I definitely want herbs. I definitely want tomatoes. I know there's going to be some big containers with some nice, happy dirt. Aside from that, I'm clueless. Ironically, my family has owned a company that has sold horticultural products to garden centers for over 20 years, so...it seems like some knowledge by osmosis should kick in. But there's something that feels so different about an urban rooftop environment at the 41st North latitude. It's not a greenhouse in the Rocky Mountains.
What I have learned from the past two summers on the roof is that it's exposed to blazing hot sun and some occasionally fierce wind over the relatively short Chicago growing season. I need hearty stuff that can take full sun.
All forms of advice are welcome. So far, I'm starting to study up with the Mayor's green roof guide. I can just picture him sleeping with a copy of it under his pillow, dreams of radishes dancing in his sweaty head.
