If you follow this blog then you know that I write a lot about pesticides. They’re something that I enjoy reading about and studying. For whatever reason, I find them fascinating. That said, they can be some of the worst things for wildlife. But there are pesticides that are more “wildlife compatible” than others, so today I’m going to cover some of the worst pesticides that you can use in terms of wildlife, and some of the pesticides that might be more acceptable (though far from perfect).… Continue reading this article “Pesticides and Wildlife”

Want more bird visitors? Nonnative plants may be the answer
We’ve posted before about the native vs. nonnative conundrum, especially as it relates to invasive species. So let’s complicate the issue a bit more by considering how birds are affected by our landscape choices.
About 10 years ago my UW colleague Sarah Reichard and I collaborated on a literature review on the interaction between birds and non-native plants. While we know that invasive plants can displace native plants and create less biodiverse environments, the resulting impact on species like birds is not so cut and dried. … Continue reading this article “Want more bird visitors? Nonnative plants may be the answer”
The Garden Professors Go Wild!
It’s ‘Wildlife week’ on the Garden Professors. One of the most common questions that we get when speaking to garden groups is, “What can I do around my home to promote wildlife?” My stock answer used to be, “Throw a party!”, but only a handful of people ever got it so I’ve backed off of that one. Anyway, since the subject of gardening and wildlife comes up so often we’ve decided to dedicate a week to the topic.… Continue reading this article “The Garden Professors Go Wild!”
Big Trees for Crime Reduction
Like Linda, I believe that we don’t plant enough bare-root trees. Trees that are harvested and sold bare root tend to establish better and recover faster from transplant shock than trees sold in containers or as B&B (balled and burlapped) stock. But, in general, trees that are purchased in as bare-root stock are smaller than the other two styles, with B&B generally being the production method which yields the largest trees.
I disagree with Linda that, as a general rule, B&B stock should have its roots washed off prior to transplanting — I’ve done it and I’ve lost trees. … Continue reading this article “Big Trees for Crime Reduction”
What’s In A Name
Marketing is important if you want to sell something, but I have always been amazed at the different names that chemical companies have come up with for pesticides. Way back when, in the early 1900s and late 1800s insecticides were given soft, gentile names. Paris Green, London Purple, Bordeaux mix – really beautiful names that hint of worldly knowledge (for the most part they just indicate where the product was originally produced). In the mid-1900s names were more matter of fact: DDT, 2,4 D, 2,4,5 T — These names were indicative of the chemistry of the product being sold.… Continue reading this article “What’s In A Name”
Oh Deer! Part 2
Last week Holly and I extolled the virtues of our dogs for helping to keep our gardens and landscapes relatively deer-free even though we live in areas with high deer pressure. Of course, letting dogs roam your property is not an option for everyone. So what are some other options to keep deer from turning your garden into a salad buffet?

One of the most popular non-canine deer remedies is applying various deer repellants. … Continue reading this article “Oh Deer! Part 2”
When history and good stewardship collide
One of my colleagues emailed me a couple of pictures last week taken in Puyallup, WA. As you can see, there’s a trellis supporting a massive old trunk…
…and crown…
of an ancient Hedera helix ‘Baltica,’ a cultivar of English ivy.
For those of you not in Washington or Oregon state, English ivy is a designated noxious weed. Thousands of dollars and hours of labor are spent on removing this species from forested areas in Washington state, where it crowds out native species and increases tree failure simply through the weight of vegetation. … Continue reading this article “When history and good stewardship collide”
Confessions of a Weather Channel Addict
My name is Bert and I’m a Weather Channel junkie. It started innocently enough; sneaking an occasional peek at the local radar. Then I found myself sticking around for the next Local on the 8’s just for the smooth jazz. The progression from there was steady and predictable: Glued, trance-like, to the couch for re-runs of ‘Storm Stories’ and ‘When Weather Changed History’; setting my alarm 20 minutes early to catch ‘Wake up with Al’ so I could get my morning Stephanie Abrams fix. … Continue reading this article “Confessions of a Weather Channel Addict”
Can cultivars be considered native plants?
One of the questions that arise in discussing native plants is the question of whether ornamental cultivars (e.g., ‘October golory’ red maple) can or should be considered ‘native’. In short, my answer is ‘No.’
Here’s my rationale on this. First, when we think about natives we need to put political boundaries out of minds and think about ecosystems. Political boundaries – a ‘Michigan native’ or ‘an Oregon native’ – are meaningless in a biological context. What’s important is what ecosystem the plant occurs in naturally. … Continue reading this article “Can cultivars be considered native plants?”
The New Evidence Against Glyphosate
This past week Susan over at Garden Rant asked me about a paper which she had recently read which “proved” that Round-up caused birth defects. This study was interesting because it took embryos of chickens, exposed them to glyphosate (the active ingredient in Round-up) and then looked at the problems which the embryos had. Indeed, there were problems at concentrations of glyphosate much lower than what you’d see in normal agricultural applications. This is similar to other studies which “prove” how toxic glyphosate is which have been conducted over the years where various types of cells have been removed from human bodies, exposed to glyphosate, and then the resulting cellular damage has been taken as an indication that this herbicide is incredibly dangerous to us.… Continue reading this article “The New Evidence Against Glyphosate”
