Warranties on plantings often seem reasonable. Until they aren’t.

FROM THE FEBRUARY 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

Most landscape architects are familiar with specifications about plant warranties. We often apply them without much thought because many consider it to be an industry standard practice. A typical plant warranty, usually lasting one or two years, requires the contractor to replace plantings that have died or appear to show unsatisfactory growth.

The commonplace nature of this situation belies its complexity, an adjacency that represents an interface between two systems with antithetical requirements. In this case, the edge between pavement and planting bed is an area where an engineered structural system abuts a living horticultural system. Successful design solutions frequently require landscape architects to reconcile competing interests, but it is not always easy, given the demands of a project. In SiteWorks’s practice, we see the pavement–planting edge as a challenge for both designers and contractors alike. The edge merits special attention with regard to how we design and document the condition, how it’s built, and how its thoughtful assembly can benefit long-term performance.

The Basics
Let’s start with what a successful pavement system needs. The structural support of a pavement relies on (more…)
