Here’s a good piece of gardening advice. If someone says that they have a ginormous amount of a certain plant and they want to give you some, RUN AWAY.
With few exceptions, if a plant has taken over that person’s garden, it will take over yours too because it is evil—or invasive—whatever you want to call it. It doesn’t care. In fact, it may employ trickery to try to get you to take it home and plant it.
That’s definitely the case with creeping bellflower (Campanula rapunculoides). Even if you don’t know the name, you’ve probably noticed this horrible-to-the-core plant because it’s tall and showy with pretty purple bell-shaped flowers. It’s also everywhere that it can possibly get a foothold, especially this year because the plant likes moist soil and we’ve had so much rain.
Native to Europe, creeping bellflower was actually introduced to North America as a lovely new ornamental (I’m not sure when) and it quickly became popular with unsuspecting gardeners. In fact, I frequently see this plant on tables at plant sales or potted up and sitting on the sidewalk outside of people’s houses with a “Free” sign on it. (To be fair, it isn’t invasive everywhere like it is here in the Midwest.) The problem is, creeping bellflower has a very strong and extensive root system so it spreads quickly and will easily take over your garden and choke out other plants.
It’s also hard to get rid of. I’m not a big fan of chemicals, and they don’t work very well on bellflower anyway, so I’m going to explain two non-chemical ways to kill this miserable plant. Basically, you can dig it out or smother it. I often do some of both. No matter which way you go, it will take years to eradicate this flower-weed creature. Or, like me, you may just get to the point where it’s at least tamed enough that you can cope with ripping out a few of them each year.Read More»
I generally try to avoid writing a lot about the same issue for fear of boring people to death or seeming like a nutter who can’t stop ranting about one thing or another. In the case of neonicotinoid pesticides, though, I’ve received so many calls and emails on this topic since I started writing about it a few months back, I feel like updates are wanted and needed. So I’m going to go with that feeling and tell you more about what I’ve learned lately in hopes that this will help answer some questions you may have now that you’ve likely learned more about this issue too.
First, here’s a quick recap for those who don’t yet know about neonicotinoids. Neonics, as they are often called, are a class of pesticides that have been linked to the decline of bees, particularly honeybees, over the last decade. Because they are safer for humans than some other pesticides, neonics have become widely used in the nursery trade as a pre-treatment for annuals, perennials, shrubs and trees. They are also found in many of the common pest control products gardeners buy off the shelf and use every day for everything from Japanese beetles to emerald ash borer. (Neonic pesticides include: imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam.)
Now that studies have shown that small amounts of neonics can harm bees feeding on the pollen and nectar of treated plants while larger doses can kill, more and more gardeners are making it a point to stop using products that contain neonics and to shop for plants that haven’t been treated with the pesticides. I’ve heard from a lot of people who have called, visited and emailed garden centers and nurseries locally and nationally asking about the use of neonics.
Stories vary widely with some places eagerly sharing their plans to discontinue their own use of neonics and to seek out suppliers who will do the same. But I’ve also heard reports of a fair amount of denial and defensiveness. What you need to know is that it isn’t enough for a retailer to say THEY are not using neonics any longer on the plants that they grow. You also need to know whether the plants they get from outside suppliers are neonic free. Getting that information will take willingness and time on the part of the nursery and from what I’m hearing, it’s clear that not everyone is putting in the effort.Read More»
I just want to take a minute to update my recent post, “In Search of Plants That Won’t Harm Bees.” I’ve now had the chance to talk with Bachman’s CEO, Dale Bachman, as well as John Daniels, Bachman’s vice president of production, about how the company is dealing with neonicotinoids (neonics), a class of pesticides that is harming bees.
As of 2014, while various entities continue to research the role neonicotinoids play in the decline of bees, Bachman’s has decided to take the “precautionary step” of removing all neonicotinoid products for home use from their shelves. That includes imidacloprid, a popular neonicotinoid pesticide used for all sorts of things like rose and lawn care, as well as to protect trees from emerald ash borer. (Of course, homeowners can still buy these products elsewhere and hire professionals who use imidacloprid to treat ash trees.)
They have also stopped using neonics in the production of Bachman’s-grown nursery stock and outdoor plants, which means most of their shrub roses and perennials will be neonic-free along with some annuals. As for plants from other suppliers, they are currently talking with vendors about discontinuing the use of neonics and Dale and John says the outcome may cause them to rethink some of their suppliers. Even as they said that, though, they stressed that the neonics issue is much more complicated than it may seem — a fact that becomes more and more clear to me as I interview people on this topic.
