- March to April 20202 Mar 2020Follow up soil testing confirm the sunflower crop sufficiently improved soil health. We will now start designing the Cruikshank Street Reserve landscaping.
- February to March 20202 Feb 2020The sunflowers were harvested.
- January to February 20202 Jan 2020The sunflowers began flowering. We anticipated the site would attract some attention and monitored any impacts of this on surrounding residents.
- August to November 20191 Aug 2019Site clean-up, cultivation and sowing of sunflower seeds. The area was fenced to discourage pedestrians from trampling the site. The newly sewn seeds were watered regularly by Council contractors.
Why are we doing this?
The sunflower is one of many plants that are known to remove, transfer, stabilise, and destroy contaminants in soil. This process is called phytoremediation.
We planted sunflowers on Cruikshank Reserve to prepare the soil for new trees and landscaping. Site preparation works began in August 2019 so that the site was ready for the seeding of sunflowers in November.
Compared to other soil rehabilitation methods, planting sunflowers is a clean, cost-effective and environmentally friendly way to improve soil health.
