Organic Gardening Info from Peaceful Valley

Here at Peaceful Valley, we are in the throes of bare-root sales. However, the terms and restrictions for what can and cannot be planted can be confusing, especially for the first time grower.

The first thing to consider is your growing zone. This is a general description of how warm or cold your temperatures get year round. Where people tend to get confused, even experienced growers, is that in the US, there are two different forms of zone charting: The USDA and Sunset Magazine, possibly more. For simplicity, Peaceful Valley employs the USDA chart exclusively.

How, then, can you find, with any certainty, what USDA zone are you in? You can find zone maps in many locations, but even those cannot be as specific as you need. Fortunately, the good folks at the National Gardening Association have put together a searchable zone chart! Simply go here, and enter your zip code. You will get not only your USDA zone, but links to articles pertaining to growing conditions in YOUR area!

Another question many people have is “How many chill hours do I have? What is a chill hour, anyway?” According to Dave Wilson (the company that has supplied the majority of our bare-root trees for nearly a decade, and services many other nurseries around the nation) a chill hour is defined as one hour under 45 degrees Fahrenheit. However, its not always that simple. For every hour over 60 degrees, you have to subtract one hour. There are other, more specific rules (search for Utah Model Chill), but this is a good general guide.

Now, most people don’t sit out with a clipboard and a thermometer every day, calculating chill data. So, to get your approximate number of chill hours, you would go to your local Ag department — they usually have that data. If you are lucky enough to live in California, our wonderful UC system actually has monitoring up and down the state, with not only recent data, but in some cases, going back 5 years — you get a great picture of trends. The website, broken down by county, can be found here.

As always, we are here to help. Our catalog features many different icons to give you an idea of what grows well in warm climates (ideal for areas like Los Angeles), and what grows well in frigid areas, like Nebraska. But remember, we cannot hold shipments until it gets warm enough for you to plant. There is a method called “heeling in”, which allows you to care for your bare root plants until you are able to plant them in their permanent home. The literature we send out with our plants includes that information, but it can be viewed by downloading the .pdf file on the description page of all our bare-root stock.

Good luck, and Happy Planting!

Save Organic Standards: Tell the USDA and the NOSB to Protect Organic Standards

Certified organic food and personal care products are just about the only things sold in grocery stores these days that can be accurately described as healthy, nutritious, safe and good for the environment. (Beyond organic you can vote for economic justice with your consumer dollars by choosing items that are labeled as Fair Trade or Union-Made.) But constant vigilance is required to prevent unscrupulous companies from driving down organic standards, or exploiting their workers. Family-scale organic dairy farmers are being undermined by factory farm feedlots masquerading as organic, as well as Wal-Mart and other national retail chains driving down farm gate prices. Multi-ingredient organic food processors are cutting costs by using the same supply chain as bottom-of-the-barrel conventional brands, with unfortunate results such as the recent peanut butter food poisoning scandal. And, fake organic imports threaten to flood the domestic organic marketplace.

Under the Bush Administration, the USDA National Organic Program contributed to these problems by being slow to address National Organic Standards Board (NOSB) recommendations, issue definitive regulations and enforce existing ones. Under the new Obama Administration, with Kathleen Merrigan as second-in-command at the USDA, we have an opportunity to prevent corporate greed from corrupting organic standards.

USDA Revises Plant Hardiness Map

The United States Department of Agriculture is responding to climate change by updating the Plant Hardiness Zone Map for the first time in 20 years. The map shows where various types of plant species can thrive, and as warmer annual temperatures move northward, the more than 80 million U.S. gardeners and farmers will be looking to the map to see what new plants may be able to grow in their area. The Plant Hardiness Zone Map is typically used for domesticated plants, but this graphic display also sheds light on how native plant species are shifting due to climate change. The updated map is due out later this year.
