Roadside Rest: Living in the Moment

One of the things I ask my Sustainable Landscape Maintenance students at the end of the semester is to expound upon 10 Things They Learned in class. Most of these are the core of the course: including plant selection and knowledge, plant pest, plant maintenance, invasive species examples. Pete Grantham of Akron though, added:

 

  I learn from you so much about living in the moment, talked to me about your hitchhiking [the old days] and how you think it’s fun to run out of gas. These moments that others would consider worrisome are...

Crabapples in China

  One of the more pleasant e-mails I have received in recent memory was from my friend and colleague Dr. Ling Guo of the Beijing Botanic Gardens. It read: “Jim, would you please come to Beijing for Crabapple Conference in April 14-19 for one hour talk. All expenses paid.  Hmm, let’s see. Yes!  Fortunately, for my talkative nature it turned out to be a bit more than that one hour talk, not including the translations, but what a deal.

Diagnostic Double-Take: Scorch or Scab

  Last Friday, outside our bank in Orrville, Ohio, I espied a crabapple tree with a carpet of brown leaves underneath the tree. On first glance, I imagined this to be due to leaf scorch and then leaf drop due to recent dry weather. After all, we are almost eight inches below normal over the past three months in many northeast Ohio areas. Made sense. I was simply following Question #4 of the 20 Questions of Plant Diagnostics: What Do You See That Looks Abnormal?

Crabapple Scab in Ohio

Apple scab disease, caused by the fungus Venturia inaequalis, is a common problem resulting in major aesthetic damage to many crabapple types (taxa). However, there is a tremendous range of susceptibility of these crabapple taxa to scab, and this can make all the difference to a landscape designer, a nurseryman, a homeowner, a garden center professional or Master Gardener volunteer making recommendations for plant selection. Got leaves, got ugly leaves, got beautiful leaves – all are options.

 

This is why the International Ornamental Crabapple Society has...

Fireblight, Crabapple, Crablandia. One Strike...

We were out in our Crablandia plots at the Secrest Arboretum of OSU’s Ohio Agricultural Research and Development Center in Wooster today. One mission was to check for bacterial fireblight disease on the 76 crabapple taxa in our replicated, randomized plot. This spring we had heard of and seen some fireblight, on crabapples and other related rosaceous plants such as pears elsewhere, and we have susceptible crabapples in the trials so why not here? Yet, cultivar after cultivar, early blooming and late blooming types - no fireblight. Wait, wait, we see one shoot with the tell-tale shepherd’s...