For example, in many instances neonics and other pesticides are used in compliance with regulations regarding moving plants and the potentially invasive pests they may harbor across state lines. In the case of large-scale suppliers, discontinuing the use of neonics will mean switching to other pesticides that will come with their own problems and consequences. For now, shoppers looking for neonic-free plants at Bachman’s should seek out a salesperson for help locating plants the company has grown since implementing their new policy.
Take a deep breath. Buying plants at places that many of us like to shop is going to take more work and patience than usual if we want to help bees. If you start to feel frustrated about the slow pace of change, remember that we are part of the problem. Gardeners have come to expect perfect plants on store shelves, so every entity in the plant supply chain has done everything in its power to kill every bug and wipe out every disease imaginable to make us happy. Moving away from chemical treatments that harm people, pollinators and the planet will be costly and difficult for those who care enough to do so. And we’re going to need to learn to live with more mites, aphids and other things than we’re used to. Who’s in?
Spring is almost, kind of, possibly (but don’t get your hopes up yet) in the air here in Minnesota. So let’s buck up and talk about gardening!
First, if you’re a local gardener and you’ve ever wanted to try straw bale gardening—or find out what you’re doing wrong while straw bale gardening—head over to the State Fair grounds on Saturday, April 26, for Straw Bale Garden Education Day.
Joel Karsten, author of Straw Bale Gardens: The Breakthrough Method for Growing Vegetables Anywhere, Earlier and with No Weeding, will be teaching seminars and selling and signing books at this free event that runs from 9 a.m. to 2 p.m. in the north parking lot off Snelling Avenue. (Check out this blog post I wrote last year about Joel to find out more about him and straw bale gardening.)
If you’ve got room in your car, Otten Bros. Garden Center will be on site for Straw Bale Education day selling everything you need to start your own straw bale garden this season, including straw bales. Free coffee and cookies will be available as long as they last.
Want to win a free copy of Joel’s book? Great! I’ve got two to give away this week. To win, just comment on this post with a few sentences about why you’d like to try straw bale gardening or, if you’ve already tried it, how things went for you. Winners will be randomly chosen since I can’t think of a better way to do that sort of thing, and I’ll be in touch to your addresses.
Macy’s Flower Show
Every year, just when Minnesotans need it most, Macy’s Flower Show opens and thousands of us stumble in, blinking in disbelief after having seen nothing but white for so long, eager for the chance to gaze at plants and smell fragrant blooms and dirt again. This year’s show ended last Sunday, April 6, and if you missed it, make a note in your calendar right now so you’re sure to see it next March.
Yes, the show does take place in the department store’s 8th-floor auditorium. But if you’re inclined to diss this event because it’s in a store, I’m here to tell you that they start in January and transform that auditorium into something truly magical every year. This year’s theme was The Secret Garden and, as always, Bachman’s designed the show’s many displays, which featured flowers, plants and trees from around the world—many of them hardy in Minnesota.Read More»
In the midst of the worst winter—ever—it’s hard to think about flowers, I know. But this time of year, I normally order a few plants for spring delivery from catalogs and I’m having to spend a lot more time on that than usual because I want to make sure that the flowers I’m ordering aren’t going to kill the bees that visit my gardens. By now you’ve probably heard that many of the pollinator-friendly plants and flowers that we’ve been filling our gardens with over the last few years may actually be harming, and even killing, bees. The culprit, many scientists and researchers believe, are neonicotinoid pesticides. Widely used in lawn fertilizers and on crops and nursery plants, neonicotinoids (commonly called neonics) came on the market in the 1990s and are chemically related to nicotine.
Marketed as safer for humans than other pesticides, neonics are now thought to be at least in part responsible for declining bee populations all over the world. Let me explain why. Like all systemic pesticides, neonics are absorbed by plants after being applied to the leaves, seeds or even soil. When bees and other pollinators feed on the leaves, flowers and pollen of plants treated with neonics, they ingest a “dose” of the insecticide.
Though the makers of these pesticides contend that the amount ingested by insects, including bees, is not enough to kill them, entomologists who study bees believe otherwise. Neonicotinoids are neuroactive, meaning they block connections in the brain. Over the last several years, studies have shown that even after ingesting small amounts of neonics, bees can become confused to the point of being unable to identify food sources. Some even forget how to find their way back to the hive. Over time, without food from the hive’s forages, colonies starve and collapse.
Vera Krischik, an entomologist at the University of Minnesota, has been studying the effects of insecticide on bees for several years. She has found that large doses of neonics can kill bees, sometimes moments after they feed on a treated plant. Where are they getting these large doses of neonicotinoid pesticides? Possibly, my garden, I hate to say; or maybe yours, or your neighbor’s. That’s because it is legal to treat ornamental plants with much higher levels of neonicotinoids than are acceptable for use on agricultural crops like corn and soybeans. And because pre-treatment of nursery plants is so common these days, it’s very likely that most of us have brought home some of these plants in the last few years without realizing the harm they could be doing.
