Landscape Design

Competencies 17.00-21.00



What is landscaping l.jpg
What is Landscaping?

  • Landscaping is a profession that includes designing, installing, and maintaining the outdoor human environment.

  • There are 3 branches of the landscaping industry

    • Landscape Architecture

    • Landscape Contractors

    • Landscape Maintenance


Landscape architects l.jpg
Landscape Architects

  • Licensed professions

  • Conceptualize and plan the outdoor environment or landscape for residential and commercial clients.

  • Landscape designers usually do actual drawings for residential landscapes.


Landscape contractors l.jpg
Landscape Contractors

  • Carry out the installation or actual construction of the landscape plan

  • Often use subcontractors to do special work such as pools, electrical work, stonework, etc.


Landscape maintenance l.jpg
Landscape Maintenance

  • Extended care of existing landscapes

  • The care and upkeep of the landscape after installation


Design build firms l.jpg
Design-build Firms

  • Landscape businesses that handle everything from the initial contact with the client through design and construction as well as long-term care and maintenance.

Landscape Nursery Worker

  • Professional who sells and installs landscape plants and related materials.



Types of landscape plans10 l.jpg
Types of Landscape Plans

  • There are three types of plans used in landscaping

    • Sequential

    • Computer Assisted

    • Graphics



Sequential plans l.jpg
Sequential Plans

  • Each part of the plan is increasingly more specific and detailed.

  • Includes

    • Functional diagrams

    • Preliminary designs

    • Final Plans


Sequential plans functional diagrams l.jpg
Sequential Plans-Functional Diagrams

  • Begin the arrangement of the client’s program on the site.

  • Called “bubble diagrams” because they use loosely drawn freeform shapes to represent areas or spaces

  • Help the designer make decisions concerning layout and sizes and the use of each area.


Sequential plans preliminary designs l.jpg
Sequential Plans-Preliminary Designs

  • Break the “bubbles” to show first draft vision of how each landscape area will be shaped.

  • Landscape is given its form, type of materials to be used, and application of landscape design principles.

  • Simple without real details, but the horizontal and vertical relationships between objects and areas are now included.

  • A number of these may be shown before final plans are made.


Sequential plans final plans l.jpg
Sequential Plans-Final Plans

  • Use suggestions and reactions of the client to make a master drawing that is graphically detailed and specific in its intent for the landscape.

  • Include identified plants, paving patterns, and other specific information.

  • Can also include construction drawings for the landscape contractor or subcontractor

  • Graphics are designed to impress


Computer assisted l.jpg
Computer Assisted

  • Also called drawing board

  • CAD (Computer Aided Design) systems are accelerated drafting systems, designed to draw landscape plans using a personal computer.


Graphics l.jpg
Graphics

  • Consists of letters and numbers

    • Free-hand lettering

    • Mechanical lettering

    • Computer lettering

Principles of design l.jpg
Principles of Design

  • Balance

  • Focalization of Interest

  • Simplicity

  • Rhythm and Line

  • Proportion

  • Unity


Balance l.jpg
Balance

  • Materials are distributed evenly on opposite sides of a central axis

  • Three types of balance:

    • Symmetric

    • Asymmetric

    • Proximal/distal

  • Macro-range-the viewer sees the landscape from the most distant vantage point

  • Closer range-the views from other locations not as distant


Symmetric balance l.jpg
Symmetric Balance

  • One side is a reflective mirror image of the opposite side

  • Most formal type of balance


Asymmetric balance l.jpg
Asymmetric Balance

  • Each side has as much interest as the other

  • Not a duplicate of the other side


Proximal distal balance l.jpg
Proximal/Distal Balance

  • Balances right and left as well as near and far


Focalization of interest l.jpg
Focalization of Interest

  • Selects and positions visually strong items in the landscape composition to create focal points

  • Draws the eye of the viewer to one major feature in each use area

    • Example: corner planting


Simplicity l.jpg
Simplicity

  • Seeks to make viewers comfortable within the landscape

  • Excludes any unnecessary changes in shape, color, direction, etc.


Rhythm and line l.jpg
Rhythm and Line

  • Repeating something at a standard interval or pattern creates rhythm

  • Lines establish the shape and form of the landscape

  • Replicating strong existing lines such as the lines of a house or a pool

  • Functions of line plantings include foundation plantings, block a view, frame a view, and provide privacy.


Proportion l.jpg
Proportion

  • The size relationships between all the features of the landscape including vertical, horizontal, and spatial relationships


Proportion28 l.jpg
Proportion

  • Will maintain proper proportional relationships in a landscape between

    • Buildings and people

    • Buildings and plants

    • Plants and people

    • Plants and plants

    • Masses and soils


Unity l.jpg
Unity

  • All the separate parts contribute to the creation of the total design

  • Ties together individual parts of each area by:

    • Repeating prominent colors

    • Repeating construction materials

    • Continuing interior design themes to outdoor rooms

    • Repeat plant species

    • Raise patios, decks, and porches to door level


Landscape processes l.jpg
Landscape Processes

  • Process is a sequence of steps to reach a goal

  • There are three parts to the landscape process

    • Project development

    • Project maintenance

    • Design


Project development process l.jpg
Project Development Process

  • Includes determining need or objective

  • Design process

  • Accepting the design

  • Contracting and subcontracting

  • Landscaping

  • Acceptance

  • Billing and payment


Project maintenance process l.jpg
Project Maintenance Process

  • Determining need or desire

  • Selecting landscape maintenance company which assesses the needs and presents a proposal

  • If the proposal is accepted, the company schedules and does the work

  • Customer is billed


Design process l.jpg
Design Process

  • Site analysis and program analysis

  • Natural soils may be shallow or rocky

  • Natural outdoor soils may be subject to erosion

  • Weed and insect control is more difficult

  • Large areas of landscaping costs more

  • More labor is required to establish outdoor landscape



Planting ornamental plants l.jpg
Planting Ornamental Plants

  • Tools vary depending upon type and size of plants from bulb planter, trowel, spade, shovel to power augers and front end loaders.


Planting ornamental plants53 l.jpg
Planting Ornamental Plants

  • Hole should be larger than plant roots and soil prepared so that new roots will grow in it.

  • Methods of installation are determined by root form whether bare-rooted, balled-and-burlapped or containerized


Balled and burlapped plants l.jpg
Balled and Burlapped Plants

  • Balled and burlapped plants have a round soil ball of roots wrapped in burlap fabric.

  • Planted in flat-bottomed, straight-sided hole that is deeper and wider than the ball.

  • Backfill soil should fill the hole enough to raise the plant to the level at which it grew in the nursery.

  • Loose burlap around top of plant.

  • Mounded ring of soil around plant to catch water.



Containerized plants l.jpg
Containerized Plants

  • Use the same type hold, mounded ring, etc. as balled and burlapped.

  • In addition, the plant must be removed from the container

  • Roots should be unwound or cut at two inch intervals if pot-bound


Bare rooted plants l.jpg
Bare-rooted Plants

  • Have to have a mound or dome in the bottom of the hole to spread roots and direct roots to grow downward.


Planting ornamental plants58 l.jpg
Planting Ornamental Plants

  • Tall plants, even small trees, need to be staked to prevent blowing over.

  • Mulching should be done to help retain water, prevent weeds, improve appearance, and minimize temperature fluctuations.

  • Water adequately and frequently enough for healthy plants.


Handling ornamental plants l.jpg
Handling Ornamental Plants

  • Balled and burlapped plants should be handled by the root ball

  • Container grown plants should be handled by the container until removed and then by the root mass
