DESIGN PRINCIPLES IN GARDEN-MAKING

by Linda Engstrom, APLD


Since the space that the garden occupies is three-dimensional, the starting point of design is to get inside that space and create it from within. Imagine being inside a piece of sculpture. The developing space needs to evolve to accommodate the use, comfort and pleasure of its creator. The design elements are then employed to determine the way space will be perceived. All artists- photographers, painters, weavers, sculptors…and yes, garden-makers…use these same principles to create something magical.

A garden arbor helps define outdoor space in both Winter and Summer


Line is impressed upon all of us from earliest childhood --remember defining objects with connect-the-dots drawings, or the burden of having to carefully color inside the lines? Later one had to learn to write letters on a straight line as well as discovering just what the horizon line meant. In garden design, the form of a line creates a sense of direction as well as a sense of movement. The eye automatically follows a garden line, whether it be the edge of a walkway, the curve of a flower bed, or the outline of plant materials. The character of a line yields specific responses. Gentle, slow curves and horizontal lines tend to be experienced as restful while jagged diagonals or vertical lines create more excitement and tension.

Form, the shape defined by line, is probably the most enduring element in garden design. It is what is seen when first looking at a garden from a distance. Every plant has a distinct growth-habit, a unique mass and volume which develops and changes as the plant matures. These shapes, whether pyramidal, weeping, columnar, spreading, or round, divide and define the spaces in the garden. Some forms are more dramatic than others and so attract attention. The siting of a specific plant may block a view, or open a sight-line, or alter the view depending on the maturity and growth-habit of the plant--open or compact, herbaceous, evergreen or deciduous. These plant qualities often change with the seasons and restructure the lines of the garden. The form of the plants selected and their placement are critical to creating comfortable, dynamic spaces and pleasing silhouettes.


Texture in the garden creates sensual and visual excitement. It is generally read as the mass and void of foliage, bark, or flowers and changes with the light during the day and with the seasons. Up close, the size and shape of the leaves and twigs become the predominant textural elements of a plant. From a distance, it is the quality of light and shadow on the entire form, the patterns of light and dark, that translates as texture. Rough, coarse textures tend to create an informal mood and are visually dominant, while fine, smooth textures are associated with formal, elegant, subdued moods and are visually more passive. Fine-textured plants are visually translated as being farther away, so fine textures can be a tool for providing a sense of perspective in a small garden and making the space appear larger. On the other hand, the predominance of coarse-textured plants make a garden space appear smaller. Strong textural contrasts add drama and interest to a garden. Bark and foliage are two ways of adding textural interest to any space. Foliage and Spring flowers, with both textural and color interest, are shown in a May garden.........


Scent in a garden is often neglected. Introducing a variety of fragrances will bring an extra dimension to the garden by expanding sensory awareness. If the garden is exposed fragrant plants may need to be located in a sheltered location. The scent of delicately fragrant plants is also more appreciated if they are located near a path or at the edge of a patio or entry area. Specific fragrances, like colors, evoke emotional responses and can help create a certain mood or sense of time in the garden.

Color is often a confusing and puzzling design element for many gardeners. On the other hand it seems to be the one and only element some gardeners consider when planning a garden. Although color is a key element in the design of a garden, many give it too great an importance and fret continually about the often complex rules which some designers have propounded. One of the following three widely employed formulas for planning color in the garden are best used:

1. Design in a green monotone with only an occasional splash of another color, as exemplified in traditional Japanese gardens.

2.Translate from nature, using harmonies of colors, or kaleidoscopic patterns as might be found in a wildflower meadow.

3. Use the artist's color wheel and paint pictures in the palette-gardening approach made famous by Gertrude Jekyll.

The gardener's final choice of a formula is dictated by location, the size of the garden, and the kind of garden wanted. Living in the countryside just outside of Portland, Oregon, I prefer to translate from nature so that my garden blends in with the natural beauty of the area. But since I also have acres of ground at my disposal I have room for many flower and mixed borders. In designing them I develop specific color schemes using the palette approach, creating for example, a white garden or a blue border. Generally, the more area to be dealt with the more complex the color scheme can be. A garden created in limited space will be more dramatic if the color scheme is kept as simple as possible.

