Bachman’s Is Moving Away From Neonics That Harm Bees

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?

In Search Of Plants That Won’t Harm Bees

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.


Dreaming of Spring

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!

At least the fern frost continues to put on a show on the bathroom window.

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.

Lily doesn’t much care that she’s making it hard for me to take notes on the vegetable seeds that I want to order for next year.

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.

Our friend Kendall makes these lovely succulent frames to hang on her patio in San Francisco.

A fabulous giant pumpkin at last year’s Minnesota State Fair.

I like the way Tangletown Gardens planted this container by grouping plants en masse.

Gorgeous seeds that I harvested from a plant on my boulevard. I planted it, but forgot what it is. Can you guess from looking at these seeds?

Yes, we WILL be out shopping for plants again soon.

Note the ridiculously tall Kentucky Wonder pole beans in my vegetable garden last year. Insanely tall, produced about 40 beans in the last couple of weeks of the season. What gives?

This was one of several little water gardens I saw at a house on one of the garden tours last year.

Doesn’t all that green make you feel better already? Check out that variegated Solomon’s seal.

What a great lesson in how to combine different colors and textures. Again, it is the work of Tangletown Gardens.


That’s it for now. Hang in there. Spring is really, seriously, surely on the way.

Experimenting With Grafted Tomatoes

Grafted tomatoes, especially heirlooms, were really hot this year. Why graft heirlooms? Well, the reasoning is that by grafting the heirlooms we love—Brandywines, Green Zebras, Cherokee Purples, Mortgage Lifters—to a rootstock that’s got, say, great drought tolerance or disease resistance, you get what amounts to a super heirloom.

The strategy isn’t new. Apple and grape varieties have been produced successfully on desirable rootstock for ages. But this is the first time that home gardeners in the U.S. are really starting to see grafted vegetables, including eggplants, peppers, cucumbers and watermelon, becoming increasingly available at the retail level. Territorial Seed Company, Johnny’s Selected Seeds and White Flower Farm are just a few of the places where you’ll find grafted vegetables.

Though I admit that there can be problems with heirlooms tomatoes, I go out of my way to plant them. So I like the idea of making them more viable and widely available. Like a lot of gardeners, I feel strongly about the importance of including heirlooms of all types in the garden and, on the whole, I think heirloom tomatoes taste better than their hybrid peers, which often have tough skins and bland flavor. (Some of my favorite heirlooms are Black Krim, Green Zebra, Stupice and Sweet Million, though I always, always, always plant Sungolds, those out-of-this-world hybrid, yellow cherry tomatoes.)

Indigo Rose tomatoes were gorgeous, but didn’t taste like much.


More Indigo Rose porn.

Still, I’m always up for trying something new. So I was happy to get a surprise box of grafted tomato seedling samples (some heirlooms, some not) from Mighty ‘Mato early in the season. Having a limited amount of sun to work with, I kept two for myself, an Indigo Rose and a Brandywine, and gave the others to master gardener friends to plant and report back on. During the season, I also talked with more MGs and garden writers who were experimenting with grafted tomatoes. The outcome? Impressions were mixed.

Take Indigo Rose, for example. I had been wanting to try Indigo Rose, which was introduced by Oregon State University in 2012. Their goal was to produce a tomato with high levels of antioxidants. I wanted to grow the tomato because I fell for the weird looking purple-black fruit. I planted both grafted and ungrafted Indigo Rose tomatoes so I could compare the two (and so I could justify planting way too many tomatoes, like I always do).

Sadly, though they both produced an absurd amount of fruit all summer long, I didn’t like either of them, mainly because the tomatoes took FOREVER to ripen and when they finally did, they tasted bland and watery. Also of note was the fact that I honestly noticed no difference between the grafted plants and the ungrafted plants. Most of the gardeners I’ve talked to had similar experiences with Indigo Rose, though I will say that a few thought they were tastier than I did.

Grafted Indigo Ruby tomatoes got rave reviews from gardeners.

On the plus side, my friend, Deb, loved Mighty ‘Mato’s grafted Indigo Ruby, a cross between Indigo Rose and a cherry tomato. The plant grew well, was free of disease and produced very tasty tomatoes all season. I heard rave reviews from other gardeners, too, though I don’t know how they compared to ungrafted Indigo Ruby.

