Goals and Strategies

Soils

• Create or maintain a functioning soil ecosystem.

• Use a soil test to determine existing nutrient levels on site.

• Provide nutrients based on soil test recommendations.

• Use locally-generated compost as needed to improve soil structure and reduce runoff.

• Limit soil compaction using light-impact equipment and being aware of soil moisture.

• Use pesticides only when benefits outweigh environmental risk.

Figure 8: Soil Profile

Hydrology

Utilize strategies to promote infiltration and maintain integrity of the watershed.

• Select plants to fit existing soil moisture conditions.

• Provide irrigation only when required for plant establishment or management during extended drought.

• Use captured and treated rainwater, grey-water, and wastewater when irrigation is necessary.

• Reduce or limit impervious surfaces to improve water infiltration.

• Reduce storm water discharge by installing gardens to slow water movement and encourage infiltration

(rain gardens, green roofs) rather than relying on storm water collection and removal from the site.

• Prevent sediment runoff with appropriate construction practices and maximized plant cover.

Vegetation

• Develop plant communities that serve as a foundation for a healthy ecosystem.

• Reduce dependence on resource-intensive features, such as manicured lawns thereby reducing extra inputs of

chemicals, energy and time.

Wood - Redwood salvaged from other structures is a sustainable choice. Treated landscape lumber is readily

available and, if maintained properly, can last 15-20 years.

Plastic Lumber - They all resist rot and insects and can substitute for preservative-treated wood.

Human Wellness

• Use the landscape to reconnect people to nature.

• Create spaces that are inviting and useful.

• Value the human component of landscapes and social benefits gained by interaction with gardens and natural

spaces.

Sustainable Garden Practices

A more-sustainable garden has fewer inputs and fewer outputs than a less-sustainable garden.

• Make compost unceasingly. Making compost should be part of the routine in every garden, even if it is no larger

than a window box. Items which cannot be composted domestically (e.g. wood) should be composted

municipally.

• Wood material can also be burned.

• Use home-made composts in place of artificial fertilizers and other organic additives.

• Practice rainwater harvesting. Water should be collected from roofs and pavements, stored in gardens and

infiltrated into the soil, slowly.

• Use physical and biological pest controls instead of chemicals.

• Return to nineteenth century methods of soil warming, based on the use of compost.

• Use a hand-powered grass-cutter instead of a fossil-fuel mower. This will also save you the cost of an exercise

machine.

• Use solar power for garden lighting and garden pumps

• Use lime mortar (not cement mortar) for garden construction, so that hard landscape materials can be re-cycled.

CONCLUSIONS

Landscapes are responsive, re-generative and can contribute to the active and healthy development of the

environment and its communities. They create values through significant economic, social and environmental benefits.

This can be achieved by Short term goal - Composting locally grown crops and kitchen waste and returning it

back to the garden increases the organic matter in the garden while recycling nutrients within the landscape and Long term

goal - Create a more self-sustaining garden

It is in the hands of architects, planners, engineers, horticulturalists, and others work in interdisciplinary teams to

create innovative models that outline a path to make the maintenance and practice of landscapes sustainable for the future.
