You got it! Horsetails don’t produce pollen, and those airborne particles are spores. Primitive plants such as mosses, ferns, and horsetails don’t have the same reproductive structures as flowering plants and conifers. Instead of producing seeds, they form tiny, windborne spores that can be mistaken for pollen.

My sharp-eyed husband spotted this on the front page of yesterday’s paper:
Answer Monday!
Rotenone is an organic insecticide that has been voluntarily withdrawn by its manufacturer because it’s quite toxic, it’s dangerous to the environment, and there is some evidence that it causes Parkinson’s disease. And there are safer choices. For my post today I was thinking of posting about all of the places I could still buy rotenone, but after doing a web search I couldn’t find many – and most of the places I found to purchase it don’t really have it (I don’t think) – they’re just old pages that weren’t taken down.… Continue reading this article “Rotenone in Dog Medication”
With 60+ newbies in our local beginner beekeeping class, we can safely say that beekeeping is enjoying a surge of popularity. The president of our area beekeeping association is bringing 150 packages of bees up from Georgia next Thursday; all are pre-sold to members. That’s about 1.8 million honeybees (includes one queen per package). An additional 50 packages will arrive the following week for close to 3 million bees. Wow.
I’ve planned to take the afternoon off (Beefest!)… Continue reading this article “Bees bees bees!”
It’s spring, and everyone is itching to buy stuff at the nursery. I’m there too, with my camera as well as my wallet. I thought you might enjoy some of my “Things to avoid when you are plant shopping” collection:
These are called “Serpentine.” I call them unnatural. Like foot-binding.
Rootstock revolt. The surest way to kill off your grafted scion.
A botanical bow? Or a horticultural harp?
And check out the pot! If there’s enough root mass in there to crack the pot, you can bet it’s long past its potting up date.… Continue reading this article “WOW returns! (Why oh why?)”
Despite Linda’s assertion to the contrary, I was not cow-tipping nor was I sampling micro-brews last week when I missed my regular post. As usual, the beginning of spring is a busy time on the research side of my appointment. This past week we began setting up for a major new project. The goal of our newest study is to look at physiological traits of street trees that may enable them to better withstand future climate change. … Continue reading this article “Here we go again…”
First, let me give a blanket apology for all of us GPs – this is the first time ever all four of us have NOT posted in the same week. I’m on the road this week with my high schooler checking out colleges, and I think the other three are out drinking beer and tipping cows somewhere. So our visiting GP veggie specialist extraordinaire has graciously stepped in to answer a reader’s question about the apparent decline in vegetable nutrition. … Continue reading this article “Our visiting professor takes on veggie nutrition”
When my day/week/month is going to heck in a handbasket, when faced with yet another impending-doom deadline, when the pile of folders on my desk grows so tall I can barely see over it… when the going gets tough, a little bit of cute can go a loooong way.
So here ’tis:
Thalictrum thalictroides ‘Pink Pearl’
Not many plants fall into the "cute as a kitten/puppy/baby duck OMG" category, but this is one of them.
Used to be Anemonella thalictroides, but recent molecular "fingerprinting" puts it into the (rather redundant) genus Thalictrum. … Continue reading this article “Cute plant alert!”
I like to say that my taste in music is eclectic, but it’s not really true. I like music that is known as classic rock (60s – 80s rock once known as pop) and I like music known as "alternative" (really a meaningless term — but I don’t invent the labels). The one band that I love who might be considered completely out of the mainstream is Rasputina — a cello based group who sing about many things, including history. … Continue reading this article “Why I Don’t Worry Too Much about Trees Dying after Late Frosts”
A few weeks ago an attendee at one of my seminars asked me about bokashi composting. It’s a term I hadn’t heard before, so I promised to look into it (and the science behind it, of course). I haven’t had a chance to do much more than a cursory analysis, but even that has proven interesting.
For those of you who, like me, had never heard of bokashi, it’s a composting technique that utilizes Effective Microorganisms® as a way of creating a “positive” compost product using “positive” microorganisms. … Continue reading this article “Bokashi composting and Effective Microorganisms® – a quick analysis”
