Students mix composted leaf mulch with excavated clay soil.
A student begins the Carex grayi planting.
Carex grayi has an ornamental seed head. It thrives in both sun and shade, in rain gardens and around storm drains.
A team of girls join in and the Carex planting is almost done.
Here’s the first summer’s growth of Hibiscus. It really loves the rich, moist soil surrounding the drain.
The native switch grass, Panicum virgatum ‘Shenandoah’ has tripled in size since its April planting. A great plant for stormwater management.
By the end of the summer, the plants have matured enough to begin their hard work of filtering and holding back stormwater.

Step 1: Find a drain.
Step 2: Remove turf grass adjacent to the drain to the size you want your garden to be.
Step 3: Excavate existing soil any where from 6 – 12″ (depending on your energy level – deep is good!)
Step 4: Mix excavated soil with composted leaf mulch; about 50-50.
Step 5: Fill in the excavated area with the amended soil.
Step 6: Plant tough, native plants that can tolerate both wet and dry conditions.
Step 7: Topdress with leaf mulch.
