The first in an ongoing series of videos on the wide wild world of landscapes and how you can be a part of and engage with landscapes and the natural world in the ways that are meaningful to you. This video looks at how to go from a lawn to a garden and manage what can suddenly seem like an overwhelming number of choices and details. “A landscape comedy,” one person described it as. I’ll take it. Happy viewing.
It’s hard to say what you first notice when you see the irrigation-free landscape now after six years of being in the ground. Perhaps that everything looks huge and full and not at all tired or half-dead or all the things people were worried might happen when we proposed the idea seven years ago. The little bluestems (Schizachyrium scoparium) have self-sown with abandon, as have the pale purple coneflowers (Echinacea pallida) and butterfly weed (Asclepias tuberosa). The Golden Spirit smokebush (Continus coggygria ‘Golden Spirit’) looks almost otherworldly in its stature and form – no doubt loving the gravelly, crummy soil we planted it in. Some extremely tall perennials have also appeared in the landscape, and, for the life of us, we can’t figure out what they are, but once they’ve bloomed the mystery should be solved. The pathways are less perceptible than they were before – in part because of how big the grasses have gotten, but also because they need a good weeding (we learned early on how much certain self-sowing plants loved the gravel as a growing medium). But all in all, we think most would call the landscape a success if they saw it – and the bees and butterflies think so too, as they have very much found an ideal foraging spot within it. And how exciting it’s been to see the landscape take on a life of its own since it isn’t tethered to an irrigation system. So maybe that’s what you sense most when you see it now: a freedom and exuberance that can only be found within a landscape that is given a little license to do what it wants.
What’s been interesting to observe already with the Adopt-a-Mediterranean Plant Project is how the water needs of the grasses are really mirroring what we learned with the grasses in the first irrigation-free landscape we ever did. Namely, the grasses seem to always need two waterings spaced about a week apart, and then perhaps a third a couple weeks later, and then they reach a point where they can comfortably be on their own. As their adaptation to drought lies primarily in their roots, and thus these waterings are helping the plants send the roots deep into the soil, we shouldn’t be surprised, but, well, this work is always surprising, as you see first-hand just how little water so many of these plants actually need, even in drier mediterranean climates.
Stay tuned for more updates.
When we say we do irrigation-free landscapes, the response we so often get is that that is impossible. Well, however cliched and trite, the adage “seeing is believing” never fails to ring true. We know irrigation-free is possible because we have done it, and we also see plants growing irrigation-free all around us every day. So that you too can see this reality in action, we’ve launched a new citizen-science-based project in which we give you a plant from a mediterranean climate region of the world and then you monitor its water needs over the course of the year. At the end of the year, we will have a gathering to share what we have learned. Additionally, and more importantly, participants will ultimately become their own irrigation-free experts, and we will be able to create a set of meaningful data on the water needs of plants from summer-dry climates. These data can then be applied to the creation of new irrigation-free landscapes across California and the country at large. To learn more, click HERE.
We will be speaking on our work on irrigation-free landscapes at the annual PG&E Water Conservation Showcase in San Francisco on March 21. Specifically, we will be co-leading an interactive workshop on water conservation in residential landscape design with fellow landscape designer Kelly Marshall and Outreach Coordinator for the California Native Plant Society Kristen Wernick. All are welcome to attend. Sign up here.