As for grafted Brandywine tomatoes, by all accounts, including mine, the grafted plants didn’t do as well as the heirlooms usually do on their own. I did hear lots of good things about grafted Legend tomatoes—great taste, good disease resistance and a LOT of tomatoes.

What does all of this mean? Well, at this point, I’m not ready to say that grafted tomatoes aren’t worth the price, which is steep compared to regular tomatoes, hybrids and heirlooms. But I’m not ready to sing their praises either. I’ll plant a couple more varieties next summer and report back on how things go. If you try grafted tomatoes, please let me know about your experiences. I’ll pass that information on so we can all compare notes.

Down With Gardening Snobbery

As a garden writer, I read a lot of gardening blogs and articles by other writers and landscape designers and I have to say, I’m finding them increasingly annoying and depressing. So much judgment and negativity—who died and made us the arbiters of all things right and tasteful?

When I’ve finished sipping tea from my golden cup, I shall tell you all what to plant in your gardens.

Without naming the writer and being a jerk when I’m trying to write about why it’s important to not be a jerk, let me just say that recently I read a blog post that pushed me over the edge. It was a short piece, posted by a writer who had a day off so she rented a bike in a nearby town and peddled around looking at gardens.

It was a beautiful blue-sky day, but she really couldn’t enjoy it because most of the homes she biked past were landscaped with predictable perennials, particularly KnockOut® roses and catmint (Nepeta). The fact that most of the roses were RED only accentuated the humdrum nature of the plants in her mind, and she posted a few pictures to bolster her point with “sophisticated” readers like us. Ugh. How can this sort of thing be helpful to anyone?

What’s so bad about KnockOut roses, anyway?

Sure, experienced gardeners or those with the good fortune to have an impermeable force field of self-esteem might read snobby comments like that and think: “To hell with her, I love my KnockOut roses.” But for many mortals trying to garden, it’s no fun to read something written by someone who is supposedly in the know that basically says you have bad taste if you plant certain things (or allow them to be planted by a landscaper) and you ought to know better. This kind of senseless garden bullying isn’t helpful or inspiring and needs to stop.

A Matter of Taste

I will confess right now that I am guilty of garden snobbery. I have written disparaging things about annual geraniums, dusty miller and other plants I don’t like. Thinking about it now, I can’t imagine how I ever thought that might be useful to anyone. Please accept my sincere apology for behaving like such a self-important turd.

But don’t get me wrong. I’m not saying that garden writers should only write nice things about plants. On the contrary, plants that perform poorly are absolutely fair game. It’s our job to spill the beans on crappy plants that don’t bloom well, fail to be as hardy as advertised or are riddled with diseases they’re supposed to be able to resist. And there’s nothing wrong with pointing out that certain plants are being used an awful lot and suggesting alternatives. That’s information that people can use. But slamming plants based on personal preference, or nattering on about how sophisticated gardeners would never have this or that “over-planted” plant in their gardens, is on par with shaming high school classmates over their choice of jeans.

I like our crowded gardens, but not this weird lens filter that makes the world look as if we’ve smeared Vaseline on everything. Gross.

Let’s face it. Whether you’re a professional or a novice, when it comes right down to it, plant picks and gardening styles are always about personal taste. Like most gardeners, I plant what I like, and what is given to me and what I find by the side of the road with a “Free” sign on it. I know and respect many local landscape designers, and I do follow some of their advice, but I don’t want to hire one of them to reimagine my yard for me. Then, I would be living with their taste, not mine. I like the crowded, overgrown gardens I have imagined for myself and I ignore the finger-waggers who question my taste level. You should too.

A slightly different version of this post appeared recently in Northern Gardener magazine.


