Pruning
Pruning is the selective removal of certain parts of a plant, such as branches, buds, or roots. It is practiced in horticulture (especially fruit tree pruning), arboriculture, and silviculture. The practice entails the targeted removal of diseased, damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants. In general, the smaller the branch that is cut, the easier it is for a woody plant to compartmentalize the wound and thus limit the potential for pathogen intrusion and decay. It is therefore preferable to make any necessary formative structural pruning cuts to young plants, rather than removing large, poorly placed branches from mature plants. Woody plants may undergo a process referred to as ''self-pruning'', where they will drop twigs or branches which are no longer producing more energy than they require. It is theorized that this process can also occur in response to lack of water, in order to reduce the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branch Collar
A branch collar is the "shoulder" between the branch and trunk of woody plants; the inflammation formed at the base of the branch is caused by annually overlapping Trunk (botany), trunk tissue. The shape of the branch collar is due to two separate growth patterns, initially the branch grows basipetally, followed by seasonal trunk growth which envelops the branch. Branch collars serve as a strong foundation to the branch, and its orientation and internal characteristics allow the branch to withstand stress from numerous directions. Functionally the branch collars also influence the Conductivity (electrolytic), conductivity of nutrients and growth patterns. The branch collar which provides a protective barrier to prevent infection and decay, can also be useful in diagnosing bacterial diseases. Proper pruning techniques should accommodate for the branch collar structure, as by damaging the tree it is likely to decay or become diseased. Definition In arboriculture, the "shoulder" ...

Fruit Tree Pruning
Fruit tree pruning is the cutting and removing of selected parts of a fruit tree. It spans a number of horticultural techniques. Pruning often means cutting branches back, sometimes removing smaller limbs entirely. It may also mean removal of young shoots, buds, and leaves. Established orchard practice of both organic and nonorganic types typically includes pruning. Pruning can control growth, remove dead or diseased wood, and stimulate the formation of flowers and fruit buds. It is widely stated that careful attention to pruning and training young trees improves their later productivity and longevity, and that good pruning and training can also prevent later injury from weak crotches or forks (where a tree trunk splits into two or more branches) that break from the weight of fruit, snow, or ice on the branches. Some sustainable agriculture or permaculture personalities, such as Sepp Holzer and Masanobu Fukuoka, advocate and practice no-pruning methods, which runs coun ...

Secateurs
Pruning shears, also called hand pruners (in American English) or secateurs (in British English), are a type of scissors used for plants. They are strong enough to prune hard branches of trees and shrubs, sometimes up to two centimetres thick. They are used in gardening, arboriculture, plant nursery works, farming, flower arranging, and nature conservation, where fine-scale habitat management is required. They are typically manually powered, although electric versions are available. Loppers are a larger, two-handed, long-handled version for branches thicker than pruning shears can cut. History Cutting plants as part of gardening dates to antiquity in both European and East Asian topiary, with specialized scissors used for Chinese penjing and its offshoots – Japanese bonsai and Vietnamese Hòn Non-Bộ – for over a thousand years. In modern Europe, scissors only used for gardening work have existed since the early 1800s, when the French aristocrat Antoine-François Bertr ...

Silviculture
Silviculture is the practice of controlling the growth, composition/structure, as well as quality of forests to meet values and needs, specifically timber production. The name comes from the Latin ('forest') and ('growing'). The study of forests and woods is termed ''silvology''. Silviculture also focuses on making sure that the treatment(s) of Stand level modelling, forest stands are used to conserve and improve their productivity. Generally, silviculture is the science and art of growing and cultivating forest crops based on a knowledge of silvics, the study of the life history and general characteristics of forest trees and stands, with reference to local/regional factors. The focus of silviculture is the control, establishment and management of forest stands. The distinction between forestry and silviculture is that silviculture is applied at the Stand level modelling, stand-level, while forestry is a broader concept. Adaptive management is common in silviculture, while fores ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arborist
An arborist, or (less commonly) arboriculturist, is a professional in the practice of arboriculture, which is the Plant cultivation, cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants in dendrology and horticulture. Arborists generally focus on the health and safety of individual plants and trees, rather than managing forests or harvesting wood (silviculture or forestry). An arborist's scope of work is therefore distinct from that of either a forester or a lumberjack, logger. Scope of work In order for arborists to work near power wires, either additional training is required or they need to be certified as a Qualified Line Clearance Arborist or Utility Arborist (there may be different terminology for various countries). There is a variety of minimum distances that must be kept from power wires depending on voltage, however the common distance for low voltage lines in urban settings is 10 feet (about 3 metres).

