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”

Where the Money Comes From

After reading Linda’s excellent post yesterday I got to thinking about all of the discussions I have had over the years with people who didn’t know or understand where we (and by we, I mean my research group) got the money to do the work which we do.  Oh, they thought they knew, but they were usually way, way off.  So here I’m going to give you a terribly over-simplified version of the types of money that a professor can get to conduct the research that they want to conduct.… Continue reading this article “Where the Money Comes From”

Happy Days

Today is such a good day.  Really good.  Almost as good as my wedding day and the birth of my kids good.  Better than the Eagles won the Superbowl good (I’m a big Philadelphia Eagles football fan — Mike Vick and his transgressions aside of course).

Just for today I don’t care much about the arguments for or against organics, natives or even my favorite topic, pesticides.

What’s the news you ask?

Peanuts.  Hot Boiled Peanut.… Continue reading this article “Happy Days”

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”

How to Kill Buckthorn

Last year we completed a small research study on how to kill buckthorn.  If you live in the upper Midwest then you’re familiar with this plant as a shrub which has escaped cultivation, been spread by birds, and generally made a nuisance of itself, particularly at the edges of forested land.

Buckthorn is notoriously difficult to kill after it gets more than about a foot high.  It laughs at single applications of roundup. If it’s pulled out of the ground any roots that don’t come with it have a good chance of sprouting shoots themselves, and it seems to enjoy being treated with organic herbicides like vinegar. … Continue reading this article “How to Kill Buckthorn”

Are Fertilizer and Insecticide Spikes a Good Idea?

One of the products that I often hear gardeners raving about are their fertilizer / pesticide combination spikes which are supposed to not only feed your plants, but also kill all of the insects which attack them.  I, personally, have not used these products, but I’m generally the kind of person who says “If it works for you then keep using it”.  Still, these spikes bug me a little.  Here’s why.

First of all I should point out that I’m not opposed to fertilizer spikes by themselves. … Continue reading this article “Are Fertilizer and Insecticide Spikes a Good Idea?”

My Long Suffering Basil

Sometimes I am not such a good garden professor.  That’s because, when I get home, I sometimes (OK — often) don’t give my plants the attention they need.  It’s also because, when we leave for vacation, I often forget to tell whoever is watching the animals to keep their eyes on the plants too.  Now, really, you would think that someone who saw a plant on the back porch in full wilt would think “Hey, Maybe I should water that!” … Continue reading this article “My Long Suffering Basil”

Why I like science (our visiting professor returns)

I like science.  I see it as a way to figure things out.  It creates a combination of a) things we’re pretty sure of (facts about the shape of DNA, the optimum pH for certain plant species, and theories consistent with such facts, for example) and importantly, b) questions we can ask next.  When research is designed to answer those new questions, the results will either support the things we’re pretty sure of and lead to an expanded understanding and new questions, or they won’t support what we thought we knew and the results will lead to a different understanding and new questions. … Continue reading this article “Why I like science (our visiting professor returns)”

Dog Spots

There is a general misunderstanding among the gardening (and yard owning) community about dog spots.  It seems that some people believe that dog spots occur because of a high or low pH or because of some sort of poison in a dog’s urine, but that really isn’t the case at all.  Dog spots occur because of something that I pointed out a few weeks ago in another post.  Urine contains a lot of nitrogen.  When a dog pees on your lawn that extra nitrogen isn’t used and so ends up being poisonous to the grass which is peed upon. … Continue reading this article “Dog Spots”