Research has identified the emotional responses specific colors typically generate. The bright reds, yellows, and oranges tend to excite. The softer blues, pinks, greens, and violets produce a calming, tranquil effect. This is one reason why the monochromatic green gardens of the Japanese are so revered. The 'music of the color green' is a phrase often heard in reference to the basic garden color green broken into numerous tones ranging from blue-green to yellow-green . White tends to be the great unifier, providing a neutral, yet somewhat uplifting spirit. Gardeners need to employ an awareness of color responses when planning the functional needs of garden spaces. In general, warm colors -red, yellow, orange- attract the eye, standing out or advancing. Cool colors -blues, most violets and some greens- recede into the landscape. Color therefore contributes to a sense of depth by defining spatial relationships. Remember too that colors in the landscape are not static, changing with the time of day, cloud cover, and season. Color intensity directly relates to the amount of reflected light. Flower color is transient, while foliage, bark, seed pods, and berries provide color highlights and interest at other times of the year, so must loom large in design considerations.

To create a garden space satisfying to the senses and imparting a feeling of unity with the environment, gardeners must also consider six basic principles of design: repetition, variety, balance, emphasis, sequence, and scale.

Repetition is the continuing thread in a garden and is generally defined as duplication. When any design element is repeated the mind is better able to understand the composition as a whole and so a sense of order is introduced.. It is the qualities or character of an object--line, form, texture, scent or color- that are usually repeated. Repeating finely textured plants in a garden helps to unify the design and impart a powerful sense of simplicity. Repetition is simply a matter of holding one design quality constant while varying the others. A word of caution: If repetition is carried to extremes the garden will become either monotonous or so subtle that the viewer only sees disorder.

Variety is the life of the garden. The design qualities of line, form, texture, scent, and color are changed and contrasted to provide diversity and avoid uniformity. Diversity develops a tension which helps to hold the observer's attention while creating excitement and enjoyment. Variety is the opposite of repetition. But when it is overdone by adding too many elements, chaos results, so a very fine balance between repetition and variety is needed to achieve unity in a landscape.

Balance refers to the stability or repose of the garden, and is realized by creating an equilibrium between the parts that make up the whole. Line, form, texture, scent, and color all attract our attention so these sensual energies must be gauged and then balanced out. One form of balance relates to layout along a preconceived central axis. That axis can either be informal or formal in its arrangement. Formal or symmetrical arrangements are exactly the same on either side of the axis, while informal or asymmetrical arrangements are unlike on either side of the axis. Another way of conceiving an axis is in the vertical dimension. Natural, informal landscapes which are increasingly popular, depend upon balancing vertical and horizontal elements or small, dense masses balancing large, diffuse groupings. In all cases the elements being balanced must both hold the same importance in the eye.

Emphasis refers to those garden elements which initially seize attention and to which the eye continually returns. It is the creation of the more important and the less important elements in the garden. The parts of any composition should not be equal in their visual interest. Certain parts should be different, perhaps larger, of a contrasting color, form, fragrance, or texture than the rest, depending on the function of the design. Again, if too many elements are introduced the effect is lost. Emphasis can be achieved only by limiting the number of dominant design elements.

Sequence is the movement of the garden. It is the rhythms that develop when line, form, texture, and color are changed in a consistent way to lead in a particular direction or to a point of focus. Sequence helps to connect the various design elements. It can be achieved through repetition, being careful to avoid a monotonous repeat; or by progression, such as using textures in graded steps from fine to coarse; or by alternation, a repetition of two or more contrasting features.

Scale within the garden, as distinct from the overall scale of the garden as discussed earlier, refers to the harmony of the garden. That is, all the elements of a garden should agree in the sense they convey of the size of the whole. The actual size of an object is different from its relative scale or proportion in relation to other neighboring objects. So scale is concerned with the relationship between the size of an object to the size of the other objects within the same composition. Thus, a tiny alpine plant is out of scale among tall trees, just as it would be planted next to a large building.

With these general principles in mind, applied in connection with the elements of line, form, texture, scent, and color, a simple garden space can become a work of art.

