I’m pleased to announce that the next phase of Hanging Garden R&D is underway. Starting with a 1-1-1 mix of sand, homemade compost and potting soil, I’ve seeded all five levels of a Hanging Garden now swinging from the rafters at the Sugar Shack with small herbs that will help prepare its soil for later planting, attract birds and beneficial, predatory insects like ladybugs, long-term test the Hanging Garden’s performance in outdoor conditions and offer the intentional community here another baby step toward urban economic liberation.
Part of the fun is getting to experiment with five separate “test tubes” if you will. The bottom three levels got dusted with seeds of the yarrow plant, which according to legend was carried into battle by Achilles because of its effectiveness in treating battle wounds, and whose tendency to accumulate minerals means rich soil will be left in its wake. The fourth level up is planted with both yarrow and echinacea purpea seeds to get an idea of how the two behave together. The top level is seeded with echinacea alone, and echinacea is the go-to plant for easing a cold out of your body (something the house could use right about now).
For both herbs the winning planting formula appears to include spreading the seeds no more than ¼ inch deep. The yarrow seeds are little bigger than fine grains of sand and get spread liberally. The larger echinacea seeds get dropped individually about 2 inches apart. Then on all levels, I overlaid some exhausted coffee grinds from the house coffee maker.
The setup will get lots of sun on the rooftop, just like these plants love. It is winter here of course, but it is Southern California and these plants which would get planted later in the spring further north can take the couple of frosts we might get this season. If all goes well, we should start to see little green leaves popping up in about a week or so.
And this is a great opportunity to explore what the Hanging Garden can do best. For while we grow these herbs here, as other installs go up, Hanging Garden clients can begin to share notes – I hope to have a forum for this on Vertecology as more installs go up and things come together.
And finally, a bit of cross pollination – it’s great to be watering the Hanging Garden with water from the rain harvesting system in the downstairs garden. Already watering the Hanging Garden on the rooftop, I’ve taken on watering the whole roof garden; prior to building the water harvesting system, I knew simply that our rooftop garden needed water. The water messily came out of a hose when I turned on the spigot, and that’s about all I knew.
I always felt a pinge of guilt in watering the American Way, having no idea of how much water I was actually using, and only knowing that the water was coming from places like Mono Lake and the Sacramento Delta. By watering with buckets from the harvesting system, I’ve learned that the rooftop garden requires about four gallons per day in the winter time. Sure the watering is a bit more laborious but the information gained while exercising – climbing stairs with bucket in hand, has named the unnamed and means that I can now realistically design for how much water a design-build-permaculture install will actually need and yield.
Thank you Norma Bonilla for the soil mix formula and Baza Novic for the seeds and planting direction. I’ll keep y’all posted, and of course I welcome feedback. Thanks!
