Sustainable Summerlin Gardening Practices

Sustainable landscaping is a modern type of gardening or landscaping that takes the environmental issue of sustainability into account. According to Loehrlein in 2009 this includes design, construction and management of residential and commercial gardens and incorporates organic lawn management and organic gardening techniques.^[1]

Definition

A sustainable garden is designed to be both attractive and in balance with the local climate and environment and it should require minimal resource inputs. Thus, the design must be “functional, cost-efficient, visually pleasing, environmentally friendly and maintainable".^[2] As part of sustainable development, it pays close attention to preserving limited resources, reducing waste, and preventing air, water and soil pollution. Compost, fertilization, integrated pest management, using the right plant in the right place, appropriate use of turf and xeriscaping (water-wise gardening) are all components of sustainable landscaping.

Benefits

Sustainability can help urban commercial landscaping companies save money.^[3] In California, gardens often do not outweigh the cost of inputs like water and labor. However, using appropriately selected and properly sited plants may help to ensure that maintenance costs are lower because of reduced inputs.

Long-lasting
Reduced water usage and no surface runoff or puddles
Minimal use of fertilizers and pesticides
Use of green waste
Conservation of energy and resources^[4]

Issues

Sustainability issues for landscaping include:

Non-sustainable practices include:

Consumption of non-renewable resources
Greenhouse gas emissions

Solutions

Some of the solutions are:

Reduction of stormwater run-off through the use of bio-swales, rain gardens and green roofs and walls.^[5]^[6]^[7]
Reduction of water use in landscapes through design of water-wise garden techniques (sometimes known as xeriscaping)^[8]^[9]^[10]^[11]
Bio-filtering of wastes through constructed wetlands^[12]
Irrigation using water from showers and sinks, known as gray water^[13]
Integrated Pest Management techniques for pest control
Creating and enhancing wildlife habitat in urban environments^[14]
Energy-efficient garden design in the form of proper placement and selection of shade trees and creation of wind breaks ^[15]^[16]
Permeable paving materials to reduce stormwater run-off and allow rain water to infiltrate into the ground and replenish groundwater rather than run into surface water^[17]^[18]
Use of sustainably harvested wood, composite wood products for decking and other garden uses, as well as use of plastic lumber^[19]
Recycling of products, such as glass, rubber from tires and other materials to create landscape products such as paving stones, mulch and other materials^[20]
Soil management techniques, including composting kitchen and yard wastes, to maintain and enhance healthy soil that supports a diversity of soil life
Integration and adoption of renewable energy, including solar-powered lighting^[21]
Development of lawn alternatives^[22] such as xeriscaping,^[23] floral lawns,^[24] and meadows.^[25]

Proper design

One step to garden design is to do a "sustainability audit". This is similar to a landscape site analysis that is typically performed by landscape designers at the beginning of the design process. Factors such as lot size, house size, local covenants and budgets should be considered. The steps to design include a base plan, site inventory and analysis, construction documents, implementation and maintenance.^[2] Of great importance is considerations related to the growing conditions of the site. These include orientation to the sun, soil type, wind flow, slopes, shade and climate, the goal of reducing irrigation and use of toxic substances, and requires proper plant selection for the specific site.

Sustainable landscaping is not only important because it saves money, it also limits the human impact on the surrounding ecosystem. However, planting species not native to the landscape may introduce invasive plant species as well as new wildlife that was not in the ecosystem before. Altering the ecosystem is a major problem and meeting with an expert with experience with the wildlife and agriculture in the area will help avoid this.^[26]

Irrigation

Mulch may be used to reduce water loss due to evaporation, reduce weeds, minimize erosion, dust and mud problems. Mulch can also add nutrients to the soil when it decomposes. However, mulch is most often used for weed suppression. Overuse of mulch can result in harm to the selected plantings. Care must be taken in the source of the mulch, for instance, black walnut trees result in a toxic mulch product. Grasscycling turf areas (using mulching mowers that leave grass clippings on the lawn) will also decrease the amount of fertilizer needed, reduce landfill waste and reduce costs of disposal.^[27]

A common recommendation is to add 2-4 inches of mulch in flower beds and under trees away from the trunk. Mulch should be applied under trees to the dripline (extension of the branches) in lieu of flowers, hostas, turf or other plants that are often planted there. This practice of planting under trees is detrimental to tree roots, especially when such plants are irrigated to an excessive level that harms the tree. One must be careful not to apply mulch to the bark of the tree. It can result in smothering, mould and insect depredation.

The practice of xeriscaping or water-wise gardening suggests that placing plants with similar water demands together will save time and low-water or drought-tolerant plants would be a smart initial consideration.

A homeowner may consider consulting an accredited irrigation technician/auditor and obtain a water audit of current systems. Drip or sub-surface irrigation may be useful. Using evapotranspiration controllers, soil sensors and refined control panels will reduce water loss. Irrigation heads may need readjustment to avoid sprinkling on sidewalks or streets. Business owners may consider developing watering schedules based on historical or actual weather data and soil probes to monitor soil moisture prior to watering.^[2]

Building materials

When deciding what kind of building materials to put on a site it is important to recycle as often as possible, such as for example by reusing old bricks.

It is also important to be careful about what materials you use, especially if you plan to grow food crops. Old telephone poles and railroad ties have usually been treated with a toxic substance called creosote that can leach into the soils.

Sustainably harvested lumber is available, in which ecological, economic and social factors are integrated into the management of trees used for lumber.^[28]
