onions and garlic, in frugal perpetuity

A quick way to clean the algae out of a garden water feature after a long, dark, and wet winter is to use a power washer. It only takes a few minutes to dislodge the long mats of algae, and the low volume of water that blows out of the nozzle doesn’t disturb even the smallest of rocks. Start at the top of where the water flows and work your way down to the bottom of the feature. This is a lot easier and more effective than grabbing the strands by hand and then using a brush to clean the rest away. You can see the difference in these “before” and “after” photos. I enjoy this a lot more than power washing the patio.

As native grasses such as little bluestem (Schizachyrium scoparium and cvs., Zones 3–9) and prairie dropseed (Sporobolus heterolepis and cvs., Zones 3–9) increasingly gain traction in gardens, exotics such as miscanthus (Miscanthus sinensis and cvs., Zones 4–9) are losing favor because of their invasive tendencies. But not all exotic grasses are troublesome and need to be avoided. Feather reed grass (Calamagrostis × acutiflora and cvs., Zones 5–9) is a natural hybrid of C. arundinacea and C. epigejos, which are both nonnatives and prolific self-sowers, but the hybrid rarely sets fertile seed—a major plus for an exotic grass, right? So why are other reed grasses—‘Karl Foerster’ aside—so underused? To answer that question is to understand the phenomenon of ‘Karl Foerster’ feather reed grass (C. × acutiflora ‘Karl Foerster’).

D espite our best efforts, we humans can’t do it all. Life in the 21st century often moves at a busy pace and is jam-packed with responsibilities and wonderfully abundant ways for us to spend our “free time.” While many of us love to spend a large chunk of that time enjoying our gardens, we don’t necessarily love (or have the necessary resources) to care for them. As a landscape designer, I’ve found that one of the best ways to create sustainable gardens for my clients is to develop designs that work with the sites, not against them, while also hitting on the clients’ wish lists.

Living and working in northwestern Oregon, garden designer Wesley Younie is no stranger to dealing with challenging environments. When presented with this garden’s elevation changes, drainage management, and extreme climate conditions, he devised a plan that addresses it all—along with a specific functional wish list from the homeowners. Want to know which plants he used? Here are the plant IDs for this beautiful, sustainable landscape.

Blue is not the colour you associate with foliage but if you can bend your eyes just a little around the silver – grey through to green spectrum there may be some surprises.

After salad crop failures in Spain and shortages of courgettes, broccoli and other ‘long distance’ vegetables gardeners could to worse than focus on traditional and non-traditional root crops.

When I first started exploring roses, I thought myself to be pretty educated once I knew the difference between a David Austin and a Knock Out. And then I discovered a whole new world of

St. Patrick’s Day, March 17, is a popular celebration in the United States, due to the number of Americans, 10.5%, with Irish heritage. One million Irish emigrated to North America, Australia, or other parts of Great Britain in the mid-1800s because of the potato disease now known as late blight. Late blight, caused by the water mold, Phytophthora infestans, destroyed the Irish potato crops in 1845 through 1849 and caused the Irish Potato Famine. Another one million people died from hunger or disease.

Start with a cold-hardy cultivar if you plant to try to overwinter rosemary in the ground in other than a truly frost-free hardiness zone. ‘Arp’ is the best known, along with ‘Hill Hardy’ (also known as ‘Madalene Hill’ after the late herb gardener from Texas; ‘Arp’ was her discovery, by the way, the result of her search for plants that could take not extremes of cold but the Texas heat). Oregon-based Nichols Garden Nursery’s owner touts ‘Nichols Select’ as being a toughie, too.It’s “as hardy as any I’ve grown, probably Zone 6B, and the flavor is terrific,” Rose Marie Nichols McGee in an interview one spring. “It was planted 25 years ago at our home and survived minus-7 degrees F once. I think this is your best for a long-lived rosemary.”The U.S. National Arboretum website trialed many cultivars, and how they fare on all scores. Even in USDA Zone 7A,

IT’S EITHER TIME TO HIT THE SLOPES, or hit the bar, Andre Jordan–or at least that’s how it looks from conditions as depicted in your latest doodle.

The pre-Columbian Indians of the Andes domesticated more starchy root crops than any other culture, but only the potato caught on as a staple worldwide.“The others have seldom been tried outside South America, yet they are still found in the Andes and represent some of the most interesting of all root crops.…” said a 1989 report called “Lost Crops of the Incas: Little-Known Plants of the Andes with Promise for Worldwide Cultivation” from the National Research Council.“They come in myriad colors, shapes, and sizes,” the report added. “T

IN SOME THINGS lonerism backfires, like when the ladder needs steadying to get at the top of an errantly sprouting espalier, or a truckload of eight cubic yards of mulch is dumped by the far gate. Though ordering seeds is not heavy work, it is best not done alone, either; I have always had a companion for the task. My latest one, of considerable years’ duration, got it in his head to move to Oregon recently, for greener garden pastures, taking with him not just the in-person dimension of our friendship, but also access to the nearby greenhouse that was, of course, a perfect complement to the shopping we did together all that time.“I’ll buy the tomato seeds if you’ll grow them,” the conversation with Andrew would always begin, as if he needed my ten- or fifteen-dollar annual enticement, when of course we never really paid careful mind to who bought what or really kept a running tab of our years-long botanical barter. It hardly mattered; what counted was the chance to look together, to compare notes, to react collaboratively to the possibilities—ooh! aah! ugh!—and eventually to relish the harvest (or to commiserate when something was a flop and there was no harvest, or
