As Digital Content Editor Christine Alexander explains, pollinators play a vital role in our ecosystem and we should all be doing our part to support their populations:

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.

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.

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,

The Deer’s Delicate Palate: We all wonder (often in loud expletives when something has been chewed) what it is that deer won’t eat. I loved this online tool created at Rutgers University Extension (based on observations in northern New Jersey) that rates things from “Rarely Damaged” to “Frequently Severely Damaged” (above) in a five-point scale that seems more sensible to me that saying anything’s “deerproof.” We could all benefit from this kind of thinking, a sort of risk-assessment philosophy of planting in the presence of these beasts. (You know me; I don’t. I gave up and got a deer fence.)Compost-Bin Envy: I have never met Ryan Boren, one of the lead developers (read: software engineer) for WordPress, the platform I so love and that this site is built on. Who knew that Boren is also adept with wood-working tools and built himself a composter-to-covet at the Texas home he shares with his growing family and some mighty cute goats. The “after” shot of his three-stage compost bin is here; the detail shots here.An Old Friend, Overplanted:

I don’t even know if this lone pear, with its handsome lichen-covered trunk (background, below), is “wild,” or was planted by a previous owner, as were the remaining half-dozen or so big old apples that have already seen most of a century on this land, a remnant of a long-ago fruit orchard.Each year I’ve just enjoyed the pear for the character-filled tree that it is, and written off the fruit as useless, and a nuisance at that, since much of it drops to the ground and creates an experience not unlike mowing over golfballs (if you don’t slip and fall first after stepping on one).  Birds and other wil

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

I’ve never grown multiplier onions before, an oldtime favorite I pre-ordered in March from Southern Exposure Seed Exchange, which offers them for fall arrival. I haven’t found much consistent information about growing the so-called potato onions, particularly in the North, except for Southern Exposure’s fact sheet, which says to save half the bulbs for springtime planting in case the winter’s too hard for them. Sounds a little ominous, but here I go.In my cold area, I’m meant to give them up to 5 inches of soil on top of their pointed ends (only 1 inch or 2 in warmer zones), then scrape some of it away come spring, as they prefer to be closer to the surface in the growing season. As with garlic, shallots and other alliums, the bulbs want fertile, well-drained soil and a sunny location to be happiest.I’d welcome any insights or war stories if you’ve grown multiplier onions, which are also sol
