Adopt a Mediterranean Plant: What we’re already learning

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.

The little plant that could

We spotted this plant back in May, appearing seemingly out of thin air and looking surprisingly un-weedy for being a volunteer. Since then, it has grown without irrigation for months, and has stayed remarkably green too, not once showing signs of drought stress. The thing is, we have no idea what this plant is. We are waiting for it to bloom to have a better clue of what it might be. In the meantime, we’ll marvel at its toughness and its ability to plant itself in horrendously compacted soil and thrive all summer long on basically zero water.

Once again, plants growing and thriving irrigation-free are all around us. We just have to open our eyes and look.