Loppers
Loppers are a type of scissors used for pruning twigs and small branches, like pruning shears with longer handles. They are a larger type of manual garden cutting tool, but not as long as pole pruners (averruncators in British English). Loppers are usually operated with two hands, and have handles typically between and long to give good leverage. Some have telescopic handles which can be extended to a length of , in order to increase leverage and to reach high branches on a tree. Loppers are mainly used for the pruning of tree branches with diameters less than . Some of the newer lopper designs have a gear system, a compound lever system, or a ratchet drive, which increases the force applied to the blades. Etymology The word ''wikt:lopper, lopper'' can be used in the singular or the plural, with precisely the same meaning. The plural form, most common in speech but less so in print, is a plurale tantum, and seems to be on the model of a ''pair of scissors''. The name of the to ...

Garden Tool
A garden tool is any one of many tools made for gardening and landscaping, which overlap with the range of tools made for agriculture and horticulture. Garden tools can be divided into hand tools and power tools. Hand tools Today's garden tools originated with the earliest agricultural implements used by humans. Examples include the hatchet, axe, sickle, scythe, pitchfork, spade, shovel, trowel, hoe, fork, and rake. In some places, the machete is common. The earliest tools were made variously of wood, flint, metal, tin, and bone. The development of metalworking, first in copper and later in bronze, iron, and steel, produced today's durable tools, including such efficient cutting tools as pruning shears (secateurs – for example anvil pruners), grass shears, and loppers. Increasing use of modern alloys allows many tools to be made both stronger and lighter, making them more durable and easier to use. Ergonomics Some modern tool designs reflect ergonomic cons ...

Plant Nursery
A nursery is a place where plants are plant propagation, 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 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 trees, of particular varieties for purposes such as fruit trees for orch ...

Gardener
A gardener is someone who practices gardening, either professionally or as a hobby. Description A gardener is any person involved in gardening, arguably the oldest occupation, from the hobbyist in a residential garden, the home-owner supplementing the family food with a small Kitchen garden, vegetable garden or orchard, to an employee in a plant nursery or the head gardener in a great house, large estate. Garden design and maintenance The garden designer is someone who will design the garden, and the gardener is the person who will undertake the work to produce the desired outcome. Design The term gardener is also used to describe garden designers and landscape architects, who are involved chiefly in the design of gardens, rather than the practical aspects of horticulture. Garden design is considered to be an art in most cultures, distinguished from gardening, which generally means ''garden maintenance''.

Orchard
An orchard is an intentional plantation of trees or shrubs that is maintained for food production. Orchards comprise fruit tree, fruit- or nut (fruit), nut-producing trees that are generally grown for commercial production. Orchards are also sometimes a feature of large gardens, where they serve an aesthetic as well as a productive purpose. A fruit garden is generally synonymous with an orchard, although it is set on a smaller, non-commercial scale and may emphasize berry shrubs in preference to fruit trees. Most temperate-zone orchards are laid out in a regular grid, with a grazed or mown lawn, grass or bare soil base that makes maintenance and fruit gathering easy. Most modern commercial orchards are planted for a single variety of fruit. While the importance of introducing biodiversity is recognized in forest plantations, introducing genetic diversity in orchard plantations by interspersing other trees might offer benefits. Genetic diversity in an orchard would provide resili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunk (botany)
Trunks are the Plant stem, stems of woody plants and the main structural element of trees. The woody part of the trunk consists of dead but structurally significant heartwood and living sapwood, which is used for nutrient storage and transport. Separating the wood from the bark is the Vascular cambium, cambium, from which trunks grow in diameter. Bark is divided between the living inner bark (the phloem), which transports sugars, and the outer bark, which is a dead protective layer. The precise Cell (biology), cellular makeup of these components differs between non-flowering plants (gymnosperms) and flowering plants (Flowering plant, angiosperms). A variety of specialised cells facilitate the storage of carbohydrates, water, minerals, and transport of water, minerals, and hormones around the plant. Growth is achieved by Cell division, division of these cells. Vertical growth is generated from the Meristem, apical meristems (stem tips), and horizontal (radial) growth, from the c ...
