A couple of weeks ago I was interviewed for the local paper about this year’s fall color. It’s pretty standard fare around these parts; newspapers, AAA, and so on want to know if we’re going to have good fall color, will it be early, will it last long. I mentioned to the reporter that we’re seeing a lot of early fall color in the maples around mid-Michigan, in contrast to the northern part of the state, which appears to be running a little late. … Continue reading this article “Support your local arborist”

Old Books
It’s a rainy day in the upper Midwest. My favorite time to read. Of course, I should be writing papers, grading papers, or setting up seminars for next semester. But instead I’m drawn to my bookshelves. In most professors offices that I visit the shelves are an odd mix of old and new books that focus on the particular subject which that professor works on, along with the scientific journals that relate to that discipline. It’s no different in my office, except that I tend towards older books and my tastes are just a little bit more eclectic than most. … Continue reading this article “Old Books”
Rubber mulch rubs me the wrong way
I’ve been receiving a lot of questions about rubber mulch lately. For those of you not familiar with the product, it consists of shredded tires that can be dyed and used on ornamental landscapes or under playground equipment. In fact, the Obamas had this material installed underneath their children’s play structure at the White House. It seems an ideal way to recycle the 290 million scrap tires we generate annually.
But is it?
It’s not effective: One of the main reasons we use mulch is to suppress weeds. … Continue reading this article “Rubber mulch rubs me the wrong way”
Buddleia or Buddleja? I prefer butterfly bush…
…because apparently they can fly:
Buddleia or Buddleja?
I recently heard that Mike Dirr has come out with the next edition of his book on woody landscape plants. Dr. Dirr (I can’t seem to bring myself to call him Mike, even after all these years) was my major advisor in graduate school, so I’m really looking forward to getting it. In the meantime I heard that he included a section on my thoughts about how to spell the scientific name of the butterflybush, a plant that I worked on to get my Ph.D.. … Continue reading this article “Buddleia or Buddleja?”
A Brief Discussion on the Wisdom of Barberry as Median Plant
We never know who to blame (or, rarely, thank) for roadside or median plantings. State D.O.T.? Local municipality? Subcontractor to either of the previous?
A few years ago, this appeared in the median of the Highway 460 bypass – the main road leading to Virginia Tech:
I am somehow reminded of Sideshow Bob from The Simpsons…
Two hedge rows. One of green Japanese barberry (Berberis thunbergii, cultivar unknown); the other of the purple form (Berberis thunbergii var.… Continue reading this article “A Brief Discussion on the Wisdom of Barberry as Median Plant”
Modern day torture stakes
Torture stakes were used centuries ago as a slow means of executing prisoners. Unfortunately, the practice lives on every time someone incorrectly stakes a newly planted tree. Though I’ve written about tree staking before (click here to read more), I’ll use today’s blog to demonstrate another unintended result of improper staking – decapitation. A normal tree develops taper as it grows. At eye level, a tree trunk is narrower than it is at ground level: that’s taper. … Continue reading this article “Modern day torture stakes”
The Pile Of Ash On My Floor
Part of the problem with being a professor is that companies assume that I have a bottomless supply of funds to test their products and that it is, in fact, my duty to do so. And of course they assume that this testing will ultimately find their product useful.
The truth is that I do love to test things, but I don’t have the funds to do the comprehensive tests that these companies usually want, at least not without them helping out at least a little – and most of them don’t want to spend money on tests! … Continue reading this article “The Pile Of Ash On My Floor”
Bad roots and deceptive marketing
I guess today’s blog should be entitled “The Cranky Garden Professor.” Really, I’m not always cranky, and when I am I go outside to do something constructive in my garden. Last weekend I finally tackled a 5-gallon container of lavender that I’d bought several weeks ago. I had intended to wait until fall to transplant it, but I was watering it every day to keep it from wilting. I figured I might have better luck getting it into the soil where a good mulching would help keep the soil moist without daily watering.… Continue reading this article “Bad roots and deceptive marketing”
