A nursery is a place where plants are propagated and grown to a desired age. 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.

Nurseries may supply plants for gardens, agriculture, forestry and conservation biology. Some of them specialize in one phase of the process: propagation, growing out, or retail sale; or in one type of plant: e. Some produce bulk stock, whether seedlings or grafted, of particular varieties for purposes such as fruit trees for orchards, or timber trees for forestry.

Some produce stock seasonally, ready in springtime for export to colder regions where propagation could not have been started so early, or to regions where seasonal pests prevent profitable growing early in the season. Nurseries grow plants in open fields, on container fields, in tunnels or greenhouses.

In open fields, nurseries grow decorative trees, shrubs and herbaceous perennials. On a containerfield nurseries grow small trees, shrubs and herbaceous plants, usually destined for sales in garden centers. These have proper ventilation, sunlight etc. Plants may be grown by seed s. These can be taken from shoot tips or from roots etc.

By these methods plants are grown in nurseries and gardens. With the objective of fitting planting stock more ably to withstand stresses after outplanting, various nursery treatments have been attempted or developed and applied to nursery stock. Buse and Day , [1] for instance, studied the effect of conditioning of white spruce and black spruce transplants on their morphology, physiology, and subsequent performance after outplanting. Root pruning and wrenching modified stock in the nursery by decreasing height, root collar diameter, shoot:root ratio, and bud size, but did not improve survival or growth after planting.

Fertilization reduced root growth in black spruce but not of white spruce. Seedlings vary in their susceptibility to injury from frost. Damage can be catastrophic if "unhardened" seedlings are exposed to frost. Frost hardiness may be defined as the minimum temperature at which a certain percentage of a random seedling population will survive or will sustain a given level of damage Siminovitch , Timmis and Worrall In an earlier technique, potted seedlings were placed in a freezer chest and cooled to some level for some specific duration; a few days after removal, seedlings were assessed for damage using various criteria, including odour, general visual appearance, and examination of cambial tissue Ritchie Stock for fall planting must be properly hardened-off.

Conifer seedlings are considered to be hardened off when the terminal buds have formed and the stem and root tissues have ceased growth. Other characteristics that in some species indicate dormancy are color and stiffness of the needles, but these are not apparent in white spruce.

Whether in the forest or in the nursery, seedling growth is fundamentally influenced by soil fertility , but nursery soil fertility is readily amenable to amelioration, much more so than is forest soil. Nitrogen , phosphorus , and potassium are regularly supplied as fertilizers, and calcium and magnesium are supplied occasionally. Applications of fertilizer nitrogen do not build up in the soil to develop any appreciable storehouse of available nitrogen for future crops.

Fertilization permits seedling growth to continue longer through the growing season than unfertilized stock; fertilized white spruce attained twice the height of unfertilized. Nutrients in oversupply can reduce growth [9] [10] or the uptake of other nutrients. Nursery stock size typically follows the normal curve when lifted for planting stock. The runts at the lower end of the scale are usually culled to an arbitrary limit, but, especially among bareroot stock, the range in size is commonly considerable.

The stock was regraded into large, medium, and small fractions according to fresh weight. Without site preparation, large stock were more than twice the size of small stock after 10 years. The value of large size at the time of planting is especially apparent when outplants face strong competition from other vegetation, although high initial mass does not guarantee success.

The nursery stock was grown at Midhurst Forest Tree Nursery, and carefully handled through lifting on 3 lift dates, packing, and hot-planting into cultivated weed-free loam. The 1. Lifting date had no significant effect on growth or survival.

High elevation sites in British Columbia's southern mountains are characterized by a short growing season, low air and soil temperatures, severe winters, and deep snow. The survival and growth of Engelmann spruce and subalpine fir outplanted in 3 silvicultural trials on such sites in gaps of various sizes were compared by Lajzerowicz et al. Lajzerrowicz et al. Concluded that plantings of conifers in clearcuts at high elevations in the southern mountains of British Columbia are likely to be successful, even close to timberline; and group selection silvicultural systems based on gaps 0.

