The Eco-roof on the Shed

After months of work in the Spring on our home-made shed,

and a then summer of more play than work...
...we finally were ready to buy a bunch of seedum and grasses
for our long-awaited eco-roof! After many weekends of roof preparation
(3/4 in plywood, plastic barrier, 2x4 edging, drainage barrier)...

...it was finally time for the fun part: planting!
We started unloading the lava rock and
sandy loam while it was still light,
but were determined to finish in the dark
while we still had Geoff's dad to help us.

The first layer was about an inch of lava rock,
then on top of that, a couple inches of perlite
mixed with sandy loam and compost.

Tamara was the official perlite mixer...
unfortunately, we didn't read until about half way
through the process that we should
avoid creating perlite dust. Ooops!

And then, between sun and rain showers,
we had it all planted with lots of room for growth!
Over time, the seedum and plants will spread and grow...
...to fill in the dirt in between, and ultimately...

...look like this eco-roof at People's in SE Portland.
