Did you ever know one of those annoying people who always talks about how great everything is back wherever they were from; the kind of folks that make you want to say, “If things were so much better there, why are you here?” I have to confess I’m one of those people. No one’s ever actually given me the “If things were so much better there” line, but I’m sure my Michigan friends have been tempted. … Continue reading this article “Fall color time…”

Pop quiz answer
Today’s post is a follow-up to yesterday’s quiz on foliar fertilization. I asked our blog readers to match the needle nitrogen content of Nordmann fir trees with the fertilizer treatments they had received.
Nutrient deficient Nordmann fir
The correct order is:
1) control: no fertilizer 0.98%
2) soil applied controlled release fertilizer 1.70%
3) foliar nitrogen fertilizer 1.14%
4) soil applied fertilizer + foliar feed 1.91%
While the foliar fert had a small effect, it’s important to note that, from a statistical standpoint, foliar fertilization did not significantly increase needle nitrogen concentration. … Continue reading this article “Pop quiz answer”
Pop quiz time!
It’s the start of new semester. Best way to get student’s attention is with a pop quiz right off the bat! So in that vein, we’ll cross things up and give a quiz on Monday instead Friday. Relax; to make things a little easier we’ll make this one a matching exercise.
Here goes. At our recent Christmas tree conference in Austria, a colleague of mine at Oregon State University, Chal Landgren, presented the results of a study to look at the effectiveness of foliar fertilization on Nordmann fir. … Continue reading this article “Pop quiz time!”
Just for ewe: An alternative approach to weed control.
As I mentioned in the last post I was in Austria this past week for the International Christmas Tree Research and Extension conference. We hold these meetings every two years for Christmas tree researchers in Europe and North America to get together and share the latest research on various aspects of Christmas tree production and marketing. In addition to research presentations the programs also include tours of local Christmas tree farms, which is always the most interesting part of the conference.… Continue reading this article “Just for ewe: An alternative approach to weed control.”
If it’s Monday this must be Austria…
Just a quick post from on the road. My family and I have been traveling through Europe the past week and a half. A bit of a whorl-wind trip combining some vacation and work travel. We started off a week and half ago, flying into Frankfurt. We rented a car and drove to Paris where we spent a couple of days sightseeing. Then it was off to southern France to visit friends that run a bed and breakfast there.… Continue reading this article “If it’s Monday this must be Austria…”
Toxic mulch: When shredded bark goes bad
We typically think of mulching landscape beds as a good thing. And it usually is; helping to conserve soil moisture, reducing soil temperatures and contributing to soil organic matter. Recently, however, I received an e-mail from a local landscaper that reported severe damage to annuals and perennials in a landscape bed immediately after applying hardwood mulch. The problem, sometimes referred to as ‘sour mulch’ or ‘toxic mulch’, occurs when mulch is left is large piles and undergoes anaerobic conditions. … Continue reading this article “Toxic mulch: When shredded bark goes bad”
This Bud’s for you…
Ask the risk of honing in on Jeff’s turf, I thought I’d pass along this article by former University of Maine associate dean (and apparent Garden Professor wannabe) Katheryn Olmstead. It seems that Dr. Olmstead’s painstaking research has documented a preference among slugs for domestic beers, particularly Budweiser. http://bangordailynews.com/2011/07/21/living/garden-slugs-prefer-budweiser-over-foreign-brands/ Like most undergraduate students, it seems slugs prefer domestic swill to more refined imported brews; confirming many suspicions about both slugs and undergrads. Although we’ll have to wait for the full peer-reviewed article, her scientific method seems sound, including use of replicated plots. … Continue reading this article “This Bud’s for you…”
Spin Cycle
The issue of potential damage to conifers by the turf herbicide Imprelis continues to get a lot of air play in this neck of the woods. One of the interesting things about watching an emerging story such as this is watching some of the sideshows that go on around it and how people spin the issue to match their needs and agenda.
Example 1:
Heritage Lawn Care Company put out flyers in neighborhoods in southeast Michigan with affected trees to promote their service. … Continue reading this article “Spin Cycle”
Imprelis update
I’ve been continuing to track some of the reports of injury to conifers associated with the new herbicide, Imprelis. Interest in the problem is likely to escalate given a front page article in the Sunday’s Detroit FreePress. http://www.freep.com/article/20110710/NEWS06/107100467/New-lawn-chemical-chief-suspect-mysterious-deaths-trees
I visited about ten sites last week with an applicator that had used Imprelis this spring. The landscaper was a certified applicator with about 15 years of experience with herbicides, insecticides and fungicides, who was knowledgeable about his chemicals and plants.… Continue reading this article “Imprelis update”
Does native matter?
We’ve had lots of lively discussion on my post regarding the Mark Davis et al. comment in Nature on natives and exotics. I have been traveling and otherwise occupied and have not had a chance to comment so I feel a little like the kid that kicked the anthill and then ran away. Fortunately, Holly was gracious enough to forego her post today (I promise to return the favor, Holly!) so I can chime back in.… Continue reading this article “Does native matter?”
