Why we use the edge• Productivity increases at the edge because resources from all
present systems can be utilised.
• Edges define areas. Elements, sectors and zones become more manageable with an edge.
• Human brains like an edge. Edges provide order and a system within which we can work and play.
• Edges are a symbolic language and a place where humans and plants can interface and meet.
• Edges allow access for planting, mulching, watering and harvesting.
Application and Individuality• Observe nature and harness this amazing resource by
using it to design ecological systems that are productive in your back/front yard and community.
• Apply design to express your individuality; character, location, time, physical ability and include yourself in the observation of nature. HOW?
• Permaculture designers are free to design creatively.• Be careful not to replace a conventional dogma with an
unconventional dogma.• Small scale systems allow greater pattern complexity and
edge. Larger systems can be simplified to reduce work.
Using Air Space• Designing in 3 dimensions. For example; creating forest
garden edges in the vertical as well as horizontal that mimic a woodland edge.
• Designing a raised bed with attention to the vertical as well as the horizontal thereby maximising edge - as nature does. This creates more productive, fertile systems. This could include;
• The use of structures and supports• Under planting of herbs• Vines draping over the edge and trained to grow around the
raised bed• More ideas anyone?
An Oak Leaf• Patterns in Nature
More Edge!• A Car Park
• This could be used to
produce food. This
design application could
change the city scape and
environment.
What benefits can you
think of? Environmental
and social.
And More Edge
• On the edge of a river in a city. Silt brings nutrients, reflected light from the river and the heat bank wall.
Use of the edge
within the edge as a small
windbreak and to stop soil falling in the river.
Edges Provide Interest• Some space can’t be
used but the edge can!
Costa and the verge.
Using the edge between the
road and the house to grow
productive crops.
More about edges…
• Edges can be used as a barrier against pests, weeds that are not wanted and predators.
• Pests – Plants on the edge that repel pests and encourage beneficial bugs.
• Predators – A fence protecting livestock and fowl from foxes. Dog wee on the edge is an effective deterrent.
• Edges can improve access to plants particularly regularly used plants.
Innovative Edges• Mobile Decoy of nasturtiums. This is a trap crop, to
encourage unwanted bugs like aphids, onto the trolley and away from the
crop/plant.
• This is a mobile edge!
