Sunshine, precipitation, heat, cold, seasonal variations, altitude; all are critical considerations when planning and maintaining a successful garden. Knowing which plants do best in your climate, which conditions encourage growth, and how drought and other weather changes can affect what and how you grow is essential to wise gardeners. We discuss the issues — from shade and frost-tolerant plants to heat and drought-resistant gardens — important to every grower.
100 billion gallons of water, in the form of alfalfa, shipped to China. How can we use less water to grow the produce needed in this country?
Here’s one effect of the drought in California and elsewhere: there’s been a lot of fascinating reporting on water use in commercial agriculture. And the amounts of water that go into some crops, and where those crops are headed, has created something of a controversy.
It comes as no surprise that much of the produce grown in the United States comes from California. Some 95% of all the broccoli, 92% of all the strawberries, 90% of all the tomatoes, and 99% of all the almonds grown in this country come from California. (more…)
News items on student gardening programs, marketing food by resisting factory farms, and the complications of climate change.
Learning about gardening one cabbage at a time: Let’s start with some good news. Bonnie Plants, one of the nation’s largest suppliers of plant starts, has announced the winners of its 3rd Grade Cabbage Program. A winner, randomly chosen from each state, will receive a $1,000 savings bond to be applied to the student’s future education.
We don’t have to tell you. The news from many parts of the west is all about drought. You can find accounts of what’s being faced, including the potential for cutbacks and rationing, here, here, and here. And the forecast for the coming months doesn’t look good.
No matter if you believe that drought is just a part of the natural cycle (it is) or is a product of global warming (we don’t see this as an easy either-or question but think both factors could be in play), dealing with a lack of or more expensive water is something that gardeners frequently face. Even as a back-to-the-land, ex-hippie in the 19(garbled) living on the edge of the rain forest in Washington State we had summer months without rain some years that meant the buried reservoir that collected water from our spring filled more slowly and even ran dry when we watered our rather large garden. That’s the problem with water: you run out just when you need it most. (more…)
Greenhouses are wonderful places, especially in the spring when benches are filled with brilliant green starts, and in the summer, its doors and roof vents propped open, with cucumbers trailing from the ceiling and tomatoes ready for picking. But in winter? Not so much. Overwintering herbs and potted plants cluster together for warmth. A few brown, leafless cucumber vines hang from an overhead trellis. Kale and spinach are over-picked and the seeds you planted have yet to sprout.
It’s a winter-time fact in most parts of the country: greenhouses, even those that might be attached to the house or garage, need some kind of heat source (of course, supplying appropriate light is equally important). (more…)
We love the first days of winter, the last days of the year. We love these days as much as we love the growing season, but in a different way. We think there’s a reason so many faiths have holidays this time of year and, it seems to us, people are just a bit more considerate, more thoughtful, more generous, and more out-going this time of year. We’ve passed the longest night of the season, the winter solstice, and now the sun’s slow climb in the sky, spending more time with us each and every day until the summer solstice, is something of a beacon of hope, a reason to anticipate the return of our gardens and landscapes from their winter sleep.

—False Assumptions and GMOs: The spread and use of genetically modified crops in the production of food is a highly controversial topic… no need to tell you that. The arguments for their use are often based on false assumptions. This wonderful article from Ensia, a magazine that comes from the University of Minnesota’s environmental department, highlights some of the wrong thinking in terms of increasing food production that is often sold to us as an important reason for the growing of GMO crops.
The writer, Jonathan Foley, reminds us that most of the GMO crops grown aren’t grown as food and are only involved indirectly in the production of other, processed foods. Here’s how it opens:
You’ve probably heard it many times. While the exact phrasing varies, it usually goes something like this: The world’s population will grow to 9 billion by mid-century, putting substantial demands on the planet’s food supply. To meet these growing demands, we will need to grow almost twice as much food by 2050 as we do today. And that means we’ll need to use genetically modified crops and other advanced technologies to produce this additional food. It’s a race to feed the world, and we had better get started. (more…)
For a lot of us, November marks the end of our outdoor gardening season. There’s still puttering to do: cleaning and oiling tools to be put away for the winter, bringing indoors any potted plants we may still have outside, trimming back and protecting roses; that kind of thing. Often we’ll wait for a sunny (relatively) warm day to do these things. But as all of us have heard said — thank-you, Coach Kruger! — it ain’t over ’til it’s over. And in gardening, that means it ain’t over until the ground freezes, no matter what the calendar says.
We’ve been reading environmental activist and author Bill McKibben’s new book Oil and Honey: The Education of an Unlikely Activist (here’s an excerpt) and finding it entirely fascinating. It’s the story of McKibben’s life in 2011, the year he and his organization 350.0rg spent time protesting the XL Pipeline that would carry tar sands from Canada to the refineries on the Texas Gulf Coast.
You don’t have to be a strong opponent of the pipeline or even actively engaged in fighting global warming (or even worried) to enjoy this book. True to its subtitle, it tells how McKibben, an environmentally supportive author from Vermont, became educated in the ways of politics and activism during a year that preceded a national election even as the country experienced a crippling, almost nation-wide drought and record shattering heat.

Friends that read this blog are always anxious to offer criticism, point out mistakes, and otherwise find things I’ve said that just might not be true in every case. Rather than get all defensive, we’ve learned to engage our fact-checkers, address the questions and, more often than not, learn something in the process.
So when a couple of longtime gardeners began taking exception to some of the things I said in “Overwintering Potted Plants,” I paid attention. Much of what they commented on wasn’t about out-and-out mistakes. Most of the corrections and considerations my friends made were of the “not true in every case,” and “you failed to make the distinction,” and, best (or worst, depending on your point of view) “you promised the moon” sort. So let’s start with the moon. (more…)
Techniques to protect plants in pots from cold and freezing weather.
Those of us who use potted plants in our gardens, on our patios, and around our landscapes face a problem each winter: how to protect them during the long cold winter. It’s hard enough in areas where extreme cold is frequent to keep perennials in the ground alive. It’s much harder overwintering potted plants. The bulk of soil that is in the ground tends to moderate the temperatures. The small amount in pots tend to give up heat more readily. What to do?
The general rule of keeping plants in pots two zones different than the zone you live in helps. In other words, if you live in zone 6, make sure the plants you have in containers are rated to zone 4. (more…)
