perfect imperfections: galls and leaf mines, with charley eiseman

New Trees: Recent Introductions to Cultivation by John Grimshaw, Ross Bayton and illustrated by Hazel Wilks. Amazon

Ornamental Japanese Maples are widely available for planting in your garden. The autumn colouring makes these trees spectacular when planted en mass in a woodland or Japanese garden setting.

Have you noticed the persistent brown leaves still hanging on some deciduous trees long after their foliar companions have fallen? This usually becomes very apparent after normal leaf drop in early winter. These brown leaves may remain attached until spring bud growth pushes them free.

Quick backstory: You may remember Charley, co-author of my most-used field guide “Tracks and Sign of Insects and Other Invertebrates,” from our recent interview about galls and leaf mines, two of his specialties.(I’m giving away two more copies; enter by commenting in the form way down at the bottom of this page, after reading the entry details in the tinted box just before that. The book can help you to know what you are seeing when you look closer, too—kind of like always having Charley by your side.)When that story ran, Charley had noticed a photo I used to accompany it–of a squiggly “leaf mine” I’d observed in my Asian-native big-leaved perennial called Petasites. He’d wondered if it was caused by the insect that feeds in a few different genera in the tribe Senecioneae (including some native American botanical cousins of Petasites).  Why don’t you come try to find out, I’d suggested—and while you’re here, why don’t we have a

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.

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

EXPLODING Eremurus, why vulnerability is good for us, and the answer to why bird poop is white—all, and more, in the latest collections of links I’ve loved lately while staring into my computer screen (which I alternately do between long gazes out the window). Five links worth exploring:

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

I PROMISED I WOULDN’T ADD EVEN AN EXTRA TRIP TO THE CURB WITH THE TRASH to my schedule, with all the mowing I have to do, but (big surprise) I layered on a couple of events, and I want to make sure you know about them, in case you are in the Hudson Valley/Berkshires vicinity this summer. Another container-gardening class, a 365-day garden lecture with an extra focus on water gardening and the frogboys, and a tour here in August (that last one you already might know about). Details, details:Sunday July 12, Containing Exuberance, container-gardening workshop, with Bob Hyland at Loomis Creek Nursery, near Hudson, New York, 11 AM to 1 PM, $5.

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.

A little context first: You’re in the Northeast, where a lot of the cases of Lyme in the United States occur, but there are multiple tick species around the nation. You

Charley Eiseman and Noah Charney’s 2010 book is full of photos of all the oddball things you see outside (if you stop long enough to notice!): egg cases and cocoons and all kinds of webs; folded and curled-up leaves as if something’s hidden inside (it is!); and all manner of bumps, lumps, notches, and holes in foliage, bark, you name it. Even tiny previously unexplained pattern in the sand…and soil…a.k.a. tracks and signs of insects.“I’ve always been interested in everything around me,” says Charley, whose Master’s degree is from the University of Vermont’s field naturalist program. “Then someone gave me a digital camera right after I graduated from college, so I started paying closer attention to the little things.  And then I started wishing I had a field guide to tell me what all these signs left by insects and other invertebrates were—but it just didn’t seem to exist.”Charley and Noah took it upon themselves to create that guide, in “Tracks and Sign of Insect

Adam and I talked about not just the Japanese types, but also other garden-sized maples for adding interest in every season and garden situation–in pots or the high shade of woodland gardens, to full-sun locations.my maple q&a with adam wheelerQ. When I was at Broken Arrow recently, there were many choice things to look at—but I kept noticing the maples you offer, particularly. How many do you grow?A. In the collection at the nursery, I suspect we have 150 or 200 different maples, and really that’s the tip of the iceberg with this genus.Q. There are a lot of native A
