We’ve finally gotten our summer here in the Pacific NW and it’s been pretty hot for a few weeks. The plants weren’t really prepared for this, so we’ve had to irrigate quite a bit to keep all that lush foliage happy. So the topic of this podcast is Water Works – focusing on how water moves in the soil and through plants.
One of the more interesting tidbits I found this week is a recent USDA study on growing more potatoes with less water.… Continue reading this article “Podcast #8 – Water Works”
Just a short (but irritated) note about the latest fawning over compost tea. Please, people, as Jeff pointed out nearly two years ago on this blog, just because Harvard (and now Berkeley) buy snake oil it’s not transmogrified into science. Middle America would be better served by using compost as a mulch and letting nature make the tea.
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!”
This past summer I had the chance to talk with an old friend of mine, Hamado Tapsoba, who I hadn’t seen in 15 years. We had gone to graduate school together, but after graduation he headed back to Burkina Faso, and I headed up to Minnesota. Anyway, while we were talking I told him that we were growing peanuts at the University (yes, I tell everybody — peanut news needs to be shared!). When I told him some of the problems that we had with shorter seasons he asked why we weren’t growing Bambara groundnuts. … Continue reading this article “Bambara”
This week’s podcast is dedicated to anthocyanins – those pigments that give plants red, blue, and purple colors. Anthocyanins are also powerful antioxidants, important visual signals for pollinators, and often deadly to insect pests. The myth of the week explains why red leaves aren’t usually a sign of phosphorus deficiency, but instead an indicator that anthocyanins can help plants survive many environmental stresses.
My interview this week is with Cass Turnbull, founder of PlantAmnesty, a Seattle organization dedicated to “ending the senseless torture and mutilation of trees and shrubs.” … Continue reading this article “Podcast #7 – Better Red Than Dead”
The glorious Allium ‘Globemaster.’
Michelle and Laura B. nailed it, and Jennie had the correct genus.
A little taxonomic correction – it is NOT A. giganteum, as many catalogs and articles suggest, but rather a hybrid between A. macleanii and A. christophii; described by the breeder himself – Jan Bijl – in a 1990 issue of The Plantsman (vol. 12 pp 152-156). Unless I’ve totally messed up and this is ‘Gladiator,’ not ‘Globemaster.’ They’re quite similar.… Continue reading this article “You guessed it…”
There was a flurry of great posts this week; no way I’m competing with Linda’s trip to the fabulous garden of The Riz. So I’ll put up a quiz pic. Hopefully it will take you longer than 30 seconds to figure it out:
Eh? Eh? Family may be obvious, but…
School starts next week and so time is short, but I have a few quick thoughts to share with you before I get back to setting up class for next semester:
1. A class called Plant Production appears to be more attractive to students than a class called Nursery Management and Production — even though the concepts taught are essentially the same.
2. One of the greatest movies of all time, Caddyshack, includes a scene with milorganite. … Continue reading this article “Odds and Ends and Scrapple”
Forgive my tardy posting – I spent yesterday traveling from Indianapolis back to Seattle. I was in Indianapolis for the Garden Writers Association annual meeting and gave a talk on “evidence based garden information.” It was encouraging to see how many garden writers DO want reliable sources of good gardening science. And I got to meet Joseph Tychonievich, a frequent commenter on this blog and a PhD student at Michigan State.
Anyway, on to this week’s podcast.… Continue reading this article “Podcast #6 – Garden Hocus Pocus”
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.”
