My school, the John Witherspoon Middle School (JW), has a Memorial Garden tucked into a wonderful small niche in the front of the school. It is a sort of “secret garden,” bounded on one side by a school corridor with a wall of windows. This allows humans a view inside without needing to encroach on the garden’s privacy. This makes it a perfect place to try to create a functional—and visible–ecosystem where plants will feed insects and other animals, where insects will pollinate plants and raise young, where some insects will become food for birds, and where birds and other animals will find shelter, food and water.
We had plenty of native plants–I still had part of a donation to the Princeton Schools from Pinelands Nursery, arranged through sponsorship from the Mercer County Soil Conservation District. Mark Eastburn, the Science Teacher from the Riverside School, had native plants through grant funding from the American Society of Plant Biologists (ASPB). Mark’s plants included some carnivorous (insect eating) plants, specifically Venus fly traps, sundews, and pitcher plants.
The garden already had some traditional decorative landscape shrubs, including azaleas, crape myrtle and those green bushes that prune so well into geometric shapes but whose names I never learn. We decided to retain the existing shrubs as a layer in a multi-layer landscape. Under and around the shrubs we would add the herbaceous native plants including sedges, monarda, goldenrod, columbines, and many others to provide shelter to flowers and animals as well as soil health promoting ground cover.
The whole project was a team effort not only by Mark and myself, but of the whole Princeton school community. A lot of the effort was enthusiastically provided by students from Nyrie Janho’s Food Science and Wellness Classes, and by the school’s two Robotics Club teams, the JW Hornets and the Techno Tigers. Students helped clear the English ivy and other invasive weeds that were overrunning the garden. Mr. Eastburn and his students sunk five tubs into the ground for the carnivorous plants; the tubs will be watered only by rain water, which will help the plants retain the moisture they require to thrive.
Both of the Robotics Club teams are preparing for a competition that requires them to not only build Lego robots but to plan and carry out a community service program. The Techno Tigers, whose project involves encouraging birds to take up residence at JW, raised funds for a bird house and bird bath. The JW Hornets are working on a project to help bees, which are increasingly endangered in the modern American landscape, and will be adding elements to the garden for this purpose.
Compost and mulch were supplied by Princeton Public Schools Grounds Foreman Tony Diaforl and his crew from the ecological facility that Princeton shares with Lawrence Township. We applied the compost as an initial top dressing to supply organic matter and some nutrients from the surface down, just as it happens in natural systems. The top dressing of compost will work with the mulch to discourage weed seeds from growing by denying them the sunlight that they require to germinate. We mixed the donated mulch with leaves collected from the school lawns for the second layer over the compost. This combined mulch layer will provide not only protection for the soil, reducing oxidation of carbon and soil nutrients, but cover for small critters including insects.
John Witherspoon Middle School Teacher Kelly Riely has arranged for some of the members of her Do Something Club to water the new native plants once a week until it gets colder.
The project could not have been done without the support of Princeton Public School District personnel, including Science Supervisor Edward Cohen and John Witherspoon Middle School Principal Jason Burr.
The garden is still very much a work in progress, as we wait to see both how well our new introduced communities of plants and the ones already there function together. In the spring, we will add additional plants to fill any holes and to replace any plants that don’t make it. We will continue to recruit members of the JW and the larger Princeton communities to help with maintenance as a form of stewarding some of the ground that stewards us.
