Frost: Our diverse marsh, six months later

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.

 

Ready for a review?

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.

 

Here’s what we put in our garden – so far!!!

Carlin Springs ES: Bog Expansion and Composting

November 9th, 2012

The bog is happy and healthy — and providing an oasis for the turtles! Students dig up more turf grass so that we can expand the area of our created wetland.

Carlin grub! Learning respect for all living organisms and debunking the myths that cause all those squeamish squeals associated with crawly critters — is at the heart of what we do!

Students planting woodland sedge around the hibernaculum

Learning about the magnificent marvels of the decomposing world through a primer on vermicomposting! Students harvest red wiggler worms from an older composting bin and create a new, roomier home for them. The richly fertile worm castings will provide new life and nutrients for our gardens.

Carlin Springs ES: Creating a Turtle Hibernaculum (Part 2)

November 2, 2012

Students amend the existing soil with rich, composted leaf mulch.

Students haul amended soil over to the hibernaculum area.

Rich soil is piled over hollowed logs so that there are numerous cavities for the turtles to easily dig themselves safely into the earth for the coming winter.

Ready for burrowing!

While we’re at it — a brush pile to provide shelter for birds and habitat for invertebrates.

Teamwork! An old log becomes a makeshift turtle ladder.

Swamp milkweed in the bog goes to seed.

Wind dispersal — students help to spread milkweed seeds.
