Landscape Architecture

Landscape architecture involves the design of landmarks, outdoor spaces, and structures to make an environment beautiful to achieve specific social or environmental objectives. Landscape architecture involves the examination of current soil, ecological and social processes, conditions in a landscape. Landscape architecture involves site planning, residence landscape planning, green infrastructure planning, landscape design, planning of recreation centers and parks, managing stormwater, restoration of environments, management of visual resources etc. Professionals in the field of landscape architecture are called landscape architects.

Landscape architecture incorporates various fields. It involves fine art, ecology, soil science, architecture, botany, geography, industrial design, civil engineering, horticulture etc. Landscape architects design public infrastructure, design residential areas, design parkways and parks, design forest reserves, manage conservation areas, reclaim landscapes, design car parks for corporate and public buildings remove toxins from rainwater, secure public and private buildings, reclaim degraded areas like wetlands and mines among other functions. They focus on the landscapes of various external spaces and structures. They work with various materials and can work on small designs, rural designs, soft and hard materials etc. with a lot of focus on green effects and environmental impact.

Landscape architects are creative people that conceptualize designs and ideas and bring them to life. From their designs, they come up with technical design drawings with accurate specifications and measurements. They also serve as consultants and they review proposals. They conduct environmental audits and assessments, and they also serve as witnesses on legal cases that involve outdoor spaces and landscapes.

Landscape architects work in various rural and urban environments with all kinds of structures, both private and public. Landscape architecture is focused on creating a balance between natural and manmade environments.

To become a landscape architect, one needs to obtain a Bachelor of Science degree, and/or Master’s degree in landscape architecture. They also need to get a license before they can practice in the United States. To get their license, they finish from a university, get some work experience, pass a tough exam and take a lot of further educational courses. Landscape architects take course work in the subjects like psychology, preservation of historical sites, planning, horticulture, site design, drainage etc.

Landscape architects are different from other landscape professionals and should not be confused with others. They are strictly designers and architects and not builders. This is the same way architects are different from structural engineers and builders. Or the way computer scientists are different from computer engineers. They work hand in hand with other professionals to bring landscape designs to life.

How landscape Architects Accomplish Projects in Landscape Architecture

Landscape architects is more complex than mere doodling or making sketches on paper. It is an intricate work that involves a lot of precision. They need to take various steps to bring designs to life and create large-scale landscape projects. The following are the steps that landscape architects take to bring a design to life.

  1. They learn more about a landscape: At the beginning of a project, a landscape architect must first know all they can about a project and the requirements of their client. They visit the proposed site, carry out analysis, ask relevant questions, check legal and building codes and research the history of a site.
  2. Conceptualization: In this phase, a landscape architect starts to come up with concepts for the project. They decide whether to create 3D models or use their drawings alone, they decide what green living concepts to implement and they look at what structures to add or remove. They also seek for public input, especially for public projects.
  3. Design: Here, designs are drawn, and computer models are built to show simulations of the project. First, some initial drawings are made to cover a project. After the client approves the drawings, special construction drawings are then made. These plans are well detailed and show how every aspect of the project will be constructed, the type of materials to be used and the exact position and specification of everything in the project down to the tiniest detail.
  4. Construction: Even though the landscape architect has done most of his/her work, they still need to visit the site and see how the construction is going. They ensure that deviations are not made, and they provide support where they can. They also help to solve problems that may arise. When the project is completed, they carry out a final inspection. They may even be retained to help with maintenance of the site. Some towns and cities have landscape architects in their payroll that help with management of parks, landscapes and other public spaces.

Landscape architects find employment in various places. They can be employed in public and private organizations. They work in landscape architectural, engineering and planning firms. They work with other private organizations in physical planning departments and companies that offer services related to land development and planning.

Within the public sector, landscape architects find employment opportunities within state, regional, federal and other regional agencies that handle land development, preservation and planning. Some popular agencies that employ landscape architects are the Veteran Administration, the National Park Service, the Bureau of Land Management, the Department of Transportation, the Soil Conservation Bureau, the US Army Corps of Engineers and the United States Forest Service.

Landscape architects also find a lot of employment in the academic field where they lecture the next generation of landscape architects and carry out academic research in colleges and universities. They also lecture in community colleges and continuing education programs. They are found in the department of art, architecture, estate management, urban and regional planning and other related fields.

All You Need to Know About Soil for a Landscape Architect

Landscape architect tips: Understanding Exposure of Plants to The Sun

When making garden design plans, it is important to determine how much shade and sun your garden receives.

There are some plants that require partial sun while some require full sun. There are even some that will survive with full shade. A landscape architect usually uses a compass to determine the direction that borders or areas will face in a garden design plan. Those that face the north will be in the shade for most parts of the day while those facing the south will be in the sun for most of the day. Those that face the east will have morning sun and evening shade. Those that face the west will experience the opposite of those that face the east.

