My husband Mike and I were disappointed this spring when a Robin couple suddenly stopped building a nest above our back door and skedaddled for what we presume were more private spaces. Our friends Sher and Sarah were much more fortunate. Under the shelter of their front porch, robins built a nest, settled in and had a big family. Every spare minute, Sher and Sarah watched the robins coming and going with worms and other indiscernible food items that they dropped, and sometimes stuffed, into the four babies’ upturned beaks before hurrying back out for more.
All the jostling and wing flapping and cheeping was mesmerizing to watch, and they sat out on the porch quietly observing as often as they could. Sher is a freelance photographer, so she carefully climbed a ladder to get a shot when she could without disturbing the robin family. I want to share some of Sher’s photos with you because they’re beautiful, and they also offer a glimpse of something most of us never get to see, especially up close.
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»
Of all the things in our landscape, I think the galvanized cattle troughs (also known as stock tanks) in our backyard get the most attention. Even in the winter when nothing is growing in them, their shapes and sheer size turn heads and provoke questions. We added them to what we’re now calling “our little farm” a couple of years back when we lost a huge oak, and I figured I’d take advantage of the sun to grow some vegetables. After starting with one trough, we added another last year and we’ll be getting one more in the next few weeks.
If you want to grow some food on a small, urban lot, you can’t beat these troughs for being easy to get going. You don’t have to build anything, and you don’t have to deal with turning depleted urban soil into something safe, nutrient-rich and workable enough to grow food in. They’re also affordable, durable and tall enough to be out of the way of hungry critters and peeing dogs.
People ask all the time where we got the troughs and how to turn one into a raised bed garden, so even though I wrote briefly about this a couple of years ago, I thought I’d explain the process more in-depth here since it’s the perfect time to get raised beds going for the season. Let’s start with where to buy them. Unless you are literally made of money, do not go to a boutique garden center for a livestock trough. You want to go where farmers buy stuff—Tractor Supply Co. and Fleet Farm.
If you want to grow things like tomatoes, peppers, beans and squash, get yourself a large trough. One of ours is four feet long and the other is six feet. Both are 2 feet wide and 2 feet deep, and they cost about $80 and $110, respectively. Aside from getting the things home in the back of the car, the biggest job is drilling holes in the bottom for drainage. Use a bit that can drill through metal that’s about the size of a dime of nickel. We drilled holes every few inches all around the outside edge along the bottom, and then added many more holes going across the bottom of the trough from end to end and side to side. Remove the drain plug, too, since you won’t be needing it.
Once you’ve got your holes drilled, flip the trough over and put it wherever you want it because once you fill it with soil, you won’t be able to move it around without taking most of that soil back out. We don’t like things looking all kittywampus so we used a level to make sure the trough was lined up properly once we got it situated. (You don’t have to do that unless you’re bugged by such things.) Now comes the soil part. My advice—don’t cut corners. Good soil makes all the difference when you’re growing anything.
Because these are containers, albeit huge ones, you want a mix that’s going to drain well. You also want to provide plants with some nutrients that you’ll boost over time by adding compost and fertilizer. You’ll save some money if you make your own mix by combining 1 part topsoil, 1 part compost and 1 part coconut coir or coarse sand (also known as builder’s sand). I’ve done this by combining these things in batches in a wheelbarrow and it worked well. But I’ll admit, it’s a heck of a lot less work to call someone and have a quality potting mix delivered to your driveway. That way, you can just shovel it into a wheelbarrow and take it right over to your trough and other containers.
What do I mean by a quality mix? As I’ve said in the past, I’ve learned a lot about soil and compost over the last few years and I’m now opting to go with products that are organic or at least produced by a company or farmer who is willing to explain their process so I can make an informed decision about whether to use it. (For much more on that topic, see my blog post on safe compost.
Local organic growers give products from Purple Cow Organics, COWSMO and Mississippi Topsoil high marks. Other local sources that come highly recommended are Kern Landscape Resources and Kelley and Kelley Nursery. Compost from our Linden Hills organics recycling program is also pretty good. But because it includes packaging, paper and other odd bits, I don’t use it to grow edibles. That’s just me. Keep in mind that even though it’s costly to fill your trough with quality potting mix the first year, in subsequent years (unless you get some dreaded disease like early blight of tomatoes) you’ll only need to add a bit more compost to keep soil healthy. If you feel like you’re having drainage issues, add more coir or sand. With the hard part behind you—all you have to do is keep growing.
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»
