Peace is not just the absence of war it can be a reflection of a personal inner tranquility. To many gardeners peace may be a state of harmony with nature. It is a theme of several ‘hard landscape’ projects and sculptural works as shown by the selection of Peace gardens below.

St. Patrick’s Day, March 17, is a popular celebration in the United States, due to the number of Americans, 10.5%, with Irish heritage. One million Irish emigrated to North America, Australia, or other parts of Great Britain in the mid-1800s because of the potato disease now known as late blight. Late blight, caused by the water mold, Phytophthora infestans, destroyed the Irish potato crops in 1845 through 1849 and caused the Irish Potato Famine. Another one million people died from hunger or disease.

The spotted lanternfly (Lycorma delicatula) (SLF) is the latest non-native species to take hold in the U.S. This planthopper is large (about a half-inch long) and originally from several countries in the Far East. It was first found in Pennsylvania in 2014, and active infestations are now established in Connecticut, Delaware, Indiana, Maryland, Massachusetts, New Jersey, New York, Ohio, West Virginia, Virginia, and as of just last week, North Carolina. SLF has not been detected in South Carolina, but it is an insect for which we need to be on the lookout.

ONE OF THE FIRST FRUITS that Josh Kilmer-Purcell and Brent Ridge planted when they took ownership of historic Beekman 1802 farm in Sharon Springs, New York: gooseberries.  Now the city-turned-country pair are having a bumper gooseberry year—and Josh joined me on the radio to talk about that and other aspects of “The Heirloom Life,” the subject of the duo’s breakfast slide lecture in my town August 17 to help celebrate my next garden Open Day. I’ve pre-ordered a couple of copies of the “Beekman 1802 Heirloom Dessert Cookbook” (due out in September) to share with some lucky winners, so read on for a chance to win–and some gooseberry lore, recipes and more.

FOR THOSE OF YOU IN THE AREA, meaning the Hudson Valley of New York State or thereabouts, these spring events here in the garden and elsewhere may be of interest: Saturday March 14, Spring Garden Day, Cornell Cooperative Extension of Rensselaer County. (518) 272-4210. This popular, day-long annual event in Troy, New York, includes a choice of classes, from growing orchids at home to successful vegetable gardening.

Lee’s tips for growing pawpaw or American persimmon couldn’t make it sound more appealing, or simple:“Plant it, water it, and keep weeds and deer away for a couple of years, and then do nothing,” he says. No fancy pruning (like those apples crave), no particular pests–and a big, juicy harvest. More details on how to choose which variety to grow are included in the highlights from the April 29, 2013 edition of my public-radio show and podcast, transcribed below.

In the fall of 2016, Dr. Connally won a $1.6 million grant from the Centers for Disease Control to fund a four-year study, in coordination with the University of Rhode Island, to gauge the effectiveness of various tick control methods in the areas around people’s homes. She’ll tell us more about the angles being pursued, and also about self-care topics, from treated clothing to the use of topical repellents and more.Read along as you listen to the Dec. 11, 2017 edition of my public-radio show and podcast using the player below.

So I can invite guest experts to join me as well as share the program with other public-radio stations, we’re pre-taping “A Way to Garden With Margaret Roach” to stand alone, instead of airing live as part of my local station’s morning show, which it has been since March 2010.You can listen in to the first such standalone show here, right now. This week’s topic: When to sow what seeds, with guest Dave Whitinger of All Things Plants in Texas. Next time (February 4), the topic is why I’m going to grow calendul

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

DID YOU KNOW that robins can count, or that food (not paper or plastic) is the biggest single source of fodder for U.S. landfills? Those stories, and more, are among the latest links.

I actually have no certain diagnosis; so many of these issues look somewhat alike, unless you are a plant pathologist, and so far I only have a relative few affected leaves. I nevertheless love Cornell’s diagnostic tool, a photo-driven system arranged by plant part (leaves, stem, fruit).What I do not seem to have, thankfully, is the late blight that’s been the source of the most dramatic headlines, and of a thorough story by Adrian Higgins of The Washington Post, late last week. This dramatic outbreak has also prompted warning bulletins from Cornell and other extension services. My plants have none of its characteristic early sign: dark stem lesions.This is the affliction (affecting tomatoes and potatoes) that caused the 1840s Irish Potato Famine, and it has never been recorded this early in the United States, apparently, nor this extensive

Research from the nearby Cary Institute of Ecosystem Studies in Millbrook, New York, reveals how acorns initiate a complex series of ecological chain reactions. And not just the obvious ways, like feeding turkeys or chipmunks or deer, but in influencing Gypsy moth outbreaks and tick-borne disease risk, and even the reproductive success of ground-nesting songbirds.Dr. Rick Ostfeld, a disease ecologist from Cary Institute, helped me understand what–both seen and unseen–is going on with those tiny acorns and their mighty, wide-ranging influences.
