Summer seems to have ended but our rooftop garden is now ready for winter.
We harvested lots of onions and carrots.
As well as many red and green tomatoes.
Tomatoes need to be harvested, even if still green. If left on the plant during cool temperatures and rain they will develop blight and turn black instead of red. Wrap your green tomatoes in newspaper and store them in a cool dark place until they ripen.
Tomato plants were then removed and put in our yard waste bins for composting (blight may spread in a cold composter, but in Vancouver yard waste is mechanically composted using heat).
We also planted some more fall crops (many winter crops should be planted in July or August, but due to extreme heat on our roof in these months not many seedlings were started successfully)
We planted overwintering broccoli starts, kale seeds and garlic after amending the soil with compost from our worm bin composter.
Garlic is grown by separating the cloves of the garlic bulb and planting pointy-end up roughly 4 inches deep in the soil. Each clove will form a new bulb. We simply bought local organic Red Russian garlic from a nearby grocer.
Happy autumn!

Holy Corn and Potatoes Batman
This weekend was the first rain we've had in Vancouver in weeks but we still had a great turnout at The Cambie Square Garden on Sunday. Noone even minded the rain and worked away together to harvest quite the bounty. We harvested lots of potatoes and corn and some really beautiful carrots too.

June 1st Gardens Update
Spring is in full force and all the hard work and planning from the previous months is truly paying off.
School GardensStudents from a nearby school recently brought seedlings they started in their classroom to plant on our rooftop container garden.
Rooftop Garden
Fava beans are flowering on the roof!Lettuce is harvestable!
Tomato seedlings are in! (Started in Carole's backyard greenhouse)
Cambie Square Communal GardenNew lovely signage care of Jodi Mayne!
We've got bees! Mason bees have moved in to our mason condo (thanks EYA!) you can see they've filled the holes with mud.

SPEC in April
It's a beautiful yet chilly Friday in April. With the sun shinning brightly it's a great day to take a few photos of our Rooftop Container Garden to share.
We will be starting regular bi-monthly Rooftop work days starting this Friday from 9 to 11am. Come start seedlings with us!
Peas are growing! (Will be transplanted to a larger container)
Anise Hyssop and a Calendula flower
Colourful flowers attract pollinators
Carole brought us these lovely broccoli starts!

New Research Project at SPEC!!

There are new things happening at SPEC!
on crop yields.
We have recently set up our experiment on SPEC's rooftop and I will be documenting our experience on this blog! We invite you to follow our progress and learn with us along the way.
Our experiment is designed like this: using a common potting soil (approx. 70% peat and 30% perlite) as our medium we have chosen three different soil amendments to grow our crops. This gives us four soil treatments in total.
#1: potting soil
#2: potting soil + Gaia Green 4-4-4
#3: potting soil + Sea Soil
#4: potting soil + Miracle Grow 24-8-16
We have planted the following four crops individually into each of the four soil treatments.
#1: Lettuce ( C.V Darkeness)
#2: Radish (C.V Altaglobe)
#3: Kale (C.V Red Russian)
#4: Pea (C.V Little Marvel).
Because we have 4 soil types and 4 crops we are provided with 16 soil/crop combinations. We are replicating each combination 15 times so we have a total of 240 containers on the roof!
We will document crop growth and measure the yields after harvest to determine what effect soil amendment choice has on yields.
Our hope is to obtain some interesting results that we can share with growers and improve the success of urban agriculture right here in our backyards (or rooftops for that matter!). Feel free to stop by SPEC and check out the garden or to post questions or comments for us to answer!
Happy Growing... Kate
