Surviving the desert with beauty and efficiency

I’m away this week for an out-of-state seminar and a little annual leave.   Some of my favorite places to visit this time of year are the high deserts of California.  Today we hiked to Horse Thief Creek, a relatively easy trail in the Santa Rosa Wilderness.  It’s the perfect time of year to see the high desert in bloom, especially with last winter’s substantial rainfall.

In graduate school I became interested in environmental stress physiology, and I still am entranced by the plant kingdom’s ability to overcome nearly every environmental extreme on earth. … Continue reading this article “Surviving the desert with beauty and efficiency”

Products!

Just returned from a mega field trip across the state of Virginia with my Ornamental Plant Production & Marketing class. We toured major wholesale nurseries, greenhouses, and retail garden centers over the course of three days. The trip went well, I believe (university field trips are a considered a success if you return with the same number of students you left with).

One over-arching trend is, of course, that growers and retailers are going after the veg/fruit thing in a big way.… Continue reading this article “Products!”

Getting Loaded

Spring is off to a warm and fast start here in Michigan.  March was unseasonably warm and the past week or so has seen temperature 20 degrees above average or more.  Needless to say this is pushing all of our landscape trees and shrubs.  Forsythia and saucer magnolia are in full bloom, at least two weeks ahead of schedule.  The warm weather also has us scrambling to get some research projects in the ground as well.  … Continue reading this article “Getting Loaded”

Friday investigation – April Fools!

I didn’t exactly cheat on this one…but it was a mean trick nevertheless.

This is a contorted cultivar of Larix (can’t remember the exact name and I’m out of town this week), hence the twisty needles.  And indeed the tree is senescing.  The newer growth (the second flush of the season) just wasn’t as prepared for fall as the older growth, which is yellowing naturally.  So everything is just peachy with this tree.

Just goes to show you how important it is to know all the details when doing distance diagnosis!… Continue reading this article “Friday investigation – April Fools!”

Friday investigation

Today I’ve attached a photo of a conifer displaying two symptoms:  chlorosis of the older needles and a twisted appearance:

What do you think are the causes of these symptoms?  Answers on Monday!

Haber and Bosch

There are people who are fascinated by plants and people who are fascinated by the science of growing plants.  While I love plants I must confess that I consider myself to reside more firmly in the latter group that the former.  I do love to see the beautiful flowers on an apple tree in the spring, but I’m more fascinated by the nitrogen, phosphorus, potassium and other elements that the tree obtains from the soil.  I like to contemplate the complex ecosystem that surrounds the tree, including the tree’s pests and the possible things that we can do to protect the tree from pests. … Continue reading this article “Haber and Bosch”