Gaps smaller than 0. Planting stock, "seedlings, transplants, cuttings, and occasionally wildings, for use in planting out," [20] is nursery stock that has been made ready for outplanting. The amount of seed used in white spruce seedling production and direct seeding varies with method. A working definition of planting stock quality was accepted at the IUFRO Workshop on Techniques for Evaluating Planting Stock Quality in New Zealand: "The quality of planting stock is the degree to which that stock realizes the objectives of management to the end of the rotation or achievement of specified sought benefits at minimum cost.

Quality is fitness for purpose. A distinction needs to be made between "planting stock quality" and "planting stock performance potential" PSPP. The actual performance of any given batch of outplanted planting stock is determined only in part by the kind and condition, i. The PSPP is impossible to estimate reliably by eye because outward appearance, especially of stock withdrawn from refrigerated storage, can deceive even experienced foresters, who would be offended if their ability were questioned to recognize good planting stock when they saw it.

Prior to Wakeley's [24] demonstration of the importance of the physiological state of planting stock in determining the ability of the stock to perform after outplanting, and to a considerable extent even afterwards, morphological appearance has generally served as the basis for estimating the quality of planting stock. Gradually, however, a realization developed that more was involved. Tucker et al. The intuitive "stock that looks good must be good" is a persuasive, but potentially dangerous maxim.

That greatest of teachers, Bitter Experience, has often enough demonstrated the fallibility of such assessment, even though the corollary "stock that looks bad must be bad" is likely to be well founded. The physiological qualities of planting stock are hidden from the eye and must be revealed by testing.

The potential for survival and growth of a batch of planting stock may be estimated from various features, morphological and physiological, of the stock or a sample thereof. The size and shape and general appearance of a seedling can nevertheless give useful indications of PSPP. In low-stress outplanting situations, and with a minimized handling and lifting-planting cycle, a system based on specification for nursery stock and minimum morphological standards for acceptable seedlings works tolerably well.

Length of leading shoot, diameter of stem, volume of root system, shoot:root ratios, and height:diameter ratios have been correlated with performance under specific site and planting conditions. Schmidt-Vogt , [28] for instance, found that whereas mortality among large outplants is greater than among small in the year of planting, mortality in subsequent growing seasons is higher among small outplants than among large. Much of the literature on comparative seedling performance is clouded by uncertainty as to whether the stocks being compared share the same physiological condition; differences invalidate such comparisons.

Height and root-collar diameter are generally accepted as the most useful morphological criteria [30] and are often the only ones used in specifying standards. Quantification of root system morphology is difficult but can be done, e.

Planting stock is always subject to a variety of conditions that are never optimal in toto. The effect of sub-optimal conditions is to induce stress in the plants. The nursery manager aims, and is normally able to avoid stresses greater than moderate, i. The adoption of nursery regimes to equip planting stock with characteristics conferring increased ability to withstand outplanting stresses, by managing stress levels in the nursery to "condition" planting stock to increase tolerance to various post-planting environmental stresses, has become widespread, particularly with containerized stock.

Outplanted stock that is unable to tolerate high temperatures occurring at soil surfaces will fail to establish on many forest sites, even in the far north. HSPs, present constitutively in black spruce and many other, perhaps most, higher plants [34] [35] [36] [37] are important both for normal cell functioning and in a stress response mechanism following exposure to high, non-lethal temperature.

In black spruce at least, there is an association between HSPs and increased levels of heat tolerance. HSP 73 was detected in black spruce nuclear, mitochondrial, microsomal, and soluble protein fractions, while HSP 72 was observed only in the soluble protein fraction. Heat shock affected the abundance of HSPs depending on protein fraction and time of day. Without heat shock, nuclear membrane-bound HSP 73 was absent from plants in the morning and only weakly present in the afternoon, and heat shock increased the abundance of nuclear membrane.

