Under Construction

You may have noticed the massive amounts of construction going on in Parkallen this summer. Park Paving Crews and the City of Edmonton are re-constructing roads all over the neighbourhood and Phase 1 of re-development in Ellingson Park (spray deck construction) is well underway.

We’ve been busy too.

If you could see behind the road work in this photo, you’d see a very gentle, much lower-tech kind of construction going on: the soil for the Parkallen Community Garden building itself under layers of mulch.

To create a loamy and productive Community Garden in Parkallen we are deploying a technique called lasagne gardening. You layer some water, some mulch, some straw, some cardboard, some more mulch, some more water, and a pinch of mycorrhizal fungi. Then wait for the snow to come and go and next voila! Presto! Next Spring we’ll have rich, cultivable earth where before there was just a dandelion-strewn stretch of grass.

Here’s how we did it:

First hundreds of volunteer-hours went into securing funding and finalizing the plans for this pea-pod shaped garden:


Thanks City of Edmonton, Dustin Bajer, The Parkallen Community League, The Parkallen Diggers, The Parkallen Re-development Committee and Robert Kirchner for your vision and your hard work.

Construction began with flagging the contours of the proposed garden on the site. Then we started digging drainage/irrigation swales. The swales utilize the natural slope of the land to gather precious rainwater towards the garden.

Digging through sod is tremendously hard work.

But dig we did.

Next we assembled the ingredients for our lasagne garden — a no-till method of converting sod into soil.

Cardboard — thank-you City of Edmonton Waste Management for permission to gather it from depots
Straw — thank-you Barry and Steve and the rest of the staff at the UofA Research Centre (South Campus farm) for donating and delivering the bale
Compost — thanks Kevin
Mulch — thank-you Robert

Large, plain pieces of cardboard like these appliance boxes here are best for lasagne gardening.

It is important that the ground covered with a layer of cardboard (to kill the grass underneath) is wet (to increase the bio-activity) so you can either hose it down or, even better, cardboard mulch on a rainy day and hose it down, like we did. We were lucky to have access to the fire hose used to flood the adjacent hockey rink. Thank-you, Parkallen Community.

The pieces should overlap at least a few inches.

We covered the entire area over a number of sessions. The next step was to sprinkle a very thin layer of compost on top of that (again, to increase bio-activity) and then to pile about a foot of straw on top of the cardboard.

The straw was hosed down and then a thicker layer of compost was spread over top of that.

A lot of local muscle and many wheelbarrow trips went into this endeavor.

Our volunteers were undaunted.

Then we filled in the irrigation swales and the centre pathway with bark mulch.

Robert sprinkled some barley seeds on top of everything to make sure there would be enough roots in place to hold everything down. The grass (from seeds in the straw) and the barley sprouts won’t have time to go to seed and can replace bark mulch (which would be hard to get out of the soil next spring).

Now, against a backdrop of high-tech machinery we’re doing a radically low-tech thing: we’re putting down our shovels and waiting for the soil to build itself.

You know that old joke — in Alberta there are two seasons: winter and construction.

Happy Construction from the Parkallen Diggers.

We’re Digging it in June 2011

The Parkallen Community Garden received official approval by the City of Edmonton on June 3, 2011. So we’re digging it this spring!

Future Site of the Parkallen Community Garden at 65th Ave in Ellingson Park

Well, we’re not actually digging it per se, as we’ll be using a no-till strategy to build the soil in our beautiful and innovative pea-pod garden. More on this to come….

Here are our final plans:

Thanks to Gilbert Catabay, landscape architect with the City of Edmonton; Dustin Bajer, master gardener and permaculture specialist; as well as all the people who attended the Parkallen Community Garden Design Charette on March 5, 2011 at the Parkallen Community League. What an exciting design!

Parkallen Pea Pod Garden Plan

The slight diagonal orientation of the garden follows the contour of the land, allowing for more even flow of rainwater into the garden as it runs downhill from the northeast. Community fruit trees and compost bins will be along the rink side of the garden. The garden will use run-off from the rink surface as well as rain water gathered in barrels.

The gravel pad (grey area on the right) will be accessible off the sidewalk on 65th Ave. The garden will run along the length of the hockey rink at Ellingson park. It will be built in phases, (right to left) and not all at once. The plan indicates 36 beds which occupy an area of roughly 400 square meters. Raised beds for gardeners with reduced mobility are also included in the plan.

The light brown lines through the garden are mulched pathways. It is designed using a keyhole gardening concept which means that the amount of cultivable land is maximized by making every square foot of garden accessible by the mulched keyhole pathways, but the amount of total area dedicated to pathways is minimized.

The Parkallen Community Garden is one phase of the Parkallen Park Re-Development Plan:

F.Y.I. this is not us:

This is a City of Edmonton construction laydown area for the road re-construction crews who will be replacing roads throughout Parkallen this summer.