Streptococcus pneumoniae bakterisi, zatürrenin yaygın nedenlerinden biridir.
Streptococcus pneumoniae bakterisi, zatürrenin yaygın nedenlerinden biridir.

Hastalık, beden veya zihinde meydana gelen, rahatsızlık, dert ve görev bozukluğuna yol açan belirli bir anormal duruma verilen isimdir. Bazen terim yaralanma, sakatlık, sendrom, semptom ve normal yapı ve fonksiyonun anormal çeşitlerini kapsayacak biçimde, geniş bir anlamda, kullanılır. Fakat farklı bağlamlarda bu kavramlar farklı kategorilere girerler ve hastalık kavramı bunların yerine kullanılamaz.

TDK tanımına göre "hastalık"; "Organizmada birtakım değişikliklerin ortaya çıkmasıyla sağlığın bozulması durumu, rahatsızlık, çor, dert, sayrılık, illet, maraz, maraza, esenlik karşıtı"dır.[1]

Hastalıkları inceleyen bilim dalı patolojidir. Hastalıkların sistematik sınıflandırmasını konu edinen bilim dalı ise nozolojidir. İnsan hastalıkları ve bunların tedavisiyle ilgilenen daha geniş bir alanı kapsayan bilim dalı ise tıptır. Birçok benzer (hatta bazı aynı) durum ve süreçler hayvanları da etkilemektedir; hayvanları etkileyen hastalıkları inceleyen bilim dalı veterinerliktir. Hayvanlar ve insanlar dışında, her organizma gibi, bitkiler de çeşitli süreç ve durumlardan etkilenip zarar görebilirler; enfeksiyon, besin yetersizliği veya zararlı mutasyonlar gibi. Bitkileri etkileyen hastalıkları inceleyen bilim dalı bitki patolojisidir.


Hastalığın İletimi - Bulaşıcılığı ve Epidemiyoloji

Bazı hastalıklar, bulaşıcıdır ve çeşitli mekanizmalar sayesinde iletilebilir , - bulaşabilirler;örneğin grip, öksürüklerden çıkan küçük damlacıklar, böcek veya diğer vektörlerin ısırıkları veya hastalığı taşıyan kirli su veya yiyecekler gibi.

Diğer hastalıklarsa, kanser ve kalp hastalığı gibi, mikroorganizmaların herhangi bir rolü olsa dahi bir enfeksiyon nedeniyle oluşmadıklarından, bulaşıcı değillerdir.

Epidemiyoloji [değiştir]

Epidemiyoloji, hastalıkların yayılışını ve salgın hastalıkları inceleyen, hastalıkların yayılmasını etkileyen çeşitli faktörleri saptayan tıp dalıdır. Ayrıca, epidemiyologlar hastalıkların yayılmasını kontrol altına alacak ve önleyecek metodlar geliştirmeye çalışırlar. Epidemiyolojik çalışmalar sonucu hastalıklar yayılımlarına göre endemik, epidemik veya pandemik olarak tanımlanabilir.

Endemik, bir nüfus (popülasyon) içinde her zaman var olan bir hastalığı tanımlar. Epidemik hızla, aniden ve beklenmedik bir şekilde yayılan ve birçok insanı etkileyen bir hastalık olarak tanımlanabilir. Fakat terim, daha önceden tahmin edilebilecek artışları kapsamaz; örneğin kışları grip vakalarının artışı epidemik olarak tanımlanmaz. Pandemik ise çok büyük alanlarda, bir kıta veya tüm dünya gibi, büyük sayıda insanı etkileyen hastalıkları tanımlar.

Terimin Farklı Kullanımları

Biyolojide, hastalık sözcüğü bir organizmanın işleyişine, görevine zarar veren her türlü anormal durumu tanımlamak için kullanılır.

Bugün hastalık sözcüğü mecazi olarak, herhangi bir şeyin düzensiz, işlevsiz veya sıkıntılı durumlarını belirtmek için kullanılır; "toplumun hastalığı" gibi. Ayrıca, Türkçe'de yine mecazi şekilde, hastalık sözcüğü "aşırı düşkünlük ve tutku" anlamında da kullanılır; "Temizlik hastalığı." gibi.

