REGULAR READERS know that I preach the doctrine of, “Know thy weeds.” I’m a passionate believer that you cannot possibly subdue plants whose life cycles and survival strategies you do not know—and you can’t research clues to those workings if you don’t even know the plants’ proper names.
One of the best resources ever for those wishing to know their weeds is the book “Weeds of North America,” published in 2014 by University of Chicago Press, and co-authored by Richard Dickinson, with France Royer. Since its release, it is always at the ready here—with information about 500 species, plus photos of most every one at every life phase from seed to seedling to full plant and leaf and flower detail. There will be no mistaking weed from wildflower or garden plant again.
Toronto-based Richard Dickinson has taught plant taxonomy for more than 25 years, and he joined me to talk about every gardener’s favorite—or is it unfavorite?—subject, weeds. I learned how they get so good at being weedy, and what their environmental impact is beyond taking space away from desired plants (spreading plant diseases, or harming monarch butterflies, for example). I also got a 101 on how gardeners can learn to “key out” one plant from another, using simple clues like a taxonomist does.

my weed q&a with richard dickinson
Q. What got your started with weeds? I have to ask. It’s an interesting path; I get when people are into plants—and of course weeds are plants. [Laughter.]
A. It’s interesting because our first few field guides were

I have been reading the Penguin Encyclopedia of Gardening which aims to provide ‘….an explanation of words used in a technical sense in a horticultural context in the UK and USA.’ Set out as an A to Z this resulting post, missing a thousand definitions, is unlikely to rank highly with search engines.
As summer arrives, I’m drawn outdoors whenever possible to make the most of the long days, but as I work from home I still have to spend quite a lot of time inside, in front of my computer. Fortunately, the house plants that fill my home provide a wonderful link with greenery and nature, and, at the height of summer, the lush, verdant foliage helps me daydream about holidays in far-flung destinations.
Requiring less watering and weeding than any other type of garden, a gravel garden is ideal for anyone with a busy lifestyle. Comprising freely draining soil covered in gravel, through which suitable plants grow, the only effort required is in its creation; after that, this contemporary form of garden largely looks after itself.
Winter is the perfect time to install a drainage solution to remove standing water in the yard by adding surface drains, French drains, or both. Removing excess standing water helps with disease prevention in turf. Many turf diseases are made worse by prolonged wet conditions.
No rain.That about sums up how I feel about the so-called gardening season of 2010. No rain. Believe me, you don’t want to hear me say much more, as it gets ugly fast.The only good parts: few fungal diseases and lots of frogs (who stayed here with me by the little backyard pools in even larger-then-normal armies–as groups of frogs are called–since there wasn’t much moisture in the vicinity otherwise). Lots of a
Andrew, who is now assistant director of the Chicago Botanic Garden, is past president of Magnolia Society International’s board of directors, and remains a member of the society’s board. In his tenure over 20 years as curator at Scott Arboretum of Swarthmore College in Pennsylvania, Andrew built the magnolia collection from about 50 to more than 200 cultivars. That’s a lot of magnolias.Now Andrew Bunting is author of a book on the queen of flowering trees, called “The Plant Lover’s Guide to Magnolias,” just out from Timber Press as part of an ongoing series on various distinctive genera of plants.We talked magnolias on my public-radio show and podcast.

Each of her 150 recipes is delightfully prefaced with what amounts to its provenance: a juicy and sometimes hilarious back story that Clark tells in as simple yet deft a fashion as the style of the dish that follows. I sat right down to chapters like “Better Fried” and “It Tastes Like Chicken” and “My Mother’s Sandwich Theory of Life,” the perfect mix of a good read and a good meal.For me—a flavor-fearing kid who rinsed most of her entrees off at the sink conveniently positioned halfway between the Garland range and the family dinner table—Clark’s childhood tales are positively hair-raising: Summer vacations were spent touring France with her psychiatrist parents, gourmands determined to eat at every Michelin-starred restaurant there. Worse yet (or to Clark, more thrilling): Th
I SAY THANK YOU to the University of Chicago Press for investing in “Weeds of North America” (above) by Richard Dickinson and France Royer. The Canadian authors have created a massive work (800 pages paperbound) covering 500 of the continent’s pest plants, including aquatics. Key ID tips include not just flower and foliage photos, but also images of seeds and seedlings.This serious reference volume illuminates other reasons to consider the plants as pests, beyond the space they steal from natives. Such traits include toxicity to livestock (like milk thistle) or transmitting a disease to a valuable crop (like barberry does w
I CAN’T SEEM TO KEEP MY TOMATOES (or anything else) well watered enough in this dry year, and am expecting some kind of havoc as a result. Extended 90-degree daytime temperatures have already caused some flowers to drop before producing, for instance.
