At this year’s Organic Conference in Guelph, Ontario, Zora introduced me to a fabulous container for growing vegetables on roof top gardens. The product is from Alternatives, an international cooperative network, in Montreal. The special recycling box design uses irrigation by capillary which reduces the amount of watering required. The design includes the following: a filling top (for watering), submerged soil mixture column, water reservoir and a false bottom (which you plant on top of). This method was successfully experimented on the Roof Top Garden at the Big Carrot health foods store. A great idea, just in time to get us excited about the upcoming growing season.
