This is the start of a new era. As of today I'm planning on noting ideas on sustainable sensory gardens I'm working on, or have worked on. I'd like to share ideas and hopefully gain some from you too.
First up: Materials.
For any garden to be sustainable, it must by definition "meet the needs of the
present generation without comprising the ability of future generations to meet their
needs”.
Paths are a significant feature within a sensory garden. To be sustainable, choose materials such as locally sourced wood. Recycled sleepers, bamboo poles and bark chippings,are low carbon solutions for paths. They require little processing or transportation. Treated softwood decking has the benefit of captured carbon within the wood fibre but takes more energy that the other options to process and trasnport to site.
Going up the carbon scale, locally sourced gravel requires energy for extraction, crushing and processing from quarry to site. It lasts as long as the bark choppings before needing to be topped up.
Recycled aggregates offer a choice of materials. They use energy to produce, but as a use for otherwise waste products offer other benefits.
Next time, water
