Do you know Hugelkultur? Pronounced "hoo-gul culture," this method of raised beds uses logs and wood material underneath the soil as a moisture collector to help with watering efficiency, recycle materials in the garden, and add beneficial fungus and microrganisms.
At Cedaroak, our woods and grounds are rich with right ingredients for a Hugel bed. During our Fourth Grade Work party, we sent the kids on a scavenger hunt to find logs and sticks to construct our bed. Our crew dug a 3 foot-wide trench in the shape of two L's, lined the bottom with logs, layered deadfall branches and twigs, filled the space with straw, then covered the whole thing with soil.
