Short post today — Linda appears to have transmitted her illness electronically over a couple of thousand miles — Thanks Linda!
I was reminded yesterday that it’s almost time for gardeners to start worrying about winter deer damage. With that in mind I thought I’d share with you my favorite research article on the subject. It’s a little paper by Michael Fargione and Michael Richmond and published about 18 years ago. You can find it here.… Continue reading this article “Soap and Deer”
Well, I’m recovering from this simply horrific chest cold or whatever it is and feeling brain function returning. The last time we were at our virtual nursery, we were looking for root flare and inspecting the trunk for damage from improper bagging. Since we’re already down on our hands and knees, let’s consider roots. In general, you really don’t want to SEE roots, except where they meet the trunk (the root flare). The presence of coyly crossed “knees” in this photo is a clear indicator of a plant that wasn’t potted up quickly enough:
Likewise, while the fused, circling woody root mass in this next photo might be aesthetically interesting, it sure doesn’t make a functional root system:
It’s pretty easy to avoid these types of plants, because you can see the root problems before purchasing. … Continue reading this article “Inspecting nursery plants, part ll”
My news tab in Firefox is the BBC “latest headlines” page. It’s a great place to get pretty darn unbiased news plus the U.K. equivalent of “News of the Weird”. SO, relative to our ongoing discussion of composting…here’s a story ripped directly from the BBC headlines. Follow the link for a video (interview, that is).

Recently I was asked to comment about a rash of e-mails floating around cyber-space concerning the toxicity to dogs of mulch made from crushed cocoa bean hulls. Cocoa mulch is by-product of cocoa production. The dark brown mulch is aesthetically and aromatically pleasing, giving the garden a rich, chocolately scent. Since theobromine, a naturally occurring compound in chocolate is toxic to dogs, the internet is now filled with cyber-legends of dogs eating cocoa mulch and keeling over dead.… Continue reading this article “Will cocoa mulch kill my dog?”
So back in September my department head (who is, for all intents and purposes, my boss) handed me a New York Times article (http://www.nytimes.com/2009/09/24/garden/24garden.html) about the grass at Harvard which is now being managed organically. We share the opinion that many organic techniques, such as compost tea, are “Voodoo Science” (that’s a term I stole from Mike Dirr) and so she thought I’d be interested in the techniques that Harvard was using. She didn’t say it explicitly, but I think she thought I’d get a laugh out of it. … Continue reading this article “If Harvard Says That It Works Then It Works Dammit!”
“Dabney! No! Wait!” Just kidding. Dabney Blanton, our lovely and talented horticulturist, knows not to prune the Artemisia in the autumn.
I imagine most gardeners have experienced a frost or freeze by now [exceptions: our Southern Hemisphere readers (howdy to Jimbo)…or anyone in the deeeeep south].
The perennials here in Blacksburg have taken a couple of hits; time to start trimming things back. In the Hahn Horticulture Garden and in my own personal garden, we like to leave perennials and ornamental grasses up as long as possible – gives us something to look at besides mulch, plus the wee birdies enjoy it.… Continue reading this article “To Prune Or Not To Prune, That Is The Question…”
I just had a long conversation with Michele Owens (of Garden Rant fame) about vegetable gardening. This isn’t one of my strong areas, either professionally or personally (I do have containers of herbs, but that’s as far as it goes). But what piqued my curiosity was her revelation that the vegetable gardening is just as full of myths and misinformation as my field of ornamental landscaping.
I’ve ventured into the realm of vegetable garden science now and then, especially in reference to having soil tests done before planting edibles (good!),… Continue reading this article “Veggie gardening science – whaddya know?”
Following up on Holly’s theme of “I can’t believe I get paid to do this”, last Wednesday I participated in a walk-through and inspection of the Justin ‘Chub’ Harper Collection of Dwarf and Rare conifers at MSU’s Hidden Lake Gardens in south central Michigan. The Harper collection is widely regarded as one of the premier collections of rare and unusual conifers in the world.

A little background: Chub Harper was the former grounds supervisor for John Deere’s world headquarters in Moline, IL, an avid plant collector, and a founding member of the American Conifer Society (ACS). … Continue reading this article “The World According to Chub”
Here’s the follow up picture from Friday’s puzzler:
As you can see, there’s a street light near the lower half of the maple. (I cleverly hid it behind the utility pole in the first photo.) The green part of the tree never received the message that days were getting shorter, since the street light is bright enough to interrupt the dark period necessary to initiate dormancy.
This is one of my favorite phenomena unique to urban environments. … Continue reading this article “I see the light!”
Here’s a photo I took in Buffalo about 20 years ago. Buffalo, like many places in the northeast part of the country, has fantastic color changes in the fall. This maple seems to have changed its mind part of the way through the process:
What do you think caused part of this tree to retain its green leaves? Answer and another photo on Monday!
