The fruits of ‘Juliet’ are somewhere between a plum and a grape or cherry type of tomato— just 2 inches long or so—and borne in clusters of 12 to 18. They’re small enough that I simply halved them (above) for the skins-and-all quick tomato sauce that I freeze 40 containers of each year. I am fascinated with this rich-tasting little plum, now bubbling happily on the stove. Johnny’s Selected Seed rated indeterminate ‘Juliet’ as their most disease-resistant variety in trials (no small honor), I learned today.I have Roberto Flores, the self-proclaimed Dirtmeister at Good Dogs Farm in Ashley Falls, Massachusetts, to thank for growing the brimming bag of ‘Juliet,’ and my crafty neighbor Susan Schneider of Shandell’s, who scooped them up for me yesterday, knowing I’d been complaining about being a bag or two short. And I have the Millerton, New York, farmers’ market to thank, too—appreciation all around, friends.Have you grown ‘Juliet’ (pac

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.

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.

Dr. Tripp, the voice of Robin Hood Radio’s newest program, “Your Health,” received her D.O. from the University of New England. In previous incarnations she has her BS and MS from Cornell; her Ph.D. from North Carolina State University, where she also served as Curator of Conifers for the famed J.C. Raulston Arboretum, and did postdoctoral work at the Arnold Arboretum of Harvard University. She knows from trees and shrubs—and that’s what we talked about:q&a: great trees for gardens, with kim trippQ.What woody plants always got your recommendation—what did you try to encourage clients to plant when you were making gardens for people, while supporting yourself through medical school? A. The first thing I always did, especially with a new client, was to walk around with them and say, “Let’s just see what’s growing here now–what’s out there and doing well,” and have a look at it and see if we like it or don’t. And we’d go from there.I found a few plants in our region that no matter what the conditions, were always doing well—even with deer browse.They were thi

The selection is unlike in the early 1990s, when Ken published his first big shade-garden book and most people knew maybe two, hostas and astibles. Then, gardeners cursed shady areas of their yards as a liability to be eliminated instead of a refuge to be celebrated and expanded upon.Ken has been called the “guru of natural gardening” by “The New York Times,” but I just call him my old friend and the longtime master of the shade, and I’m was glad to welcome him back to my public-radio program to talk about making gardens in th

Carol, who was a longtime educator at the New York Botanical Garden and also worked for the Nature Conservancy, has looked beyond the obvious beauty of native plants and studied their life histories, lore, and even cultural uses. I knew she’d be able to answer my questions:our spring-wildflower q&aQ. I have easily and fairly quickly propagated a good number of wakerobin or Trillium erectum asexually (by division, as in the photo above) from three lonely refugees I found under my front porch 25-plus years ago. Some of the plants self-sowing, too now, Carol. How does the reproductive life cycle of a Trillium work?A. Trilliums are a favorite of many wildflower fanciers, so much so that in Europe, where there are no native trilliums, they are sometimes stolen from botanical-garden dis

Longtime disease ecologist Dr. Richard Ostfeld of Cary Institute of Ecosystem Studies took me through the complex system of animal interactions, the effects of a warming climate, and other factors in the tick-borne disease equation, including advice on when and how to be alert.Admittedly, most of the pests readers ask me about are ones that feast on plants, but this one is not phytophagous but rather hematophagous, feasting on blood:“Ticks: the foulest and nastiest creatures that be.”So said Pliny the Elder, the Roman scholar who wrote a massive na

It’s a staggering number. That would be a lot of holes to dig, or drill, as the Garden begins to enhance and expand its historic Daffodil Hill display first planted in 1920.What didn’t surprise me was the involvement of Brent Heath, a longtime bulb merchant and daffodil hybridizer himself, who’s acting as an adviser in the ambitious undertaking. Brent, whose grandfather began the family bulb business in 1900, joined me on my public-radio show and podcast from his B

Landscape architect Thomas Rainer is co-author with Claudia West of a new book called “Planting in a Post-Wild World” that inspires us to design plantings that function like naturally occurring plant communities. It also instructs how to manage them, not doing painstaking and often impractical garden maintenance, plant by plant, as in traditional horticulture. (Enter to win a copy of the book in the comments box below.)Washington-based Thomas Rainer teaches planting design at George Washington University, and has designed landscapes for the U.S. Capitol grounds; the Martin Luther King, Jr. Memorial; and The New York Botanical Garden, as well as more than 100 private gardens. He is also a keen—and daring–home gardener.I welcomed him back to my public-radio show and podcast. Read along as you listen to the Sept. 21, 2015 edition of my

I talked about watering best practices with New York Botanical Garden instructor Daryl Beyers, author of “The New Gardener’s Handbook” (affiliate link). The popular course that Daryl teaches at NYBG is called Fundamentals of Gardening. And now Daryl, who has more than 25 years’ professional landscaping experience besides his teaching role, has put all the fundamentals into “The New Gardener’s Handbook.”Read along as you listen to the June 29, 2020 edition of my public-radio show and podcast using the player below.

Westwood (below, right, in the lab) directs the Global Tree Conservation Program at the arboretum, which strives to save threatened trees from extinction through collaborations with botanical gardens and universities, and others in China, Europe, and Mexico, as well as throughout the U.S. She has a particular interest in oaks—including a number of American species in trouble—which we also talked about.Read along as you listen to the Nov. 6, 2017 edition of my public-radio show and podcast using the player below.
