Rooftop gardening at the office

I think it must be the sunshine and the changing of the clocks. I've been feeling all nature-girl this week. I've started what I hope will become a vegetable and herb garden on the rooftop balcony of my building at work. I remember when I first started there two years ago I noticed the large concrete pots out there full of dead trees and weeds. I think it might have been winter and so I wasn't entirely sure if they were dead or just deciduous and didn't really know who to speak to about it at the time. Now two years later I've take things into my own hands and I've started weeding out the dead stuff and the weeds. It looks like perfectly good soil (although I wouldn't really know) but I have found earthworms and millipede insects in there so that's a good sign of fertility, hopefully. A few of my colleagues are up for being involved, so I'm hoping that next week some cuttings and seeds will appear from their generous homes. I'll have to remember to take my camera next week to document the progress of this exciting project. For now you'll just have to make do with this photo of the building.

The balcony is along the left side of the roof in this picture and wraps around two-fifths of the front from the top left corner. It's north-facing, so perfect for things that need lots of sun.
There are 6 or 7 concrete pots of about 1 x 1 metre (3 or 4 ft square) and 50cm (1.5 ft) high spread out along the balcony and probably about 10 more smaller round pots, most of which have geraniums in them. Geraniums apparently are very tolerant of dry conditions because although they've become tall and straggly they're fairly healthy despite never being watered in their pots and surviving on the rain alone, which is pretty good for a potted plant.

I'm also considering setting up a worm farm out there as the balcony is right near the department kitchen and all the organic waste currently goes to landfill, which really isn't right, especially for an environmental science department! I happen to have a plastic worm farm box set sitting in the garage that I got from one of my favourite places in Canberra - Aussie Junk at Mitchell. I think it cost me $5 but I've not put it into action yet, as the compost bin in our yard looks after our kitchen scraps at home. Anyway, here's a pic of the worm farm and a pic of the papers I got from a vermiculture information session I went to once at the Canberra Environment Centre.




I'm still a bit unsure about how it will work and a little hesitant knowing that if it doesn' t work, I will have killed living things, but I think it's worth a go. My mum has had a successful worm farm for quite some time. Hmm...think I will give her a ring now to double check what I need to get started. And then I might read a bit more of my "Food Not Lawns" book that just makes me want to move to the greeny haven of certain parts of Oregon.
