Maintenance
Ongoing maintenance has included removal of invasive plants that can cause problems to the building envelope and application of beneficial microorganisms and nutrients with compost extract.
Challenges / Solutions
Working with site to find best practices for installation to ensure long-term health of plants. Proper sequencing with general contractor to ensure that plants were not walked on.