Garden Tour Highlights

As you might have already guessed from the infrequency of my posts lately, the hardest thing about being a garden blogger is actually sitting down to write something in the summer. Winter is no problem. If you’re not into winter sports (and I am most definitely not) there’s nothing else to do here in Minnesota when it’s crazy-ass cold. But during our reasonably nice five months of each year, it’s hard not to spend every extra moment outdoors. Lately, I’ve been going to every garden tour I can find, large and small, and I’ve seen some beautiful, odd, innovative, lovingly tended and over-the-top landscapes. So I thought I’d share some photos. Here goes:

This year’s Tangletown Garden Tour, hosted by local Tangletown Gardens, included a stop at co-owner Scott Endres’ house, which showcased his design sensibilities and penchant for using unusual and colorful plants in fun and elegant ways.

The front porch—


And now the backyard— 

Okay, so this wasn’t on any tour. But my friend Kathleen and I saw it on the way to the tour, so here it is. Wow!

A few pretty plant combos.

Photos just can’t do justice to a garden we saw in Highland Park. The couple has been gardening on four city lots for more than 40 years and their gardens are clearly tended with loving care. Vegetables, perennials, a formal area with boxwood hedges and a gorgeous wisteria archway—it was breathtaking.

New Plants for 2013

I’m late, late, late with a post on new plants coming out this year. Sorry about that. It keeps slipping my mind because it’s still quite cold and rainy here in Minnesota even though we’re well into June now, so going to the garden center hasn’t been high on my list. I do think I’ll go this weekend, though, and here are some of the new things this year that I’m planning to try if I can find them.

Oso Happy® Smoothie Rose (Rosa Oso Happy Smoothie ‘Zlesak Poly3’ PPAF)

Bred by David Zlesak, a Minnesota-based plant breeder, hort professor and all around wonderful guy, Oso Happy Smoothie almost seems too good to be true. But it isn’t, and I know because I’m one of the lucky writers who got to test this Proven Winners introduction in my gardens last summer. Hardy, THORNLESS and resistant to black spot, this diminutive rose grows to 3 feet tall and offers up bright pink single blooms from June until frost. Mine still looked fantastic at Halloween, planted in a protected spot near the house. Sadly, the rabbits ate it over the winter and now I need a new one that I will definitely fence this fall. Full sun. Zones 4 – 9.

Oso Happy® Smoothie Rose

Brunnera ‘Sea Heart’ (Brunnera macrophylla ‘Sea Heart’)

Plants Nouveau is behind this pretty new brunnera, which their website touts as “Like ‘Jack Frost’, but on steroids’, which sounds creepy, honestly. But they go on to explain that in a side-by-side test with ‘Jack Frost’, ‘Sea Hart’ flowered longer and better handled the heat and humidity. Sounds good, and the pink and blue blooms look lovely, too. I’ll always make room for brunneras. Full sun to full shade. Zones 4 to 8.

Brunnera Sea Heart

Heuchera Little Cutie™ Series

Terra Nova Nurseries introduced its mini coral bells series, Little Cutie, exclusively last summer. So I’m calling these plants new in 2013 because they are now much more widely available. The series includes seven petite, new heucheras, all bred for their outstanding colors, including ‘Blondie’, ‘Coco’, ‘Frost’, Ginger Snap’, Peppermint’, ‘Sugar Berry’ and ‘Sweet Tart’. Drought-tolerant and easy going as long as they’re planted in well-drained soil, these Little Cutie coral bells look best when grown in rock gardens or spots where they won’t get lost among larger plants. They also make great container plants, providing you heel them in before winter. Full sun to part shade. Zones 4 to 9 (depending on the variety).

Heuchera ‘Sweet Tart’


Heuchera ‘Coco’

 Hibiscus ‘Midnight Marvel’

I added hardy hibiscus to my gardens a few years back and they never fail to stop passersby who want to know, “What are those beautiful, exotic-looking plants?” ‘Midnight Marvel’ from Walters Gardens kicks things up a notch with this hibiscus, which grows to 48 inches tall and offers dark black-burgundy foliage with gorgeous red blooms that last from mid-summer to fall. Full sun. Zones 4 – 9.

Hibiscus ‘Midnight Marvel’


Wisteria ‘Betty Matthews’ (Wisteria macrostachya ‘Betty Matthews’ Summer Cascade)

I stupidly bought a Japanese wisteria years ago that never blooms and will likely never, ever bloom in our climate. So I’m going to euthanize the poor thing in a couple of weeks and replace it with this new variety from Bailey Nursery. Touted as being fragrant and more reliably cold hardy than other wisterias, ‘Betty Mathews’ has showy, dark-lavender blooms that are said to appear on new growth in early June. Once the flowers fade, cool-looking seedpods form in late summer and last into winter. Heck, I’ll try it. Full sun. Zones 4 – 8.

