Natives vs. exotics. We’ve heard that before haven’t we Bert? Well, here’s an interesting little nugget published recently in the journal Ecology Letters. Exotics and natives are different, and their differences allow them to coexist. In this study exotics were superior to natives in terms of growth, but were fed upon more by herbivores. Interesting. Of course there are lots of different types of exotics and natives, but the plants that these researchers looked at had been living together for about 200 years. … Continue reading this article “How Can Natives and Exotics Possibly Coexist?”

Ornamental Peppers for the Holidays (!)
Growers and garden centers are always on the lookout for Poinsettia alternatives. Points make up the vast majority of potted flowering plants sold this time of year, but other crops are gaining ground. Due in part to the popularity of All-American Selection (AAS) winner ‘Black Pearl,’ there’s been an explosion of ornamental pepper varieties. Most are pretty versatile – can be used as bedding plant, in containers, and as a potted flowering plant. Edible? Depends on your threshold for pain.… Continue reading this article “Ornamental Peppers for the Holidays (!)”
A holiday gift idea
In deference to the holiday season, I’ll step down temporarily from my soapbox and mention a great holiday gift idea for your favorite gardener.
I saw this sedum stump a few years ago when I was speaking to a Master Gardener group in British Columbia. The porous nature of the stump would make it easy for the roots of the sedums and other rock-garden types of plants to establish. And the stump could be easily moved to wherever the recipient desired.… Continue reading this article “A holiday gift idea”
Why oh Why? Christmas tree edition
Hope everyone has had a chance to digest their Thanksgiving meal and is spending a productive day at work shopping on-line. My daughter and I enjoyed one of our Holiday traditions this weekend and brought home a Christmas tree from a local choose-and-cut farm. This was followed by another tradition at our house known as the “Annual cursing of the Christmas lights.” Seems like no matter how careful I am when I put away the lights when we take down the tree, they are always a mangled mess the next year.… Continue reading this article “Why oh Why?

Thanksgiving
Yesterday was the day before Thanksgiving. In my plant production class I always set up a short lab for Wednesday afternoon so that students can leave early and get to wherever they need to go (hopefully to see family). As usual, I got to lab a little early so that I could get the students going right away. Waiting for me there was one of my students.
Earlier in the year I had told the class about commercial mycorrhizae and how the beneficial spores that you think you’re buying are usually dead when you purchase the package. … Continue reading this article “Thanksgiving”
Research that gardeners should appreciate!
Today I received my November 2012 issue of Arboriculture and Urban Forestry. This is one of the few peer-reviewed journals that generally has information of immediate value to gardeners and landscape professionals as well as academics. This issue contains an article entitled “Evaluation of biostimulants to control Guignardia leaf blotch (Guignardia aesculi) of horsechestnut and black spot (Diplocarpon rosae) of roses.” (And before you ask, no, I can’t attach the article or link to it. … Continue reading this article “Research that gardeners should appreciate!”
What would YOU do?
Once in a while we end up flicking around the dial on Friday evenings and land on a show called “What would you do?” It’s a hidden camera-type set up where viewers get to see the reaction of everyday folks faced with awkward or contentious situations like an overbearing customer berating a waitress over a minor mistake in their bill. The scenarios are played out by actors but the people responding are not. Personally I find the premise of the show slightly annoying because it smacks of entrapment but it seems to lure in the rest of my family.… Continue reading this article “What would YOU do?”
A Note To Horse Owners
Every once in awhile I get to work with really, really cool people who do really, really cool work. This is one of those times. About a year ago I received a message from Dr. Stephanie Valberg, a Professor over at the University of Minnesota’s Equine Center. It seems that she was interested in looking at a deadly disease called Seasonal Pasture Myopathy which she thought might have something to do with horses ingesting maple leaves. … Continue reading this article “A Note To Horse Owners”
Cold Weather Discussion
Next Monday Nov. 19th, we’re going to have a google+ discussion (that means digital cameras) on getting ready for cold weather. It will be scheduled for 2:00 Central, 3:00 Eastern, 1:00 Mountain, and 12:00 Pacific. It will be Linda, Myself, and a few other people.

We’d like to get three or four people from cold climates on with us!… Continue reading this article “Cold Weather Discussion”
Important, must-read announcement regarding pesticide use
There’s a new report out from the Weed Science Society of America (WSSA) which blasts a common piece of gardening advice: use least toxic pesticides only as a last resort. Popular as it may be, this advice is not scientifically grounded and can actually cause more harm than good. The WSSA is joined in this announcement by the American Phytopathological Society (APS) and the Plant-Insect Ecosystems Section of the Entomological Society of
America (P-IE ESA).
This is a must-read for anyone who is a responsible educator regarding pesticide use, which includes Master Gardeners and other horticulture paraprofessionals. … Continue reading this article “Important, must-read announcement regarding pesticide use”
