To help make our long winters less drab and dreary, I usually grow several different amaryllis plants so there is something colorful and blooming in the house between November and February. Normally, I toss the bulbs into the compost bins after they’re done flowering. But after talking to some master gardener friends who save and replant their amaryllis bulbs, I’ve decided to do the same. I figure, even if I didn’t pay a lot for the bulbs (they range in price), it would be nice to give the plants the opportunity to flower again if they’re able. If you’d like to try this, too, here are some tips you need to know.
Like other bulbs, amaryllis use their leaves to store up energy for next year. So once the flowers fade, cut them off so the spent blooms don’t go to seed, which uses up energy the bulb needs. Leave the long leaves intact. Yes it does look weird to have a bulb in a pot with goofy, long leaves poking out of it. But those green leaves will feed the bulb through photosynthesis if you leave the pot near a sunny window.
Keep watering and fertilizing the bulb as you did when it was flowering. I usually water once a week, which is when the soil starts to feel dry. It’s a good idea to fertilize every time you water. Use about half the amount suggested on the package of whatever type of fertilizer you use.
Once we make it past the last frost, put your amaryllis plants (in their pots) outside in a spot that’s not in direct sun. Like seedlings, they need some time to acclimate to being outdoors so over the course of a week or two, move the pots into more and more sun. Ideally, they need to end up in a place where they will get a minimum of 5 hours of sun daily. You can leave them on your patio in their pots, or bury the pots in the garden someplace for the summer. At this point the leaves may be yellowing, browning or otherwise looking awful. But even if they are still green, you can cut the foliage back to about 3 inches. Keep up the watering and fertilizing (now at full strength) during the summer and new leaves will grow.Read More»
As summer comes to an end, it’s tempting to bring tropical plants indoors for the winter. It’s not a bad idea, but as you probably already know, some of them don’t do so well in our cool, dry houses for months on end. The key is to offer the right amount of care, which sometimes means a lack of care, depending on the plant.
If you want to try to keep tropicals alive so you can bring them outdoors again in the spring, there are three ways to do it:
- Bring the plant in and let if just keep on growing in a warm sunny spot.
- Put the plant in a cool, dark place and let it go dormant.
- Take cuttings from plants you like, root them and pot them up so you can enjoy those new plants in the spring.
Going with option one means you need to have a sunny window where temperatures are between 60 and 75 degrees during the day and not below 45 at night. Jasmine, hibiscus, bougainvillea and small citrus trees are just a few of the plants that can survive the winter this way. If you don’t have that sort of sunny spot, you can always put plants under fluorescent lights or grow lights, but make sure you set a timer so they get about 12 hours of light daily.
If plants grow enough to get leggy, prune them back at least once. And do worry about a few dropped and/or yellowed leaves because that’s bound to happen, particularly right after you brings plants indoors. Water as needed, but don’t fertilize plants until spring. And be sure to inspect plants regularly for pests. If you find some they can usually be controlled by plopping the plants in the sink or shower and giving it a good blast with water.
Letting plants go dormant takes more of an understanding of plants’ individual needs. Good information on that can be found in the book, Bulbs in the Basement Geraniums on the Windowsill: How to Grow & Overwinter 165 Tender Plants by Alice and Brian McGowan. Basically, it all depends on whether the plants are woody, soft-stemmed or bulb-like. For example, elephant ears and caladiums should get a little bit frost nipped before they come inside so they understand that the season is over and it’s time to go dormant. They can either be stored in a cool, dark place right in their pots and your job is to keep the soil slightly moist until spring. Or, you can take them out of their pots, remove the stems and foliage and store only the bulbs. Read up on how to do that: everyone seems to have a way they like to do it.
Taking cuttings from plants that are difficult to overwinter, like coleus and geraniums, is easier than it sounds. If you’re going to do this, take the cuttings in the fall and toss the main plant (sometimes called the “mother” plant) in the compost bin. Instructions for taking cuttings and rooting them can be found in books, online and of course there are YouTube videos.
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»
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.
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»
I admit it. I have Home and Garden Show envy. I read blog posts by gardeners all over the world who talk about the innovative gardening products and to-die-for plants they just saw at their local Home and Garden Show. (Most of them post great photos, too, so I don’t think they’re lying.) Inevitably, their exuberance makes me feel excited about going to Minneapolis’ Home and Garden Show, which is ridiculous because I already know that our local show is totally lame. Lame, lame, lame! Year after year, I go because I get free tickets with a garden magazine I subscribe to. And every year I walk away complaining about how lame it is that people have to pay $11 per ticket, $13 at the door, to walk around a hot, windowless arena packed solid with trade show booths offering the same array of stuff: granite countertops, gutters, expensive kitchen gadgets, hideous bathtub and shower inserts, outdoor gazebos, patio furniture, flooring and hot tubs. So many hot tubs—$16,000 hot tubs.
Seriously, they should pay people to attend this event. Or at least let people in for free: the hope being that once they’re inside folks will buy some mini doughnuts and cheese curds followed by copious amounts of beer. Enough beer to, say, allow them to throw down a credit card for a hot tub as big as a Volkswagen. “Ah, who the hell cares where we’ll put it, honey. Let’s just get it!”
Okay, if you’re not a local, you’re probably thinking: “Hey, it’s not like anyone is holding a gun to people’s heads to make them go to this home show thing.” But you’re wrong. There is a gun, and it’s called winter. In Minnesota, by the time March rolls around, most of us would pay any amount of money to go anywhere to see anything different than what we’ve been looking at for five months indoors. Add the word “garden” to the name of the event, and you’ve got yourself a crowd. Even people that don’t give a hoot about plants will fork over cash just to see something ALIVE, maybe smell some dirt, see some flowers. We are a desperate lot.
But therein lies the problem. There ain’t much Garden in our Home and Garden Show. Yes, there are some interesting gardening talks given by local gardening gurus, as well as some of my fellow master gardeners. But those are usually off in some airless side room far from the arena’s main floor. To see actual plants you have to thread your way through countertops and hot tubs and super-absorbant sponges to get to one small area in the back of the arena where mostly lesser-known landscape design firms have their displays. Some years are better than others. This year, though, was just plain weird. For reasons I am completely unable to fathom, there seemed to be some kind of TV show theme to the booths. This would have been bizarre no matter what, but why Fantasy Island, Miami Vice and Gilligan’s Island? Did the organizers of this event swear off TV in the 1980s? Are the TV shows of my adolescence already so kitschy they’ve actually become cool?
Were people worried that visitors would be bored looking at some dumb, old plants outside the context of a TV theme? I don’t get it. Do you?
So, tell me. Do you have a good garden show in your city? If so, please email me a photo so I can live vicariously through you. Or, hey, maybe I’ll send them to next year’s local planning committee. They could use some ideas.
