From the Farm: Permanent Raised Beds at ECHO North America

Utilizing raised beds has been a critical component to a successful seed production program for our Seed Bank at ECHO North America. For years we have followed the industry standard practice of temporary raised beds covered with plastic mulch. With no real use for the plastic after the year’s production cycle, we would begrudgingly discard the plastic in the garbage. The effort, expense, tillage, and waste in re-raising beds each year started us on a quest to find a more appropriate solution: is there a better option out there?

To answer this question, we are testing various designs for permanent raised beds. For the first round of testing, we have built beds out of six different materials: bamboo, recycled metal roofing, wood, concrete block, earthbag, and ferrocement. While initial investment cost is a major factor, the expected useful life, maintenance costs, usable growing area, and productivity of each bed will be important considerations.

After an evaluation period, we hope to convert much of our Seed Bank production into permanent raised beds. While we don’t expect one clear winner for all contexts, we hope some of the lessons we are learning in this process might help others determine what the best option might be for them. Stay tuned for more updates along the way!
