known, informally, as the boundary between the Southern slave states and Northern free states. This usage came to prominence during the debate around the Missouri Compromise of 1820, when drawing boundaries betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Nursery
A nursery is a place where plants are propagated and grown to a desired size. Mostly the plants concerned are for gardening, forestry or conservation biology, rather than agriculture. They include retail nurseries, which sell to the general public, wholesale nurseries, which sell only to businesses such as other nurseries and to commercial gardeners, and private nurseries, which supply the needs of institutions or private estates. Some will also work in plant breeding. A nurseryman is a person who owns or works in a nursery. Some nurseries specialize in certain areas, which may include: propagation and the selling of small or bare root plants to other nurseries, growing out plant materials to a saleable size, or retail sales. Nurseries may also specialize in one type of plant: e.g., groundcovers, shade plants, or rock garden plants. Some produce bulk stock, whether seedlings or grafted, of particular varieties for purposes such as fruit trees for orchards, or timber ...

Wholesalers
Wholesaling or distributing is the sale of goods or merchandise to retailers; to industrial, commercial, institutional or other professional business users; or to other wholesalers (wholesale businesses) and related subordinated services. In general, it is the sale of goods in bulk to anyone, either a person or an organization, other than the end consumer of that merchandise. Wholesaling is buying goods in bulk quantity, usually directly from the manufacture or source, at a discounted rate. The retailer then sells the goods to the end consumer at a higher price making a profit. According to the United Nations Statistics Division, ''wholesale'' is the resale of new and used goods to retailers, to industrial, commercial, institutional or professional users, or to other wholesalers, or involves acting as an agent or broker in buying merchandise for, or selling merchandise to, such persons or companies. Wholesalers frequently physically assemble, sort, and grade goods in la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Farm
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Red Cedar
''Juniperus virginiana'', also known as red cedar, eastern red cedar, Virginian juniper, eastern juniper, red juniper, and other local names, is a species of juniper native to eastern North America from southeastern Canada to the Gulf of Mexico and east of the Great Plains. Further west it is replaced by the related ''Juniperus scopulorum'' (Rocky Mountain juniper) and to the southwest by '' Juniperus ashei'' (Ashe juniper).Farjon, A. (2005). ''Monograph of Cupressaceae and Sciadopitys''. Royal Botanic Gardens, Kew. Adams, R. P. (2004). ''Junipers of the World''. Trafford. Description ''Juniperus virginiana'' is a dense slow-growing coniferous evergreen tree that may never become more than a bush on poor soil, but is ordinarily from tall, with a short trunk in diameter, rarely to in height and in diameter. The oldest tree reported, from West Virginia, was 940 years old. The bark is reddish-brown, fibrous, and peels off in narrow strips. The leaves are of two types; sharp ...

Leyland Cypress
The Leyland cypress, ''Cupressus'' × ''leylandii'', often referred to simply as leylandii, is a fast-growing coniferous evergreen tree much used in horticulture, primarily for hedges and screens. Even on sites of relatively poor culture, plants have been known to grow to heights of in 16 years. Their rapid, thick growth means they are sometimes used to achieve privacy, but such use can result in disputes with neighbours whose own property becomes overshadowed. The tree is a hybrid of Monterey cypress ('' Cupressus macrocarpa'') and Nootka cypress ('' Cupressus nootkatensis''). It is almost always sterile, and is propagated mainly by cuttings. History In 1845, the Leighton Hall, Powys estate was purchased by the Liverpool banker Christopher Leyland. In 1847, he gave it to his nephew John Naylor (1813–1889). Naylor commissioned Edward Kemp to lay out the gardens, which included redwoods, monkey puzzle trees and two North American species of conifers in close proximity to ...

Arizona Cypress
''Cupressus arizonica'', the Arizona cypress, is a North American species of tree in the cypress family Cupressaceae, native to the southwestern United States and Mexico. Populations may be scattered rather than in large, dense stands. Description ''Cupressus arizonica'' is a coniferous evergreen tree with a conic to ovoid-conic crown. It grows to heights of , and its trunk diameter reaches . The foliage grows in dense sprays, varying from dull gray-green to bright glaucous blue-green. The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots. The seed cones are globose to oblong, 15–33 mm long, with 6 or 8 (rarely 4 or 10) scales, green at first, maturing gray or gray-brown about 20–24 months after pollination. The cones remain closed for many years, only opening after the bearing branch is killed (in a wildfire or otherwise), allowing the seeds to colonize the bare ground exposed by the fire. The male cones are 3–5 mm long, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Fir
''Abies concolor'', the white fir, is a coniferous tree in the pine family Pinaceae. This tree is native to the mountains of western North America, including the Cascade Range and southern Rocky Mountains, and into the isolated mountain ranges of southern Arizona, New Mexico, and Northern Mexico. It naturally occurs at elevations between . It is popular as an ornamental landscaping tree and as a Christmas tree.
