Over the past two days Elden Sandy leveled the bottom of the hole for the garden bed, installed the plastic sheet in the hole with help from Rick Austinson, cut and installed the cement board for the floor of the garden bed, then stacked the concrete block on the cement board. As a result, the last bed to be constructed is now ready to be filled with dirt and compost. [The day following this post students filled the last garden bed with compost and dirt.]
