These white buckets may look familiar. They're the same recycled bucket planters used by Art and Heidi on their rooftop garden in Wicker Park, Chicago.
There's one significant difference however. These are not sub-irrigated planters. Laura the owner of this New York City rooftop garden installed a drip system rather than sub-irrigate.
What's the difference? Who knows but it's worth a comparative study. For sure, sub-irrigation and drip irrigation will out perform manual overhead watering.
The problem of course is that our institutions have failed us. Individuals like Laura, Bruce and Heidi to name a few are doing the heavy lifting both literally and figuratively.
Our horticultural, gardening and botanical institutions are stuck in an outdated farming paradigm that's inappropriate in densely populated cities. .
At a time when food production, water shortages and ominous predictions about the future dominate the news, our institutions practice primitive methods of urban agriculture that waste water, resources and time along with taxpayer dollars.
Remember that the majority of these institutions are funded with public or donated money. We should expect a lot more than we are getting.
