Pruned
Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots. The practice entails the ''targeted'' removal of diseased, damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants. Some try to remember the categories as "the 4 D's": the last general category being "deranged". 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. In nature, meteorological conditions such as wind, ice and snow, and salinity can cause plants to self-prune. This natural shedding is called abscission. Specialized pruning practices may be appl ...

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 counter t ...

Salt Pruning
Salt pruning is the process by which saline mists generated by seawater are driven ashore by winds and thus over time alter the shape of trees or shrubs. The process degrades foliage and branches on the windward side of the plant that faces the body of saline water, more than it does the foliage on the landward side. The resultant growth form is asymmetrical, appearing "swept back" away from the ocean. Examples There are numerous examples worldwide of this phenomenon. In the eastern United States on Long Island occurrences of salt-pruned ''Quercus stellata'' are observable in Flax Marsh. In San Diego County, California, a colony of ''Pinus torreyana'' has been salt-pruned by spray from the Pacific Ocean.C. Michael Hogan (2008"Torrey Pine: ''Pinus torreyana.''" Globaltwitcher, ed.

Ice Pruning
Ice pruning is the natural process of selective vegetative pruning on the windward side of a plant, executed by the impact of ice and snow particles driven by wind.William M. Marsh (1978) ''Environmental Analysis: For Land Use and Site Planning'', McGraw-Hill, 292 pages The process is sometimes termed snow pruning. The time scale required for this phenomenon is typically over several growing seasons. The characteristic asymmetry of an ice-pruned plant is achieved only if the prevailing winds during the snow season have a definite directional bias, as shown on a wind rose. Ice pruning is seen in high latitudes and altitudes, such as high mountain slopes and locations more than 50 degrees of latitude from the equator. In parts of northern Canada, forests dominated by Black Spruce have been noted for containing individual trees that are distinctively ice-pruned.C.

Abscission
Abscission () is the shedding of various parts of an organism, such as a plant dropping a leaf, fruit, flower, or seed. In zoology, abscission is the intentional shedding of a body part, such as the shedding of a claw, husk, or the autotomy of a tail to evade a predator. In mycology, it is the liberation of a fungal spore. In cell biology, abscission refers to the separation of two daughter cells at the completion of cytokinesis. In plants Function A plant will abscise a part either to discard a member that is no longer necessary, such as a leaf during autumn, or a flower following fertilisation, or for the purposes of reproduction. Most deciduous plants drop their leaves by abscission before winter, whereas evergreen plants continuously abscise their leaves. Another form of abscission is fruit drop, when a plant abscises fruit while still immature, in order to conserve resources needed to bring the remaining fruit to maturity. If a leaf is damaged, a plant may also abscis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epicormic Shoot
An epicormic shoot is a shoot growing from an epicormic bud, which lies underneath the bark of a trunk, stem, or branch of a plant. Epicormic buds lie dormant beneath the bark, their growth suppressed by hormones from active shoots higher up the plant. Under certain conditions, they grow into active shoots, such as when damage occurs to higher parts of the plant, or light levels are increased following removal of nearby plants. Epicormic buds and shoots occur in many woody species, but are absent from many others, such as most conifers. Function Human horticultural practices that exploit epicormic growth rely on plants that have epicormic budding capabilities for regenerative function in response to crown damage, such as through wind or fire. Epicormic shoots are the means by which trees regrow after coppicing or pollarding, where the tree's trunk or branches are cut back on a regular cycle. These forestry techniques cannot be used on species which do not possess strong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arborist
An arborist, tree surgeon, or (less commonly) arboriculturist, is a professional in the practice of arboriculture, which is the 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 (forestry or silviculture). An arborist's scope of work is therefore distinct from that of either a forester or a 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). Arborists who climb (as no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvest
Harvesting is the process of gathering a ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. On large mechanized farms, harvesting uses the most expensive and sophisticated farm machinery, such as the combine harvester. Process automation has increased the efficiency of both the seeding and harvesting processes. Specialized harvesting equipment utilizing conveyor belts to mimic gentle gripping and mass-transport replaces the manual task of removing each seedling by hand. The term "harvesting" in general usage may include immediate postharvest handling, including cleaning, sorting, packing, and cooling. The completion of harvesting marks the end of the growing season, or the growing cycle for a particular crop, and the social importance of this event makes it the focus of seasonal celebrati ...

Transplanting
In agriculture and gardening, transplanting or replanting is the technique of moving a plant from one location to another. Most often this takes the form of starting a plant from seed in optimal conditions, such as in a greenhouse or protected Plant nursery, nursery bed, then replanting it in another, usually outdoor, growing location. The Agricultural machinery, agricultural machine that does this is called a transplanter. This is common in market gardening and truck farming, where setting out or planting out are synonymous with transplanting. In the horticulture of some ornamental plants, transplants are used infrequently and carefully because they carry with them a significant risk of killing the plant.Basics of horticulture - Simson, Straus. Oxford Book Company, Edition 2010 Transplanting has a variety of applications, including: * Season extension, Extending the growing season by starting plants indoors, before outdoor conditions are favorable; * Protecting young plants from ...

Plant 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 tree ...