Wisteria ‘Betty Matthews’



What is ‘Safe’ Compost?

A few weeks back I did a short presentation in Pine City, Minn., on how to build good, healthy soil, and a woman in the audience asked: “How do I know if the compost I’m using is safe?”

I’ve been wondering that same thing, I told her, explaining that I’ve been researching the topic so I have some answers, but many more questions, too. This prompted more people to weigh in on the subject, asking: Was it important to use organic compost, especially when growing edibles? How do you know that even organic compost is safe?

Does composted manure from conventional farmers contain pesticide and herbicide residue that could cause problems in their gardens? Should you have compost tested to find out what’s in it before you use it on food crops and, if so, where? And what about GMOs? Is it safe to use composted manure produced on conventional farms on which cows eat things like Monsanto’s genetically modified Roundup Ready corn and alfalfa?

Complex questions like these are difficult to answer definitively for a lot of reasons. Sometimes, there aren’t many studies, if any, on a particular topic. Or maybe there are numerous seemingly reputable studies, but many of them conflict with one another. For example, as a journalist who interviews people for a living, I can tell you that for every scientist I’ve talked to who dismisses the French study that came out last year linking a genetically-modified strain of maize to huge tumors in rats, I’ve got another scientist saying the study should be given serious consideration.

Peat-Free Potting Soil Options

Most every commercial potting mix contains sphagnum peat moss because it’s a good, lightweight, organic amendment that improves drainage, as well as water retention and air circulation. The downside to peat moss is that it isn’t a sustainable resource. Peat moss is the decomposing remains of living sphagnum moss, and it is harvested at unsustainable rates from bogs in a manner than involves scraping off the top layer of the living moss to get to the saleable product below.

This process destroys centuries-old bogs, doing away with wildlife habitat, releasing C02 into the air, and eliminating wetlands that help prevent flooding. Because of this, conservationists and scientists all over the world have been pushing for limits and even bans on peat moss harvesting.

I grow all of my veggies and ornamentals without using peat moss.


In Britain, for example, where peat is often burned for fuel, harvesting has become so intense that the government has set goals for phasing out peat for home gardening use by 2020. Professional growers will need to go peat free by 2030. For more information, check out the Royal Horticulture Society’s website:

Most of the peat used by the horticultural industry in the U.S. comes from Canada where talk of limits and bans is also heating up. So, whether you are concerned about the sustainability of peat of not, now seems like as good a time as any to explore some peat-free potting soil options.

Straw Bale Gardening

People have been talking about straw bale gardening for years and, I admit, I haven’t really paid much attention. It’s not that I wasn’t curious about the idea. It just wasn’t on the top of my list of things to try until recently when I got the opportunity to talk with Joel Karsten about his new book Straw Bale Gardens: The Breakthrough Method for Growing Vegetables Anywhere, Earlier and with No Weeding.

Karsten tending one of his straw bale gardens

Karsten isn’t just another gardener talking about straw bale gardening. He invented straw bale gardening. That’s right; he came up with the idea for a growing technique that has now become an international sensation. And it all started when he was a kid growing up on a farm right here in Minnesota.

Farmers, he told me, have no need for piles of wet, unruly straw. So when a bale would break open for one reason or another and get rained on, his family would push it up against the barn to break down over time. “I always noticed that those stacked up, broken bales would have the biggest, tallest weeds growing out of them, so I knew there was nutrition in there,” Karsten recalls, adding that he didn’t think much more about it until 15 years later.

By then, he had earned a bachelor’s degree in horticulture from the University of Minnesota, and he and his wife Patty had just bought a house in Roseville. After looking forward to gardening at their new home, they were disappointed when they realized that their whole lot consisted of little more than construction debris in which nothing was going to grow well. Then, Karsten remembered those straw bales. “And I thought, what if I just line those bales up and try growing vegetables in them as they decompose?” he recalls.
