Hello dear readers. It’s been quite a while since I’ve posted a blog. Life gets too busy sometimes and you have to let go of at least a few things or you’ll go batty. (At least that’s how I work.) Now that the load has lightened up a bit, I’m back and I’ll try to post much more regularly going forward—at least during the growing season.
First off, happy spring! If you live nearby I want to let you know that the Little Free Seed Library is up and running again at my house, so please come on over and leave some seeds to share with others. Or take some home for yourself. This season, I’m happy to say that we have a few more items to share thanks to Do It Green! Minnesota.
The Minneapolis-based non-profit has long been committed to sustainability and promoting healthy communities, and with support from the Gannett Foundation they started up their own Do It Green! Seed, which provides free native and organic seeds to Twin Cities residents. They also distribute educational information about seed saving and other topics, and when they heard about my seed library, they kindly gave me a variety of seeds to share with you. They also gave me many copies of two handouts: One explains how to choose quality seeds and save seeds, and the other covers the different types of milkweeds home gardeners can plant to help monarch butterflies.
Both handouts will be in the library as long as supplies last. Or, you can print your own copy of Do It Green!’s Seed Saving handout by clicking on a link you’ll find on their website. Their site also offers a link to a very nice seed label that you can print and use on your own envelopes when saving seeds at home. Those of you who visit the library at my house will see that label on the seed packets donated by Do It Green!, which include swamp milkweed (Asclepias incarnata) and organic China rose radish, garlic chives and cilantro.Read More»
Want to grow vegetables and herbs even though you don’t have full sun? No problem. You just need to choose edibles that don’t depend on six hours or more of baking sunlight to thrive. So, yes, tomatoes are out, as are peppers, squash and eggplant, because plants grown for their fruit really do need a minimum of six hours of good sun per day.
But that still leaves a wide variety of edibles to choose from as long as you’ve got more than deep shape to work with—not much will grow under a maple tree’s canopy. But plants grown for their roots and flowers will produce with as little as three to six hours of full sun or consistent dappled sun. Beets, carrots, broccoli, cauliflower, onions, turnips and radishes, for example, can be successfully grown with four to six hours of sun. And though they produce fruit, I get a pretty good crop of cucumbers in 5 hours of sun.
Leafy veggies like kale, spinach, leaf lettuce, arugula, mustard greens and Swiss chard can get by with only two to four hours of sun—though they will grow more lush in sunnier locales. If you have a garden that offers both sun and shade, one of the advantages of knowing what can take less sun is the ability to increase your harvest by tucking these plants in along shaded borders that are often though of as wasted space.
Sure, there’s a lot to be said for the power of sun, but there are some benefits to growing vegetables in part shade. Crops like broccoli and cauliflower won’t bolt as quickly as they would in full sun, tender lettuces will last longer and you won’t have to water constantly, which is always a plus. That said, though, it is important to monitor moisture levels in shade gardens carefully because these sites are often located beneath big trees or shrubs, as well as the overhang of the house or garage. So even when it does rain, the water may not reach your garden, and much of what does fall will likely be taken up by the root systems of greedy trees and shrubs.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.
Some of you might remember a post I wrote last year about the ethics of taking seeds from other people’s gardens. Sure, it’s hard to resist pinching a few seeds off of other people’s plants when you see something you just love and figure “they’ve got plenty to share, right?” But is that really okay? Is it stealing? What if they don’t want to share?
Haunted by these questions after reading a blog post about a gardener who got chased and yelled at by an angry homeowner after taking a few seeds that had fallen on the SIDEWALK, I decided to try hard not to take seeds without asking. (I just can’t say never, but mostly never I can do.) Anyway, I also decided to figure out a way to share seeds with other gardeners, and I’m happy to say that the Little Free Seed Bank I dreamed of has been up and running for over a month. Here it is!
This summer, my husband Mike and I installed one of those Little Free Library boxes on our boulevard. If you haven’t heard of these libraries, they’re popping up all over the country and they’re a great way to share books with neighbors. Our library has been busy ever since we put it up with people of all ages stopping by to take a book or leave a book.
While both shelves will normally be for books, we’ve reserved the top shelf of our library for seed sharing during the spring and fall. So far, available seeds include: angelica, black-eyed Susan, anise hyssop, zinnias, cleome, ‘Painted Lady’ heirloom sweet peas (love these), garlic chives and blue delphinium. Individual seed types are packaged in large envelopes and gardeners can put the seeds they would like into small coin envelopes or little plastic bags that were donated by a kind neighbor. Pencils are also on the shelf so people can label the envelopes before they forget what’s inside—I know I would. (Those who take the plastic bags will need to have good memories.)
Lots of gardeners have stopped by to take seeds in the last few weeks. I’m hoping interest in the Little Seed Bank will grow over time and soon we’ll have more seeds to share than we know what to do with. If you live in town and would like to drop off or pick up some seeds, email me (meleah at everydaygardener.com) and I’ll give you directions. The more the merrier!
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.
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: http://www.rhs.org.uk/Gardening/Sustainable-gardening/Peat-and-the-environment/More-about-peat.
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.Read More»
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 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.Read More»