Gene therapy improves immune function in older children with SCID

Researchers at the National Institute of Allergy and Infectious Diseases and their colleagues studied three youth (ages 10, 11 and 14 years) who had X-linked severe combined immunodeficiency (SCID), in which there is little or no immune system function. The youth received gene therapy, similar to that used in younger children with SCID, to see if it would help improve their immune systems. Improvement was seen in the youngest child. The research shows that it is possible for gene therapy to improve immune function in older children with SCID. The research was published in the July 1, 2007, issue of Blood.

Fucosidosis

In this disorder, an enzyme (alpha-fucosidase) is missing in the body. Without it, the body can't finish breaking down certain sugar, fat, and protein molecules into their useful parts. The partially-broken-down molecules build up in cells throughout the body and damage them. This causes many types of symptoms.

FACES (Friends And Caregivers Encephalitis Survivors) welcomes anyone who has been touched by encephalitis including survivors, caregivers, family members and friends. Encephalitis is an inflammation of the brain, often caused by a virus. The Conference provides education and support to those coping with encephalitis and is active in raising awareness of this serious disease and the daily struggles that survivors and their families face.

August is Spinal Muscular Atrophy Awareness Month in U.S.

Families of Spinal Muscular AtrophySpinal muscular atrophy is a group of inherited disorders that destroys the nerves controlling voluntary muscle movement. There is no cure, but organizations such as Families of Spinal Muscular Atrophy and the International Alliance for Spinal Muscular Atrophy are working to advance research about the disorder.

Einsenmenger Syndrome

Ventricular septal defect may be present in Eisenmenger syndromeEisenmenger syndrome develops in individuals with significant heart defects. In Eisenmenger syndrome, blood pressure increases in the lungs (called pulmonary hypertension). Usually, the syndrome develops while individuals with heart defects are still children, but it may occur in adolescence or young adulthood.

Team identifies gene variant associated with sporadic ALS

ALS attacks the nerve cells (motor neurons) that control musclesAmyotrophic laterals sclerosis (ALS, or Lou Gehrig's disease) is either inherited (about 5 percent of cases) or occurs in a person with no family history of the disease (sporadic form). A team of researchers from various institutions, supported by a grant from the Muscular Dystrophy Association, did genetic analyses of 386 white patients with sporadic ALS and 542 neurologically normal white study participants. The researchers found 10 genetic sites that were associated with sporadic ALS, the most significant being one near a gene known as FLJ10986. The protein produced by this gene was found in the spinal cord and cerebrospinal fluid of both individuals with ALS and those who did not have it. The research provides new insights into the genetics of sporadic ALS and suggests that there is no single gene responsible for it. The research was published in The New England Journal of Medicine online August 1, 2007, and in print in the August 23, 2007, issue.

122 cases of West Nile virus in U.S., 3 deaths

West Nile virus is spread by infected mosquitoesAccording to the U.S. Centers for Disease Control and Prevention (CDC), the 2007 West Nile virus season has already seen reports of 122 human infections, leading to 3 deaths. States reporting infections include Alabama, Arizona, Arkansas, California, Colorado, Idaho, Illinois, Iowa, Kansas, Minnesota, Mississippi, Nebraska, Nevada, North Dakota, South Dakota, Texas, Utah, Virginia, and Wyoming. The number of infections this year is nearly four times that of 2006, says the CDC, although it's hard to predict how the rest of the season will be.

Children with Tourette's fast in certain language tasks

Children with Tourette syndrome have quicker grammar skills than their friendsNeuroscientists at Georgetown University Medical Center and the Kennedy Krieger Institute decided to study different aspects of language as a way to increase understanding of Tourette syndrome, a neurological disorder. They found that children with Tourette's are much quicker at processing certain mental grammar skills than are children without the disorder. The researchers suggest in their article, published in the July 2007 Neuropsychologia, that the brain abnormalities in Tourette syndrome may lead not only to tics, but also to a wider range of rapid behaviors that have not yet been discovered.
