How Do Purple Flags Fight Climate Change?

What we are learning now is that the presence of green growing plants is even more important to building a living soil than the presence of decomposing organic matter. By planting a mixed perennial meadow under our fruit trees instead of constantly disturbing the soil with weeding, we are adding much more carbon to our soil over time than we could by simply mulching. While getting rid of the oxalis weeds is great, getting rid of the carbon dioxide that is driving climate change is much more important.

Fight Climate Change in Your Backyard

Scientists are telling us unanimously that our use of carbon based fuels is changing the balance of gases in our atmosphere. Of course, we have to stop burning so much fossil fuel. But we also have to start taking carbon out of the air and ‘sequestering’ or storing it somewhere else. Luckily, nature already has a way of doing this. It’s called photosynthesis, and green plants do it all day long. They take carbon dioxide out of the air and store it in their bodies. Their roots also carry it deep into the soil and store it underground.

One of the Verbenas needed to be moved out from under the shade thrown by a huge Salvia karwinskii. There was never a better day for a sharp pair of pruners.

The Nutritious Solitude of Gardening

Gardening is an odd combination of solitude and company. Many of us do the actual work of gardening alone for hours. This is when gardening books and garden writers become important allies. The best books scold and strategize as well as inspire and encourage. They remind us of what is possible as well as saying “I told you so.” They become good friends, whose humorous critique and encouragement are as useful as any other garden tool.

100 Words for Drought Tolerant

As water policies and practices come under more and more pressure from increased demand and shrinking resources, we need one hundred words for drought tolerance. Part of the task of the Garden for the Environment is to refine what this word can mean, and experiment with real world plants, soil, weather, and exposure to find out which plants can thrive with little or no reliance on summer irrigation.