In the mitochondrial and microsomal protein fractions, an afternoon heat shock reduced HSP 73 , whereas a morning heat shock increased HSP 73 in the mitochondrial but decreased it in the microsomal fraction. In all instances, shoot and root heat tolerances were significantly greater in the afternoon than in the morning. Planting stock continues to respire during storage even if frozen. Navratil [40] found that closed containers in cold storage averaged internal temperatures 1.

Depletion of reserves can be estimated from the decrease in dry weight. The propensity of a root system to develop new roots or extend existing roots cannot be determined by eye, yet it is the factor that makes or breaks the outcome of an outplanting operation.

The post-planting development of roots or root systems of coniferous planting stock is determined by many factors, some physiological, some environmental. New root growth can be assumed to be necessary for successful establishment of stock after planting, but although the thesis that RGC is positively related to field performance would seem to be reasonable, supporting evidence has been meager.

The physiological condition of seedlings is reflected by changes in root activity. This is helpful in determining the readiness of stock for lifting and storing and also for outplanting after storage. Root regenerating research with white spruce in Canada Hambly , Day and MacGillivray , Day and Breunig [42] [43] [44] followed similar lines to that of Stone's [45] pioneering work in California. Simpson and Ritchie [46] debated the proposition that root growth potential of planting stock predicts field performance; their conclusion was that root growth potential, as a surrogate for seedling vigor, can predict field performance, but only under such situations as site conditions permit.

Survival after planting is only partly a function of an outplant's ability to initiate roots in test conditions; root growth capacity is not the sole predictor of plantation performance. Some major problems militate against greater use of RGC in forestry, including: unstandardized techniques; unstandardized quantification; uncertain correlation between quantified RGC and field performance; variability within given, nominally identical, kinds of planting stock; and the irrelevance of RGC test values determined on a sub-sample of a parent population that subsequently, before it is planted, undergoes any substantive physiological or physical change.

In its present form, RGC testing is silviculturally useful chiefly as a means of detecting planting stock that, while visually unimpaired, is moribund. Seedling moisture content can be increased or decreased in storage, depending on various factors including especially the type of container and the kind and amount of moisture-retaining material present.

When seedlings exceed 20 bars PMS in storage, survival after outplanting becomes problematical. The Relative Moisture Content of stock lifted during dry conditions can be increased gradually when stored in appropriate conditions. Bareroot 1. During the growing season, g increased to about 0. Minimum xylem pressure potential PSIm was initially During the first half of the growing season, PSIm was below turgor loss point.

The osmotic potential at turgor loss point decreased after planting to In the greenhouse, minimum values of PSIT were Available turgor TA , defined as the integral of turgor over the range of RWC between PSIb and xylem pressure potential at the turgor loss point was 4. The stomata of both white and black spruce were more sensitive to atmospheric evaporative demands and plant moisture stress during the first growing season after outplanting on 2 boreal sites in northern Ontario than were jack pine stomata, [50] physiological differences that favoured growth and establishment being more in jack pine than in the spruces.

Ornamental horticulture consists of floriculture and landscape horticulture. Each is concerned with growing and marketing plants and with the associated activities of flower arrangement and landscape design. The turf industry is also considered a part of ornamental horticulture.

Spice Plant. What Is a Native Plant? Why Native Plants?

Proper planting is essential for healthy, vigorous growth of ornamental plants in the landscape. It assures rapid plant establishment by providing a favorable environment for the developing root system. Planting involves more than merely digging a hole and sticking a plant in it. Giving careful consideration to the preparation of the planting site, the time of year for best plant establishment and the handling requirements of different nursery stock will help you avoid problems later on. Before planting, survey the site for potential hazards to plant growth. For instance, new construction sites are often littered with pieces of mortar, plaster or limestone, creating an alkaline soil condition and inhibiting a plant's ability to absorb nutrients. Chemical spills, such as motor oil or gasoline, can also impair plant growth. It may be necessary to remove the top 6 to 8 inches of soil and replace it with a good grade of topsoil. Compacted soils also inhibit root growth. Poorly drained soils cause plant problems. Waterlogged soil will suffocate the root system and kill a plant.
