With all that in mind, I made my annual frantic call with some urgent tomato questions to today’s guest, Craig LeHoullier in North Carolina, the NC Tomato Man as he’s known on social media, author of the classic book, “Epic Tomatoes” (affiliate link). Craig knows more about these cherished fruits than almost anyone I’ve ever met. He even shares that in live sessions each week on his Instagram account where you can ask your questions and get solid answers. I asked Craig how he’s doing and what we should all be doing to bolster a bountiful harvest and also about which fruits to save next year’s seed from anyhow and other tomato questions. Read along a

Ferns have been on the planet for more than 300 million years—about twice as long as flowering plants—and in recent years breeders with sophisticated eyes have introduced extra-showy varieties for our gardens.No wonder there is a focus on ferns, since they are naturally deer-resistant, mostly adapted to shady gardens, and hey, you don’t need to deadhead them since they’re not flowering plants. You can’t attribute any of those qualities to, say, a daylily.On my radio show and podcast, Tony treated me to a 101 on ferns and how to use them in the garden (that’s a tiny section of the 28-acre private nonprofit Juniper

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. To hear the entire interview, use the streaming player below. You can subscribe to all future editions on iTunes or Stitcher (and browse my archive of podcasts here).growing ame

IF YOU ARE STILL USING any synthetic chemicals on your lawn, I hope you will stop. So does Paul Tukey. When he founded SafeLawns in 2006, Paul says, “It didn’t occur to people that their lawns could be dangerous.”“The sad reality is that we know that a lot of the chemicals used to grow the lawn (the fertilizers), or the chemicals used to control weeds or insects or fungal diseases—all  of these chemicals are designed to kill things, and they can make us very sick, and they make the water very sick, and the soil very sick, and the air very unhealthy.”Giving up chemicals doesn’t mean you have to pave over your front yard.“We will have lawns long after all these chemicals are banned in the United States, as they have been banned in Canada,” says Paul—explaining that more than 80 percent of Canadians cannot use weed and feed products, or glyphosate (the active ingredient in Roundup herbicide) because they are

I invited my favorite fruit expert, Lee Reich, author of many exceptional garden books, including “Grow Fruit Naturally” and “Weedless Gardening” and “The Pruning Book,” to come talk figs on my public-radio show and podcast. (I’m giving away a copy of “Grow Fruit Naturally;” enter by commenting in the box at the very bottom of the page.)I often refer to Lee as “the unusual fruit guy,” because one of his first books I read was “Uncommon Fruits Worthy of Attention.” Lee lives with blueberries and paw paws and medlars and kiwis and of course figs and more not far from me, across the Hudson in New Paltz, New York, on what he calls his farm-den (as in half-farm, half-garden) loaded with unusual fruits.Learn wh

Peter is one of the world’s master bread-makers, and the author of six books on bread baking, including multiple James Beard Award winners such as “Whole Grain Breads,” “The Bread Baker’s Apprentice,” and “Crust and Crumb.” He is a baking instructor on the faculty of Johnson and Wales University in Charlotte, North Carolina, and has even delivered a popular TED talk on the subject.So when was the last time you baked bread—which to my taste competes with homemade soup as the ultimate comfort this time of year, when we gardeners head mostly indoors for the long wait? I interviewed Peter Reinhart on my public-radio show for inspiration on the best-tasting, healthiest ingredients—including some that are gluten free. The transcript of our chat follows:‘bread

Ever wonder, for instance, why some blue hostas turn dull by high summer, or certain yellow and variegated varieties fade worse than others? Or did you know that ‘Halcyon’ (a blue hosta) has produced all the “sports” or mutations above, and more? In a story and a podcast, get to know our most beloved shade-garden standby more intimately than ever before.I suppose I already knew that there are more than 6,000 named hosta varieties, though perhaps merely 500 are truly garden-worthy, says Tony, whose standard is what he calls “The 10-Foot Test.” Meaning:“If you can’t tell it from 10 feet away witho

On my public-radio show, Arboretum director Mark Weathington took me through the years-long process of “discovering” new plants. Plus, Mark highlighted some Arboretum specialties that may belong in your garden, including standout redbuds and mahonias, and the lesser-known evergreen shrub Illicium, and even showy native dogwoods selected to withstand increasingly saline soils in tricky coastal areas.What’s now called the J.C. Raulston Arboretum at North Carolina State University is where I met my first Cephalotaxus–a near-lookalike to our common evergreen yews but excitingly deer-resistant. And then a moment later I met another one–this time a columnar form–an

Q. The subheadline of your edible landscaping book is “With a Permaculture Twist.” What’s that about?A. Permaculture is a holistic landscape design technique that was born in the late 70s. A Tasmanian woodsman-cum-professor and one of his students, Bill Mollison and David Holgrem, generated the design of what permaculture is.It’s ecological design in that it observes natural ecological patterns, and then imitates those in ways to create human-centered habitats.It combines form, function and production—and also includes all the elements of alternative energy, sustainable forestry, of course your market gardening, and all the social dynamics. So it doesn’t isolate any one design element; it puts them all

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

Q. Since all gardening starts with the soil, Ira, one that really caught my eye was the DIY soil test with dishwashing powder and water in the glass jar. A. I first came across the test back in the 70s, when I was a 4-H and Girl Scout leader. The area in North Carolina where I was living at the time had red clay (just like we do here in Virginia).You can sort of tell what kind of soil you have by making a ball of it in your hand, but to be more clear about your soil texture—so you can have a better idea of moisture-holding capacity and how much organic material in the form of compost you need—this test is great.You take a quart Mason jar, fill it one-third to half full with soil. Make sure you’re just getting soil, and not big clumps of grass; go below that, to sample the first 6 inches.A trowel you use for planting bulbs is great for getting a soil profile.Then add water until the jar is about t

A candid head’s up: Like Jeff, I am less-than-enthusiastic about the seemingly widespread desire among gardeners to shop their way out of issues with pests, disease, or soil imbalances. I buy a lot of seeds and bulbs and plants–but not a lot of “stuff.”Jeff and I had a funny email exchange, when I invited him to join me on the radio show and podcast, and asked about what topics he’d most like to cover together.“The topics that I speak on most frequently are garden remedies and thoughtful organic gardening,” Jeff replied. When I read that, my slightly dark humor zoomed in on the phrase “thoughtful organic gardening.”Except I thought he said, “thoughtless organic gardening.” I g
