Power has been restored to most of the nearly 600,000 people in Michigan that lost electricity during the ice storm that hit last weekend. The storm coated trees with an ice coating an inch thick in many locations, resulting in widespread tree damage. Exceptional events such as this remarkable ice storm provide numerous opportunities to make some observations about trees and how there were impacted by the event. Here are some notes based on observing trees near my home in DeWitt, MI and driving around Lansing, East Lansing, and the MSU campus.… Continue reading this article “The Ice-pocalypse of 2013: Winners and losers”

(Not so) pretty in Pink
The weekend’s weather forecast portended some lousy conditions and, unfortunately, this time the forecasters got it right. The outlook map for the Lansing area put us squarely in the dreaded Pepto-Bismol pink ‘Icy mix’ swath from Oklahoma to Maine.
Last night and this morning was a non-stop cacophony of “Snap! Crash!” as icy limbs headed earthward. About 4:30 this morning my wife saw a bright flash burst across the street and almost immediately we heard all our of appliances stop.… Continue reading this article “(Not so) pretty in Pink”
This gives “cutting the grass” a new meaning.
No, no, no.
NO.
Textbook “right plant, wrong place.” Miscanthus sinensis is tough, drought tolerant, creates a nice screen, and if the late-blooming cultivars such as ‘Gracillimus’ and ‘Morning Light’ are selected, has little chance of seeding all over. After a few years in place, most cultivars are as wide (or wider) than they are tall. The lovely mounding/flowing habit is why this is the number one ornamental grass sold.
A better option – a very upright grass such as Calamagrostis x acutiflora ‘Karl Foerster.’… Continue reading this article “This gives “cutting the grass” a new meaning.”
The ins and outs of trunk injection
I am serving on a Ph.D. committee for a student working in Entomology and Plant Pathology who is defending his dissertation tomorrow morning. I’m taking a break from trying to plow through the longest dissertation in history: A 465 page tome on the use of trunk injection in tree fruit crops. A lot to wade through but a fascinating topic. Trunk injection, of course, is not a new topic. Some of the earliest references to injecting compounds into trees date back to Leonardo daVinci, who also suggested the ‘pipe model’ theory of tree architecture; the notion that total cross-sectional area of a tree is constant as you move up to higher and higher levels of branching.… Continue reading this article “The ins and outs of trunk injection”
Conventional vs. organic agriculture – the battle continues
An article was published earlier this week comparing the nutritional content of milk from organically raised cows to that from conventional dairies. The principle finding in this report is that “organic milk contained 25% less ω-6 fatty acids and 62% more ω-3 fatty acids than conventional milk, yielding a 2.5-fold higher ω-6/ω-3 ratio in conventional compared to organic milk (5.77 vs. 2.28).” (ω-3 fatty acids are considered to be “healthy” and you’ve probably heard of them in association with fish consumption.)… Continue reading this article “Conventional vs. organic agriculture – the battle continues”
Does anyone really know how to handle weather ? – revisited
There are few things that bind us together like weather. No matter what a person’s socio-economic status, they get wet, hot, or cold just like the rest of us. Ok, if you’re rich enough you can afford to move where the weather suits your clothes, but if you’re like most of us, you have to deal with whatever Mother Nature sends your way. And, if you’re a typical American, few things give you more self-righteous satisfaction than knowing that out of the 300 million people in the country, YOU are the only one that knows how to cope with weather.… Continue reading this article “Does anyone really know how to handle weather ? – revisited”
A Little Woodland Wonder
What’s that bit of green poking through the fallen leaves and forest duff? You’ll have to crouch down to get a good look at Wintergreen (Gaultheria procumbens). A mere 3-5″ tall, this teensy shrublet from the Ericaceae family (blueberry, azalea) has little oval leathery leaves, often mottled with purple or brown. A few urn-shaped pink to white flowers appear in early summer are followed by bright red berries. The berries persist well into the winter and help to distinguish it from similar-looking seedlings of mountain laurel or deerberry.… Continue reading this article “A Little Woodland Wonder”
Silence of the lamb chops
One of my ‘other duties as assigned’ this time of year involves serving as The Christmas tree Guy and responding to various media inquiries about Christmas trees. Last week I posted a link to a media story about Christmas trees on the Garden Professor Facebook page. That post drew a response from Kyle Fletcher Baker who derided cut Christmas trees as “murder of the innocent.” My initial reaction was, “Jeez, Kyle we’re talking about fir trees here not lamb chops or veal.”… Continue reading this article “Silence of the lamb chops”
Working out the bugs
It’s December and I hereby vow to post every week from now on! I’ve actually been on the blog behind the scenes for the last several weeks troubleshooting the archives. We transferred over four years of material from the old site, and there are still some rough patches. And that’s where you can help.
If you have been browsing the archives (listed on the right hand menu) or searching for topics (the search box is in the upper right corner just below the Garden Professors banner where the little magnifying glass lurks), you may have found odd line breaks, broken links, missing pictures, etc.… Continue reading this article “Working out the bugs”