Plants that thrive in sun in landscape architect

The patterns of shade and sun will change during the day. A garden that is in full sun at midday will experience areas of shade in the late afternoon and the morning. A landscape architect needs to study the garden on a sunny day and understand the way shadows move around the garden. Sunlight movement is different for various seasons. An area that is in the shade during the summer could be in the sun in the summer. This could affect evergreen plants that require constant sunlight to survive.

Growing shade-lovers garden design

No matter the amount of sun that a garden receives, there are always various plants that will survive in such conditions. There are plants that will thrive in both sun and shade and a mixture of both.

Microclimates in a Garden Should be Examined

The varying conditions in different parts of a garden are known as microclimates. These could include sheltered hotspots by a warm wall, areas with frost at the bottom of a slope and areas with lots of wind and areas that are exposed. The proper study of microclimates will help landscape designers grow various plants. The various water levels, air, wind circulation and temperature should be studied.

Various Types of Soil

To grow healthy plants in a garden, a landscape architect must find out the soil type that is in a garden. It is best to select plants that will grow in a particular soil type rather than trying to grow plants that will not thrive in a soil type.

There are three major types of soil. They are clay, silt and sandy. They are identified by the size of their particles. The size of their particles will determine the amount of plant food and water that they can hold.  Most gardens have a combination of clay and sandy soil. One of the two is usually more abundant than the other. The perfect garden soil is loamy which is a combination of both sandy and clay soil in roughly equal amounts.

Sandy Soil

Sandy soil has particles that are relatively large and water drains easily through the large spaces between them. The soil drains water easily. The plant nutrients dissolve in the water so the soil is not fertile. Sandy soil is great for Mediterranean plants.

Clay Soil

Clay soil has particles that are very tiny. The particles can store moisture in the gap between them. Clay soil retains water easily due to its porous particles. It is very rich in nutrients. But when they are wet, clay soils could get waterlogged and they can form impenetrable crusts when they are dry. They are perfect for hungry plants like fruit trees.

Silt Soil

Silt soil is usually difficult to find. It can be found on river plains. They have a high nutrient content, and they can become waterlogged and compact like clay soil. Loam soil has roughly equal amounts of clay and sandy soil. They are the best of the lot. They retain enough water for the roots of plants to absorb and they allow any excess moisture to drain away, so they do not get waterlogged. They hold on to nutrients to well making them the perfect garden soil.

Types of soils for your garden design for a landscape architect

How to Improve Your Soil

You need to improve your soil regardless of your soil type. It doesn’t matter if you have a clay soil, sandy soil or dry soil, your plants will become better if you apply a lot of organic matter to the soil. You can apply garden compost, farmyard manure that has been left to rot and mushroom compost. The organic matter will open up clay soils and allow them to drain water easily. They will also coat sandy soil and help them to retain water. The organic matter can be dug into the soil when preparing for planting, or they can be laid as a thick layer of mulch. Microorganisms and worms will then work the organic matter into the soil.

If you add horticultural grit to clay soils, you can improve the drainage and structure of the soil. The grit can be dug into the soil over a large area. In tough cases, soils that are very heavy and waterlogged might need to be drained.

pH of a soil

The pH of a soil is a measure of the alkalinity or acidity of a soil. It affects the kind of plants that can be grown successfully in the soil. pH is measured on a scale of 1 to 14. Instead a pH of 7 means that the soil is neutral. A pH higher than 7 means that the soil is alkaline. A pH lower than 7 means that the soil is acidic. A soil test will measure the pH of a soil accurately.

There are plants that require a specific type of soil to grow. There are other plants that can grow in any pH range. The pineapple broom (Cytisus battandieri) and lilacs (Syringa vulgaris) grow best in alkaline soil while Rhododendrons, azaleas, and heathers (Erica) grow best in acidic soil.

Silty and Sandy soil

Silty soil is silky to the fingers while sandy soil is gritty between the fingers. When rolled into a ball, both of them will fall apart. Sandy soil is easy to dig and it gets warm easily in spring. Borderline hardy plants survive better in these soils that are dry.

Clay Soil

Clay soil is dense, sticky and smooth. When rolled into a ball, it retains its shape. When it is even rolled into the shape of a horseshoe, it retains its shape. Clay soil is also called heavy because it is difficult to dig.

How to Use a pH test Kit

You can get a pH test kit from a garden center. You will place a sample of the soil in the tube and then you add the solution that comes with the kit. When the color of the solution changes, you can match it to the chart. You can take a few different readings from various areas of the garden since they could have various pH values.
