Seed Power

By Lauren Lewis One of the defining characteristics of plants is unfortunately a limitation: their inability to move around. They have to reach out from where they are to find water and mates, or let those resources come to them, and they’re certainly disadvantaged when it comes to escaping danger (although many have evolved ingenious compensating strategies). Because of this limitation, the seed, the…

Gardens for the protection of the SF Bay

By Lauren Lewis The winter rainy season is a happy time for our gardens, and a less happy time for the San Francisco Bay. That’s because heavy rains, which typically happen a handful of times each winter, bring more water than Bay Area cities’ sewer systems can handle, and the result is more minimally-treated wastewater making its way into the Bay. Most of San…

Planting for soil health

By Lauren Lewis With the arrival of the (hopefully) rainy season, our thoughts go directly to what the rain can do for our gardens. Besides the obvious benefit of free, un-transported, apolitical water to nourish the plants, the rain also benefits the soil, by catalyzing the decomposition of dead plant material that’s lying around. So much of the soil in a city is compacted…

In our Mediterranean climate, the seasons reverse

By Lauren Lewis The tree losing its leaves is arguably the most recognizable image of autumn. In temperate areas of the world, like North America, the most common reason that trees lose their leaves, a process called abscission, is to protect themselves from cold damage. The plant senses a decrease in daylight hours, and responds by withdrawing nutrients from leaves for storage (the withdrawal…

The garden smells we love are plant protectors

By Lauren Lewis If you visit the San Francisco Botanical Garden on a hot day like we’ve been having recently, your nose may well have a more interesting experience than it would on a normal foggy day. That’s because most plants are constantly sending out odiferous volatile compounds (essentially chemicals), and warm air allows those volatiles to move around more and intensify. Some are…

The myth of California wilderness

By Lauren Lewis The concept of “Small Spots in a Big World” is about putting our outdoor spaces in the context of space and time, in order to understand and appreciate them better, and consequently interact with them better. This post focuses on the context of time, on the millennial scale, and the way that plants and people have interacted intimately on the land…

In summer, even the veggies are fruits

By Lauren Lewis Even in a place like California, with year-round food production and farmers markets, farmers depend on bustling summer markets to see them through the leaner winter months. Some of the difference in market attendance is attributable to weather that keeps people away in the winter, but a lot of the difference is certainly due to the produce selection at a summer…

To support public health and education: grow trees

By Lauren Lewis When you stumble upon a street where the sidewalk trees are so big they form a full canopy over the road, it just feels good. (I’m picturing 24th Street in the Mission as an example, from Mission to Potrero.) Something about the completeness of the shade, or the feeling of outdoor enclosure, is rare and lovely in an urban setting. Because…

Striving for ant-human mutualism

By Lauren Lewis The concept of ecosystem services gained recognition and common use among ecologists and policy makers only within the last 20 years or so. Ecosystems services are the benefits that humans collectively receive from the functioning of ecosystems. It’s the natural processes happening around us that we don’t control but that make the world as we find it. There are many examples…

Less-is-more Gardening for the Birds

By Lauren Lewis When it comes to active garden maintenance, the Small Spot crew almost always argues that less is more. We don’t say less is more out of laziness, but rather out of our understanding of the garden practices that can create beauty and sanctuary while simultaneously allowing wild ecological relationships to thrive. The goal of supporting bird life in the garden provides…