What Can Gardeners Do?
So what can we do now? Well, that’s going to take a bit of work on our part. Concern over whether neonicotinoids are harming bees is not new, and Krischik is just one of many researchers across the country. and the world, who have spoken out about the problem. As a result, some European countries have restricted or banned some neonicotinoids.
But, as is usually the case, our U.S. Environmental Protection Agency has opted to take a wait-and-see approach and has decided to look at the insecticide as part of a standard registration review. That could take years—years that bees don’t have. Though it is good news that the Minnesota Department of Agriculture and the Department of Natural Resources seem to have taken the issue more seriously since the start of the year.
For now, fellow gardeners, help must come from us, so we need to do all we can to keep neonics out of our gardens. That means growing some of our plants ourselves using seeds collected from plants we know to be untreated or purchased from retailers who don’t sell pre-treated seeds such as Seed Savers Exchange, Baker Creek Heirloom Seeds and Renee’s Garden Seeds.
Shopping for plants will be trickier and in some cases, more expensive. Home Depot and Lowes may offer lower prices on ornamental plants, but so far Home Depot has indicated that they plan to continue selling plants treated with neonics until they can work with suppliers to find an alternative insecticide. I don’t know about Lowes, but I imagine that selling far fewer plants to gardeners who won’t buy anything treated with neonics might speed talks up a bit.
Before buying plants from any seller, ask them whether they use neonics or buy plants treated with them. To help, I made some calls for this article to see how various growers and garden centers are dealing with this issue. Glacial Ridge Growers in Glenwood, Minnesota, sells native plants free of neonics. Bachman’s, Gertens and Menards didn’t return calls before my deadline, so you’ll need to ask them yourselves. Mother Earth Gardens says they don’t sell any flowering, edible or fruiting plants treated with neonics, though they do carry a few non-flowering trees that have been treated with the pesticides.
Scott Endres, co-owner of Minneapolis’ Tangletown Gardens, told me that though he can’t guarantee that every single plant they sell is neonic-free, almost every single plant is neonic-free because they grow the majority of them themselves and know exactly how they are produced. When they do buy something they want to carry but don’t grow, he says they buy from reputable growers they trust, so consumers can feel confident buying plants from them. Scott also said that he thinks it’s “awesome” that more and more gardeners are insisting on plants grown “with organic principles that support a sustainable product and the earth.” He believes that people’s awareness is already creating demand that is pushing companies to think more closely about their practices. I couldn’t agree more.
Yes, it’s me again, nattering on about the cold, cold, horribly cold winter we’re having here in Minnesota—and a lot of other places too, I know. But, honestly, most of you in other states will be warm again far sooner than we will here in the tundra. So I feel entitled to go on about this a bit more and if you don’t agree, please don’t send me another email telling me that if I don’t love it in Minnesota, I should move. Move where? In with you? Awesome!
Anyway, as I was saying, a local meteorologist wrote the other day that Minnesotans are experiencing the coldest winter in 33 years. I didn’t live here then, but I believe him. Minnesotans are tough, but it’s been far below zero with mind-boggling wind chills for a long time now. Kids are bored at home because schools have been closed repeatedly. Parents are using up precious vacation days staying home with bored kids. And bored dogs wish they could go outside, but they can’t stand how cold their paws get, even with those awful booties that they hate.
We are a stir-crazy lot, motivated to do little more than lie on the couch and drink and order takeout while watching movie after movie. Or is that just me? BTW, I would highly recommend Seven Psychopaths and The Heat, but I thought Iron Man 3 was kind of meh even though I loved the first two.
What does this have to do with gardening? you wonder. Well, in an effort to stop spending so much time eating, drinking and watching movies, I recently tried focusing on spring to brighten my mood and, by golly, it worked! In addition to looking at a bunch of the garden-related photos I took last season, I also spent a few hours going through all of the seed and plant catalogs that have piled up on my living room coffee table. That was fun, especially because our sweet dog, Lily, helped by napping on me the whole time.
So if you’re bored and freezing and in need of some good cheer, I’ve posted a few photos below in the hope that they help a bit. And if you haven’t already started looking at your seed and plant catalogs, give it a go. I bet it will make you feel better to start thinking about what you’ll plant in just a few weeks or months, depending on where your live. I especially love Renee’s Garden, Baker Creek Heirloom Seeds (their catalog is a work of art—just ignore the religious quotes that pop up now and then), Seed Savers Exchange, Fedco Seeds, Prairie Moon Nursery and Territorial Seed Company.
That’s it for now. Hang in there. Spring is really, seriously, surely on the way.
